WebMemory B cells can scavenge for very low concentrations of antigen in a secondary response because _____. affinity maturation has already made their receptors fine-tuned for binding the antigen. What events occur as a result of memory B cells being activated as part of the secondary response? - Proliferation - A second round of affinity maturation 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 … See more 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 primary See more 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. … See more Memory B cells can survive for decades, which gives them the capacity to respond to multiple exposures to the same antigen. The long-lasting … See more Germinal center independent memory B cells This subset of cells differentiates from activated B cells … See more 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 … See more Memory B cells are typically distinguished by the cell surface marker CD27, although some subsets do not express CD27. Memory B cells that lack CD27 are generally … See more 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 response … See more
WebMemory B cells have several unique features including long lifespan, high sensitivity to low doses of antigen, quick and robust proliferation, and rapid differentiation into plasma cells that produce high-affinity antibodies during the secondary response. CD27 is a marker for human memory B cells (Klein, Rajewsky, & Kuppers, 1998 ).
