WebPlasma cells are terminally differentiated cells which are derived from antigenically stimulated B lymphocytes.127 During their lifespan of 2–3 days they continuously synthesize and secrete antibodies that have specificity for the particular antigen that stimulated the plasma cell precursor to proliferate and differentiate. WebSome investigators show that LLPCs can be generated independently of B cell maturation (i.e., in the absence of GC formation) ( 30 – 32 ). However, these studies showed persistence of ASCs for only 3–4 months and it is unclear if they are indeed long-lived. 16 振込手数料Unlike their precursors, plasma cells cannot switch antibody classes, cannot act as antigen-presenting cells because they no longer display MHC-II, and do not take up antigen because they no longer display significant quantities of immunoglobulin on the cell surface. However, continued exposure to antigen through those low levels of immunoglobulin is important, as it partly determines the cell's lifespan. 16 式機動戦闘車
