Potatoes and other starchy vegetables, which are some of the major sources of vitamin B6 for Americans. Their function is to memorize the characteristics of the antigen that activated their parent B cell during initial infection such that if the memory B cell later encounters the same antigen, it triggers an accelerated and robust secondary immune response. Prikaži več In immunology, a memory B cell (MBC) is a type of B lymphocyte that forms part of the adaptive immune system. These cells develop within germinal centers of the secondary lymphoid organs. Memory B cells circulate in … Prikaži več T cell dependent mechanisms In a T-cell dependent development pathway, naïve follicular B cells are activated by antigen presenting Prikaži več The memory B cells produced during the primary immune response are specific to the antigen involved during the first exposure. In a secondary response, the memory B cells specific to the antigen or similar antigens will respond.
