Although long identified in humans using CD27 as a pan-memory B cell marker, the existence of such cells in mice was difficult to prove. WebNSwM B cells consist of a type of memory B cells that have not undergone class switching.47–49 It seems that on antigen rechallenge NSwM B cells (CD19 +CD27+IgD+IgM+) enter the germinal centre (GC) in contrast to IgG +memory B cells which differentiate to plasma cells.49 NSwM B cell are low affinity memory B cells that retain an …
WebFor most mature B cells the key markers include IgM and CD19, a protein receptor for antigens (Kaminski DA. Front Immunol. 2012). Activated B cells express CD30, a regulator of apoptosis. Plasma B cells lose CD19 expression, but gain CD78, which is used to quantify these cells. Memory B cells can be immunophenotyped using CD20 and CD40 expression.
