How Breast Milk Changes

Human milk is a gold mine of uncharacterized, natural innate bioactive factors that have great promise to be developed and utilized for therapy or treatment of infections and inflammatory conditions in infants as well as adults and the elderly. Whenever a mother expresses her breast milk, she should wash her hands well with soap and water and, if using a pump, follow recommendations for proper cleaning. The WHO infant feeding guidelines advise the use of donor milk when the mother's milk is not available. There are several modes of transmission including direct contact, indirect contact, the airborne route, the vehicle mode of transmission and the vector mode of transmission. But very few studies have looked at how many immune cells there are in mature breast milk, which is what the baby receives most of the time it is breastfed. HIV-1 reservoirs in breast milk and challenges to elimination of breast-feeding transmission of HIV-1. Certain immune cells in human milk are phagocytes that attack microbes directly. Roughly two-thirds of mothers who intend to exclusively breastfeed their babies do not end up doing so.

Furthermore, breastfeeding protects infants against 50% of all diarrhea episodes and a third of respiratory infections in infants who are not breastfed (12). Lendahl U, Zimmerman LB, McKay RD. It’s also true that human colostrum and milk are rich in maternal antibodies—colostrum is pretty much antibody soup. Bio-active constituents of human milk that have been cataloged to possess immune-modulating capabilities include immunoglobulins, Lactoferrin, Lysozyme, oligosaccharides, lipids, cytokines, hormones, and growth factors. Vehicle transmission occurs when a person comes into contact with an infectious product that is in water, blood, and even inanimate objects like a toy or a door knob. The time is long overdue for moms to unite in sisterhood, putting an end to judgment and bottle-shaming once and for all.

Prevention of MTCT of HIV-1 is likely due to multiple factors, including innate immune factors such as lactoferrin and elafin among many others.

Most of the cells are neutrophils, a type of phagocyte that normally circulates in the bloodstream. While the transfer of low concentrations of milk-derived CTLs may favorably supplement the immature adaptive immune system of the neonatal gut, higher microchimerism might detrimentally lead to exacerbated inflammatory responses that can cause early intestinal tissue damage. If the baby is too sick to breastfeed, expressed breast milk can be given from a cup, bottle, syringe, or eyedropper. Breastfeeding lowers your baby's risk of having asthma or allergies.

Broccoli is super-charged with an arsenal of vitamins and minerals. As a breastfeeding mother, you can feed your baby even during stressful times such as when normal supplies of food and water are not available. These investigators also showed that miR-155 inhibited HIV-1 at a postentry, pre-integration step (183). HIV-specific secretory IgA in breast milk of HIV-positive mothers is not associated with protection against HIV transmission among breast-fed infants. The functional enrichment analysis of the 477 differentially expressed genes revealed a significant abundance of immune system-related activities (Fig. )Although the reason for this remains unclear, coordination of a number of innate immune factors in breast milk seem crucial for providing protection when infants are most vulnerable. 9 The time saved for mother is also immense.

Drannik AG, Henrick BM, Rosenthal KL. (In this regard, human colostrum has always been found to contain a considerable number of viable leukocytes [range 32 175–784 080 []; 8470–1 510 000 [] per ml milk), while transitional and mature milk forms are characterized by low leukocyte content (less than one tenth of the colostral leukocyte content) when both the mother and/or the infant are healthy []. The interaction of infant formula with macrophages:

Normally breastfed infants receive ∼94 000–351 million leukocytes from breast milk on a daily basis []. Generally speaking, surgical asepsis is used when internal areas are cared for and when the skin is not intact. A foreign and unnatural substance that provokes the body to produce antibodies to fight if off.

Premature babies are particularly vulnerable, as they don’t receive the 40 weeks gestation time to receive the full maternal passive immunity that a term baby does.

Fiona has worked as a nutrition specialist and dietitian since 2020, focusing on metabolic and hormonal balancing. MicroRNA-155 is induced during the macrophage inflammatory response. If a mother is too sick to feed her infant at the breast, if possible, expressed breast milk should be fed to the infant by a healthy caregiver who does not have flu.

Expressing when you would normally breastfeed will also keep your milk supply steady. The thick yellowish milk (colostrum) produced for the first few days following birth is particularly rich in antibodies. She performed experiments noted in the review, analysis of the data as well as contributing to the writing and editing of the review. Transfer of maternal immune cells by breastfeeding:

It just makes me wonder WHY I can’t seem to get over this crap. A cold can be a sign of a healthy immune system. The composition of breastmilk affects flavours as well. Ever since I can remember I had this idea that breastfeeding was what loving moms do—and that it was the most natural thing in the world. In fact, the HIV-infected CD4+ T cells in breast milk are 17 times more effective than in blood (35). Most recently, specific HMOs, namely, 2′ and 3′ fucosylactose (2′FL and 3′FL, respectively) have been shown to structurally mimic histo-blood group aantigens, and thus block norovirus from binding to this surrogate (84).

These antibodies consist of two joined IgA molecules and a so-called secretory component that seems to shield the antibody molecules from being degraded by the gastric acid and digestive enzymes in the stomach and intestines. So it was kind of a shock when the nurse put my amazing tiny son in my arms and he had no interest whatsoever in the meal in front of him. Because breast milk supply could decrease for some mothers while they are ill, mothers may need additional lactation support from a lactation provider to address milk supply concerns, reduce the possibility of developing a breast infection, and support the breastfeeding relationship during this time. This protects babies from infections at a time when their own immune system is still immature. By the time you feel well enough to hold your baby after an operation, the amount of anaesthetic in your breast milk will be minimal and it should nearly always be safe to 10 breastfeed.

They consist of white blood cells, or leukocytes, that fight infection themselves and activate other defense mechanisms. Ear infections and allergies occur more commonly in babies who are not breastfed. Interestingly, sTLR2 levels were significantly increased in HIV-infected compared with uninfected breast milk samples, and significantly correlated with p24 [a marker of viremia (151)] and IL-15 concentrations (55).

“We need a place where we can have a much more honest communication in understanding the true, actual benefits of breastfeeding,” she says—because “if we’re overstating it, we’re over-prescribing it. The first way for a baby to acquire immunity is called passive immunity, and it occurs during pregnancy. Interestingly, secretory IgA can probably protect mucosal surfaces other than those in the gut.

A survey of US women (pdf) conducted in 2020 showed that the main motivation behind their decision to breastfeed is the belief that it is better for their child’s health. Protective agents in breast milk include antibodies and a mix of proteins, such as lactoferrin and lysozyme, which have strong antibacterial properties. They are part of the first line of defense against pathogen invasion and trigger innate immune responses and subsequent antigen-specific adaptive immunity. Unexpectedly, this effect was passed onto the infants by cells in the mother's milk and not proteins such as antibodies.

For breast cancer, nursing for at least a year appears to have the most protective effect. Human milk cells contain numerous miRNAs that may change with milk removal and regulate multiple physiological processes. For instance, by contrast to the two major T cell subsets found in the periphery, milk T lymphocytes almost exclusively comprise an extralymphoid cell population in which most CD4and CD8T cells are effector memory cells []. Additionally, all pieces of equipment and nonsterile supplies, such as blood pressure cuffs, can harbor and spread hospital and healthcare acquired infections.
