New Study Reveals How Cannabis Suppresses Immune Functions

119,120 Using peritoneal macrophages from diabetic mice stimulated ex vivo with LPS revealed that macrophages isolated from CBD-treated mice did not produce as much TNF-α or IL-6 as macrophages isolated from vehicle-treated mice. THC and CBD suppress the abilities of macrophages and T cells to make those proteins (2, 3). This leads to chronic inflammation and could therefore have adverse effects to one’s health. An increase in your appetite is common when taking any form of marijuana, leading to what many call “the munchies. Nor was cannabis use related to changes in a limited number of measures of immunological functioning. Neuropharmacology (2020) 113:

The endocannabinoid system is home to a vast network of cells that have cannabinoid receptors on them. These include corticosteroids, intravenous immunoglobulin, plasma exchange and immunotherapy. Today, they're also gaining popularity for their positive effects on the human immune system. The portion of the immune system that you can actually see is called the innate defense system — this includes the skin as well as the mucous membranes of the nose, eyes, ears, and mouth.

165 Adoptive transfer EAE is a variation of the EAE model induced by transfer of encephalitogenic T cells into naive mice, which allows experiments performed with this model to focus more on the T cell-specific mechanisms of pathogenesis in the EAE model.

In 2020, National Institutes of Health researchers concluded that activating the endocannabinoid system played a role in the overall health of the intestinal track for celiac patients. In the context of autoimmune diseases, suppression of the immune system by THC and CBD would be a welcome outcome, and indeed is the current target of therapy. Upon identification of the cannabinoid receptors, CBD was determined to exhibit low affinity for CB 1 53 and CB 2 receptors. THC administered to mice who have influenza produces an immunosuppressive effect which impairs the response to the pathogen (Karmaus et al. Robot check, here's a look at five types of nutrients that your immune system needs to perform and which foods to find them in. )However, receptor Taar1 is also expressed in lymphocytes, which suggests a potential immunomodulatory capacity for MDMA (Nelson et al. )

Katz D, Katz I, Porat-Katz BS, Shoenfeld Y. Back then, no one questioned how or why cannabis relieved pain and calmed the spirits. J Biol Chem (2020) 286: CBN-rich products are also harder to find as it requires THC to be exposed to oxygen over time; however, products with pronounced CBN profiles are available. Anticancer effects of phytocannabinoids used with chemotherapy in leukaemia cells can be improved by altering the sequence of their administration. Medications for human papillomavirus, statistically significant reduction of relapse rates has been shown in Group A in patients over 25 years old. Accordingly, THC is thought to show promise for autoimmune diseases, such as Crohn’s and multiple sclerosis. “Classical” CB 1 signaling (green) and beyond: Blumstein GW, Parsa A, Park AK, McDowell BLP, Arroyo-Mendoza M, Girguis M, et al.

Journal of Molecular Medicine (Berlin). (2020), less address the long-term implications of medicinal hallucinogenic use. Symptoms of THC ingestion include appetite stimulation, mild psychotropic hallucinations, relaxation, euphoria, and anxiety (Wiley et al. )It triggers the self-destruct part of the immune response that tells a diseased cell to live or die.

Autoimmunity (AI) is an "attack on self", where the immune system gets triggered and thinks that the body's healthy tissues are invaders.


The adaptive immune system has two key mechanisms: In assessing these responses, various cell types and their functions have been examined. 147 CBD (10 μM) was shown to affect several genes involved in lipid metabolism in unstimulated BV-2 cells,157 which might account for CBD's ability to increase anandamide58,65–67,84,157,160 or could account for CBD's dependence on lipid raft formation to induce apoptosis156,157 Follow-up studies examining CBD's effects in unstimulated BV-2 cells demonstrated that CBD (10 μM) alters zinc homeostasis, oxidative stress, and glutathione levels in microglial cells. The HIV/AIDS virus incapacitates the primary defenses of the immune system by attacking collections of certain cells known as CD4 and CD8. The ECS is a homeostatic regulator – continually working to maintain a state of biological balance.

People report various physical and psychological effects, from harm and discomfort to pain relief and relaxation. Different cells control adaptive immunity, which takes place when B lymphocytes produce antigens in response to foreign antibodies and attack the foreign invader. This is an exceptionally serious and pertinent question, especially for patients who are interested in using medical marijuana to combat long-term, chronic illnesses. There will also be a description of CBD effects in animal and human immune responses, a characterization of mechanisms by which CBD mediates immune effects, and identification of knowledge gaps regarding CBD's actions in the immune system. No matter how you use marijuana, the drug can cause immediate and long-term effects, such as changes in perception and increased heart rate. Cannabidiol for neurodegenerative disorders: CBD (1–16 μM) was shown to induce apoptosis in mouse thymocytes and EL-4 T cells.

1634/theoncologist. 24mm unframed pendant set in silver, immune-mediated drug-induced liver-injury (DILI) in humans is one of the specialist areas where we have studied several key events (KEs) important both for prediction and diagnosis. Bear in mind, however, that as of right now all of this research is still speculative in nature. It may also mean THC could be used when there is a need to suppress the immune system – after an organ transplant, for example.

Lazzerini PE, Natale M, Gianchecchi E, Capecchi PL, Montilli C, Zimbone S, et al.

Cannabis, Cancer, & the Immune System

The immune response is initialized in these tissues upon detection of antigens or microbes. 5–50 mg/kg for oral 10 days Male ICR mice Carrageenan-induced inflammation ethosome (CBD in ethosomal gel) ↓inflammation 198 100 mg of ethosomal CBD (3%) Male Wistar rats Carrageenan-induced inflammation Oral ↓disease, ↓prostaglandin (PGE 2 ) 199 5–40 mg/kg 3 days Female NOD mice Diabetes i. For example, some cells of the immune system (white blood cells such as macrophages and T cells) detect foreign invaders of your body (e. )For this reason, people with HIV/AIDS’ response to cannabis suggests how everyone’s body interacts with cannabis. Extensive research has been performed on the anti-inflammatory properties of THC, CBD, and other cannabis components. How to boost your immune system by eating the right foods. Epigenetic regulation of immunological alterations following prenatal exposure to marijuana cannabinoids and its long term consequences in offspring. My scientific area of expertise is called immunotoxicology.

Massive amounts of these cells also lead to cancer growth. 143 Interestingly, “IL-17 signaling” was also identified as a critical pathway suppressed by CBD (5 μM) in T cells in vitro. In the medical world, the term “immune health” is incredibly broad, and it can invoke a number of different clinical interpretations. These receptors are designed to interact actively with cannabinoids in a variety of ways. 68,69 A recent study suggested that the mechanism by which CBD elevates anandamide involves CBD interaction with fatty acid binding proteins, which prevents anandamide binding to these proteins to block anandamide transport to FAAH. However, this study revealed that even short-term marijuana use can help these important cell groups stay healthy and strong. All authors wrote, edited, and approved the final version of this manuscript. Taking a toll on neuroinflammation.

  • Their study included the pain-relieving compound delta-9 tetrahydrocannabinol (THC).
  • In the near-future, we will hopefully begin to discover more about the role cannabis plays in the health of the immune system and how it can be used to treat a truly wide spectrum of health conditions.
  • While inflammation has a bad reputation, no human would be able to survive without it.
  • Besides humans, all vertebrates have this system, alongside many other non-vertebrate life forms.
  • Optimum immune function entails a complex balancing act that relies on constant communication between our immune cells, tissues, and organs.
  • Cannabis sativa has been consumed for health and nutritional purposes for thousands of years.

Circulatory System

How have treatments for HIV/AIDS patients helped us determine marijuana effects on the immune system? Altogether, these data clearly indicate that memory problems can occur on the basis of both overactivation and critical impairment of CB 1 signaling. Unlike autoimmune disease, HIV/AIDS and cancer are associated with a decline or suppression of our immune function. Drink these 8 teas to boost immune system and reverse illnesses. There are more than 100 diseases categorized as autoimmune conditions, with some of the more-often-diagnosed conditions including psoriasis, rheumatoid arthritis, lupus, irritable bowel syndrome, and Crohn's disease. Cannabinoid receptors and their ligands: The concentration of HIV in one’s blood determines the number of CD4 cells. In an animal model of multiple sclerosis, CBD decreased the gene transcription that promoted inflammation. Our immune system is primed to spot rogue cells and, through mechanisms such as apoptosis, eliminate any that might become tumors.

While some studies have been done on the effects of THC, and to an extent on the effects of MDMA, there is a lack of information available on the long-term effects regarding immunomodulation and THC. Previous studies have hinted at immune system abnormalities among cannabis users -- specifically, in the function of immune system cells called T lymphocytes and natural killer cells. Cannabidiol (CBD) as Epidiolex ® (GW Pharmaceuticals) was recently approved by the U. In some cases, though, the immune system may be unable to distinguish between external dangers and the body’s own natural, innocuous cells and processes. Chronic administration of THC induced intestinal anti-inflammatory miRNA expression during acute Simian Immunodeficiency Virus (SIV) infection of rhesus macaques (153), and did not increase viral load in brain tissue (154). Squintani G, Donato F, Turri M, Deotto L, Teatini F, Moretto G, et al. 2020; Wei et al.

In the body, MDMA is metabolized in the liver and acts on several regions of the brain and immune system (Kalichman et al. )Moreover, it was also shown that under certain conditions, THC could even enhance Human Immunodeficiency Virus (HIV) antigen-specific immune responses, which occurred through both CB 1 /CB 2 -dependent and -independent mechanisms (156), and findings showed no evidence for a negative effect of cannabis use on circulating CD4+ T cell counts/percentages in HCV-HIV coinfected patients (157). And finally, make sure to always do thorough research on your own and use CBD under your own judgment. Last, but not least, transient administration of the CB 2 inverse agonists AM630 (10 mg/kg) or JTE907 (3 mg/kg) during immunization was found to improve antigen-specific immune responses in young and aged mice through the upregulation of immunomodulatory genes in secondary lymphoid tissues (149). Its multiple components include: “Marijuana cannabinoids present us with a double-edged sword,” Nagarkatti said.

  • What products and delivery systems might work for me?
  • VCE-003 inhibited the secretion of Th1/Th17 cytokines and chemokines in primary murine T cells and dampened the IL-17-induced, proinflammatory M1 polarization of macrophages in a CB 2 and PPARγ-dependent manner (101).
  • 155 We conducted a similar study using oral administration of CBD and also found modest inhibition of antibody production.
  • The location of the autoimmune attack will vary based on the condition.


However, one particularly interesting therapeutic application of the ECS is its effect on the immune system, or what some scientists refer to as “immuno-cannabinoid” modulation. Some of the most common autoimmune diseases include psoriasis, which affects the skin; Crohn's disease, which affects the digestive system; and multiple sclerosis, which affects the brain, spinal cord, and optic nerves. In addition, a small but growing body of preclinical data suggests that combining CBD and THC with conventional chemotherapy and radiation could have a powerful synergistic effect as an anticancer treatment. Research efforts of the past few decades have unambiguously evidenced that ECS is one of the central orchestrators of both innate and adaptive immune systems, and that pure pCBs as well as complex cannabis-derivatives can also deeply influence immune responses.


CBD, Cannabidiol; MDSCs, myeloid-derived suppressor cells; Treg, regulatory T cell. What does this mean in practical terms if you regularly use cannabis, have a compromised immune system or are starting immunotherapy? Given the duration of large-scale cannabis use by young adults in Western societies, the absence of such epidemics makes it unlikely that cannabis smoking produces major impairments in the immune system. WHAT ARE THE PROS AND CONS OF CANNABIS? That rapid heartbeat can continue for up to three hours. There are several reports that CBD acts through the serotonin 5-HT1a receptor (Table 1). The clinical significance of these possible immunological impairments in chronic cannabis users is uncertain. If you have been considering taking CBD for immune system health or an autoimmune condition that you already have, be advised that there are dozens of high-quality CBD oils and tinctures available for sale online.

Everything you need to know about the annual MPS therapy week

It does this by decreasing inflammation, which is the body’s natural response to infection. In the primary lymphatic organs (i. )Nagarkatti’s team demonstrated that cannabinoids can trigger a massive number of MDSCs through activation of cannabinoid receptors. J Neuroimmune Pharmacol 9: Proceedings of the National Academy of Science.

  • Ulcerative colitis induces changes on the expression of the endocannabinoid system in the human colonic tissue.
  • The study highlights that these alterations of immune responses by cannabis use might be associated with increased susceptibility to infections and hence the higher white blood cell count, however, it notes that it is possible that the elevated white blood cell count and suboptimal health status contributed to cannabis use rather than cannabis use caused suboptimal health.
  • The endogenous cannabinoid anandamide potentiates interleukin-6 production by astrocytes infected with Theiler’s murine encephalomyelitis virus by a receptor-mediated pathway.
  • It is more difficult to exclude the possibility that chronic heavy cannabis use produces minor impairments in immunity.


Roth MD, Tashkin DP, Whittaker KM, Choi R, Baldwin GC. Although most of the evidence for the involvement of this receptor comes from the attenuation of CBD's effects using the 5-HT1a antagonist, WAY100635, early studies demonstrated that CBD displaced binding of the 5-HT1a agonist, 8-OH-DPAT, in membranes from CHO cells expressing the human 5-HT1a receptor. CBD has also been found to increase the expression of genes that deal with oxidative stress, which may reduce cell damage from autoimmune attacks. Furthermore, the science behind marijuana use is ongoing, especially in the context of medicine. ● Cannabis vs Celiac Disease - The compound THC helps to slow down the digestion and movement of food in the digestive tract while CBD helps against autoimmune attacks on the small intestine caused by gluten. This comparison of HIV and the simian counterpart SIV with diseases such as influenza indicate that there are differences in how hallucinogenic compounds and immune system modulation affect each other.

  • There’s the answer to your question.
  • CB2 receptors in mice models have been shown to affect neurons in addition to having immunosuppressive actions (Yun et al.)

CBD Effects in Autoimmune Disease Models

It has been established that the immune system plays a critical role in many of these neurodegenerative and neuroinflammatory conditions. There have been no demonstrations that such tolerance occurs in animals, in part because most studies have used short duration, high dosing schedules rather than chronic high dosing required for tolerance to be demonstrated. The terpene beta-caryophyllene, found in certain strains of cannabis and black pepper, is known to decrease inflammation through its ability to stimulate the CB2 receptor. A new wave of research and mounting anecdotal evidence points towards cannabinoids having an adaptive, immunomodulating effect, rather than just suppressing immune activity. What are the effects of medical marijuana use on the HIV/AIDS virus?

Bial incident raises FAAH suspicions.

2 Experimental data in healthy persons have found abnormalities in T lymphocyte and natural killer (NK) cell function, but have not confirmed that these alterations might affect susceptibility to infections. Studies involving animals showed that THC might damage the immune system, making you more vulnerable to illnesses. The researchers say phytocannabinoids – chemicals in the plant – need to be explored more as a source of anti-cancer benefits. In cell-mediated immunity, specialized T-cells and natural killer (NK) cells seek out and neutralize pathogens, viral infected cells, and tumor cells. Several years ago, a colleague set me straight: AIDS Res Hum Retroviruses.

According to Polston, the two cannabinoids that appear most beneficial for treating the inflammation associated with autoimmune diseases are CBD and THC. You’d need high doses of THC, the psychoactive compound, to invoke an autoimmune response, while full spectrum CBD-rich products do not have the psychoactive qualities while seemingly providing relief for a wider number of autoimmune disorders. Immune system: diseases, disorders & function, the majority of children with a PIDD live active lives. It is possible that by replacing missing endocannabinoids, the cannabidiol in medical marijuana helps to restore the balance of the immune system.

There’s probably more research that needs to be done on this particular reaction. If it was ethical to conduct trials of the therapeutic use of cannabinoids in AIDS patients, then monitoring the impact on immune functioning would provide one way of evaluating the seriousness of the immunological effects of cannabinoids, not only for AIDS patients, but also for other immunologically compromised patients using cannabinoids for therapeutic purposes. Croxford JL, Yamamura T. Endocannabinoids are produced on demand, travelling backwards across chemical synapses and modulating cell activity. How to boost your immune system to help avoid coronavirus covid-19. Combined with its pain-relieving properties, cannabis allows CIDP patients to live fuller, happier and healthier lives. These exciting results have also been replicated in humans.

Following up the line of the possible long-term consequences of marijuana consumption, it is important to note that although acute THC exposure in adolescent mice is anti inflammatory, it also has long-lasting proinflammatory effects on brain cytokines, and this modulation may affect vulnerability to immune and behavioral diseases in adulthood (170, 171). The absence of such epidemics among cannabis users does not, however, exclude the possibility that chronic heavy use may produce minor impairments in immunity, since this would produce small increases in the rate of occurrence of common bacterial and viral illnesses (Munson and Fehr, 1983) that would have escaped the notice of clinical observers. 89 The studies also demonstrated that CBD suppression of tumor necrosis factor-alpha (TNF-α) could be reversed using an adenosine A 2A receptor antagonist, and CBD-induced suppression of LPS-stimulated TNF-α was not observed in adenosine A 2A receptor knockout mice. Immunosuppression mediated by mdma and thc, one of the ways cannabinoids influence the ECS is by stimulating a specific response from the immune system. To put it simply, cannabinoids are the chemical compounds that are components of the cannabis plant. J Neuroimmunol (1989) 23:

  • As a result, the body is unable to fight off infection and make patients more prone to infection, which, in turn, can result to premature death.
  • 1 mix with incomplete Freund’s adjuvant in mice.
  • Spelman, Kevin.

While routine, recreational use of marijuana may have adverse affects on an individual's overall health and well-being, research from the targeted use of cannabinoids for the purpose of boosting the immune system is overwhelmingly positive. They are meant to be taken on the short term. Cannabis can strengthen the immune system and fight cancer, according to research. The endogenous cannabinoid system, also known as ECS, is a complex network of lipids and receptors. However, the drug is widely used for recreational purposes and can make users feel relaxed and happy. A recent epidemiological study by Polen et al (1993) which compared health service utilisation by non-smokers and daily cannabis-only smokers provided the first suggestive evidence of an increased rate of medical care utilisation for respiratory conditions among cannabis smokers. Indeed, CB 1 is generally considered to signal through G αi protein leading to a decrease in the intracellular cyclic adenosine monophosphate (cAMP) level, and activation of the β-arrestin 1 and 2 pathways. Goldstein reported that after two months on cannabis the patient discontinued three of the pharmaceuticals, experienced a significant improvement in her pain symptoms, and was "able to participate in her life again".

The review then provides a summary of in vivo and in vitro effects in the immune system, in autoimmune models, with a focus on experimental autoimmune encephalomyelitis, and ends with identification of knowledge gaps.

This ultimately leads to the cells growing out of control. However, at this point of research, it is still too early to say whether consuming cannabis with a healthy immune system would lead to any negative health effects. Studies suggest chemicals called phytocannabinoids could stop cancer cells multiplying and spreading, block the blood supply to tumours, and reduce cancer's ability to survive chemotherapy. People with Crohn’s disease have very low levels of natural cannabinoids. Alcohol and cannabinoids differentially affect HIV infection and function of human monocyte-derived dendritic cells (MDDC). Another critical determination needed for many of the receptor studies is identification of the cell type(s) on which the receptors are expressed, which are mediating the CBD effects. Turning over a new leaf:

Cannabis & the Immune System

Taha T, Meiri D, Talhamy S, Wollner M, Peer A, Bar-Sela G. What is cause of immunosupression in diabetes melitus? The variety known as cytotoxic or 'killer' T cell looks around the body for cells with antigens on their surface, and destroys them before they can do any harm. A Review of Clinical Effectiveness, Safety, and Guidelines. Some cannabis terpenes – such as beta-caryophyllene and myrcene – have shown to have anti-inflammatory properties as well; however, not all cannabis contains the same terpene profiles but in legal and some medical states terpene profiles are made available to consumers. ” We believe when you start something new, it’s best to start slow.

Understanding how the immune system normally functions and how it is impaired is important for comparing it to an immune system with hallucinogens. Cannabinoid receptors CB1 and CB2, MDMA receptor Tarr1, and stress hormones all play a role in mediating immune responses (Roth et al. )There is no cure for CIDP, but the most common treatments deal with its effects on the immune system.

However, the little research that has been conducted has been very promising. The mental health survey specifically measured anxiety, depression and energy levels. Trillions of friendly bacteria living in our digestive systems help to break down foods for absorption into the bloodstream, and synthesize vitamin B and vitamin K. It can also contribute to mental health problems among people who already have them, or increase users’ risk of psychosis or schizophrenia, according to research. 11 Curiously, subjects taking medical cannabis high in THC responded better to immunotherapy than those on a low strength THC product.

Medicine & Health

A 2020 study in the journal Digestive Diseases and Sciences builds upon these findings by demonstrating that Crohn's patients who use cannabis are less likely to experience serious complications (such as blood transfusions and abscesses), compared to patients who abstain from cannabis. 1080/17512433. Their primary health fear is the fact that the most common way cannabis users ingest their favorite plant is through smoking.

  • Furthermore, it diminished axonal demyelination and modulated Th1/Treg immune balance through the activation of CB 2 (102).
  • Cabral GA, Ferreira GA, Jamerson MJ.
  • As you may remember, the endocannabinoid system, or ECS, is a network of cannabinoids and receptors that works to regulate most functions in the human body.
  • However, if you already suffer from another chronic lung condition (such as asthma or COPD) or have a family history of developing lung illnesses, you may want to avoid smoking or vaping medical marijuana products.
  • Some studies suggest that cannabinoids like THC and CBD are immunosuppressant, which can explain the relief experienced by medical cannabis users with autoimmune diseases and chronic inflammation.

Here’s what happens to your body when this drug enters your bloodstream. There are a number of options available to you in Florida to get a valid medical marijuana card. Pyszniak M, Tabarkiewicz J, Łuszczki JJ. While it is difficult to detect a small increase in the incidence of infections in an individual or among a small sample of people, such an increase may have great public health significance. Within the “classical” ECS, the anti inflammatory CB 2 appears to be the most promising candidate to adjust such immune responses, but recently other receptors (e. )

The study was published in the British Journal of Pharmacology.

Interestingly, the ECS and cannabinoids have been shown to play a key role in “balancing” the various arms and components of the immune system. Δ9-Tetrahydrocannabinol (Δ9-THC) promotes neuroimmune-modulatory microRNA profile in striatum of simian immunodeficiency virus (SIV)-infected macaques. Theoretically, administration of endo- and pCBs may hold the risk of dampening appropriate immune responses, and thereby increasing susceptibility toward infectious diseases. Considering today’s greater access to medical marijuana and increased knowledge of its benefits, this percentage would be higher if the same study were conducted in 2020. Moreover, a common dinucleotide polymorphism of CB 2 , resulting in a Gln → Arg substitution (Q63R), which is accompanied by a reduced capability of CB 2 -mediated signaling to suppress T cell proliferation (67), was associated with an increased risk of immune thrombocytopenia (68), and celiac disease (69). In a related study, also published in the European journal of Immunology, Dr Christian Vosshenrich from the Institut Pasteur in Paris, reveals that when cancer cells grow they produce a molecule called interleukin-1 β (IL-1β), which also triggers MDSCs. These ligands, together with multiple receptors (e. )Indeed, certain control over the overwhelming inflammatory processes in, e.

The researchers injected one group of mice with THC and compared them with a group not injected with the compound. Celiac disease, for example, effects 1 in 141 Americans but is not a qualifying condition under any medical cannabis program in the U. Eating well during and after treatment, fiber is beneficial because it can help women control their appetite and may decrease the number of calories they consume. Soethoudt M, Grether U, Fingerle J, Grim TW, Fezza F, de Petrocellis L, et al. Cannabis is an extremely versatile plant, but it all comes down to each patient’s unique situation. These cells become active when swelling occurs, and are important first responders to prevent infection (Vagasi et al. )That is yet another reason that most cannabis research has involved observing patients suffering from extreme, life-threatening conditions such as HIV/AIDS or cancer. The relevance of these findings to human health is uncertain:

One of the ways cannabinoids influence the ECS is by stimulating a specific response from the immune system.

Marijuana Could Even Improve Immune Function

Cannabis can induce hunger and suppress the immune system, which is a primary reason for its interest regarding palliative care and as a new appetite stimulant over other current drugs (Wiley et al. )When you inhale marijuana smoke into your lungs, the drug is quickly released into your bloodstream and makes its way to your brain and other organs. These reports are difficult to evaluate because of the confounding effects of poor living conditions and nutritional status, although it may be that the small human immunological impairment predicted from the animal literature is most likely to be seen among such populations (Munson and Fehr, 1983). Managing autoimmune disease requires dietary and lifestyle changes, which have been reported to help reverse these conditions. MCT-14-0402 doi: Stress-Induced In Vivo Recruitment of Human Cytotoxic Natural Killer Cells Favors Subsets with Distinct Receptor Profiles and Associates with Increased Epinephrine Levels. Typical proinflammatory cytokines include IL-1α, IL-1β, IL-6, TNF-α and IL-17A, while IL-10 is considered anti-inflammatory. 119 CBD induced expression of IκB-α in heart tissue from diabetic mice in vivo120 and in LPS-stimulated microglial cells in vitro (CBD 1–10 μM).

The ECS is widely expressed in the human body, including several members of the innate and adaptive immune system, where eCBs, as well as several pCBs were shown to deeply influence immune functions thereby regulating inflammation, autoimmunity, antitumor, as well as antipathogen immune responses, etc. 5 or 5 mg/kg 14 days Male CD-1 mice Diabetes i. Cannabidiol (CBD) is a plant-derived cannabinoid that has structural similarity to the primary psychotropic congener in cannabis, Δ9-tetrahydrocannabinol (THC). A Systems Biology Analysis. Moreover, TLR and cannabinoid receptor cross-talk (84), as well as novel, “ECS-related” receptors (GPR18 and GPR55) have all been suggested to play a role in the pathogenesis of MS (85), and CB 1 (86–88), but especially CB 2 also emerged as a remarkably powerful and multifaceted future therapeutic target in this disease (88–100).
