What is the name of breast milk antibodies?

Understanding Breast Milk Antibodies
Breast milk is often hailed as a miraculous substance, not just for its nutritional value but also for its role in bolstering an infant’s immune system. Central to this protective function are antibodies, specifically known as immunoglobulins. These antibodies are crucial for providing passive immunity to newborns, who are born with an immature immune system.
Types of Antibodies in Breast Milk
The primary antibodies found in breast milk include IgA, IgM, and IgG. Among these, secretory IgA (SIgA) plays a particularly vital role. This form of IgA is specially adapted to function in mucosal areas, forming a protective layer in the infant’s gastrointestinal tract, as well as in the nose and throat. This barrier helps prevent pathogens from entering the body, effectively acting as the infant’s “first line of defense” against infections .
Colostrum, the first milk produced after childbirth, is especially rich in these antibodies. It contains a high concentration of SIgA, which is essential for protecting newborns during their early days of life when their immune systems are still developing. In addition to SIgA, breast milk also contains other immunoglobulins like IgM and IgG, which contribute to the overall immune protection.
The Importance of Antibodies
The transfer of these antibodies from mother to child is a critical aspect of breastfeeding. As infants consume breast milk, they receive not only essential nutrients but also a robust supply of antibodies that help shield them from infections and diseases. This maternal immunity is particularly important in the early months of life, as it helps to bridge the gap until the infant’s own immune system matures and can produce its own antibodies.
In summary, the antibodies present in breast milk, particularly secretory IgA, are fundamental to providing newborns with the necessary immune support to thrive in their new environment. This unique aspect of breastfeeding underscores the importance of maternal health and nutrition during pregnancy and lactation, as it directly impacts the well-being of the infant.

Which type of immunity results from antibodies ingested from breastmilk?

Breastfeeding provides passive and likely long-lasting active immunity.

What antibodies are most abundant in breast milk?

The most abundant immunoglobulin in human milk is SIgA, which represents over 90% of milk antibodies. However, immunoglobulins G and M (IgM) are also present, but in concentrations much lower than SIgA (9–13).

Is immunoglobulin safe for breastfeeding?

It is considered safe for use during pregnancy and breastfeeding. IVIG is used for many autoimmune conditions such as Kawasaki’s disease in children, dermatomyositis, polymyositis, and juvenile dermatomyositis, systemic lupus erythematosus.

What antibodies are passed from mother to baby?

This elicits immunoglobin G (IgG) antibodies, which are passed through the placenta from the parental bloodstream and are secreted into the colostrum and milk that are transferred to the infant via breastfeeding. Maternal antibodies help protect the infant at birth and over the next few months.

Which antibody is found in milk?

Immunoglobulin A is the major immunoglobulin in human colostrum and milk (Figure 1), however it is also present in milk of most other species.

What is antibody rich milk called?

Colostrum or “first milk” is produced in the initial secretions of the mammary gland following the birth of offspring. Colostrum is most commonly distinguished from whole milk because it contains high concentrations of immunoglobulins (Ig), otherwise known as antibodies.

What is the most common immunoglobulin in breast milk?

The most abundant immunoglobulin in human milk is SIgA, which represents over 90% of milk antibodies. However, immunoglobulins G and M (IgM) are also present, but in concentrations much lower than SIgA (9–13).

What are IgG antibodies?

Immunoglobulin G (IgG): This is the most common antibody. It’s in blood and other body fluids, and protects against bacterial and viral infections. IgG can take time to form after an infection or immunization.

What type of antibodies are in breast milk?

Of note, immune cells such as B and T lymphocytes, regulatory cells, monocytes/macrophages, neutrophils, natural killer cells and IgA, IgG and IgM antibodies are found in the breast milk (7).

What type of immunity is provided by breast milk?

Breast milk’s natural probiotics for a healthy microbiome
These useful bacteria strengthen your child’s immune response by offsetting the growth of unfriendly organisms that can cause infections and inflammation. Breastfeeding gives your baby a steady supply of probiotics, strengthening their gut microbiome.
