Maternal inheritance of the immune system

Abstract

The immune system contains the guardians of our body, which are considered cells and molecules that work together to create defense mechanisms that participate in critical stages of development, such as pregnancy and lactation. During pregnancy, physiological changes in the mother arise that impact the development of the fetus's immune system. This is relevant because it generates essential protection at a stage vulnerable to infections. Another factor that influences the protection of the immune system is the form of birth, which is crucial for the acquisition of the baby's microbiota, contributing to the formation of the immune system to defend against pathogens and harmful substances in the first months of life. This is why breastfeeding plays a vital role by providing antibodies and nutrients that aid in the maturation of babies' immune systems.
