Two types: B and T. Both produced in the bone marrow. B matures in the bone marrow. T matures in the thymus. Immunocompetency. B and T lymphocytes must recognize “self.”. Chapter 4. Introduction. Molecules recognized as “non-self” are antigens. Several mechanisms to protect itself . First level of protection include physical and biochemical-skin, acid in stomach. Second level of protection phagocytic cells, enzymes, and proteins. The relationship between viruses and the immune system is much more intimate than it is for most bacteria: viruses often modify the cells within which they replicate, thereby rendering them ‘foreign’ and susceptible to attack by sensitized lymphocytes; furthermore, . The Immune System. The immune system is a group of cells & soluble molecules, which interact & distinguish patterns in the body as “self” or “non-self,” in order to eliminate those that are “non-self.”. Immunological unresponsiveness to self is referred to as . tolerance. or . self-tolerance. Very important to human health. How is this achieved?. -cells with receptors for self-antigens are destroyed in the thymus or bone marrow (central tolerance). Mastitis Mastitis is inammation of the breast tissue that can be caused by an engorged breast or a blocked duct. A red, lumpy, painful area on the breast is an early sign and mastitis can de A.
