WebHow are memories formed in the brain? The brain simmers with activity. Different groups of neurons (nerve cells), responsible for different thoughts or perceptions, drift in and out of action. Memory is the reactivation of a specific group of neurons, formed from persistent changes in the strength of connections between neurons. 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 the blood stream in a quiescent state, sometimes for decades. Their function is to … Meer weergeven T cell dependent mechanisms In a T-cell dependent development pathway, naïve follicular B cells are activated by antigen presenting follicular B helper T cells (TFH) during the initial infection, or … Meer weergeven Upon infection with a pathogen, many B cells will differentiate into the plasma cells, also called effector B cells, which produce a first wave of protective antibodies and help clear infection. Plasma cells secrete antibodies specific for the pathogens but they cannot … Meer weergeven Memory B cells are typically distinguished by the cell surface marker CD27, although some subsets do not express CD27. Memory B … Meer weergeven Vaccines are based on the notion of immunological memory. The preventative injection of a non-pathogenic antigen into the organism allows the body to generate a durable immunological memory. The injection of the antigen leads to an antibody … Meer weergeven 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 … Meer weergeven Memory B cells can survive for decades, which gives them the capacity to respond to multiple exposures to the same antigen.
