Webcation and posttransplant longevity of organs. Antibodies originate from plasma cells (PCs), which are terminally differentiated B cells. Long-term production and persistence of these antibodies is partly due to fast … Web1 de out. de 2024 · Plasma cells are generally considered to be post-mitotic, or at least believed to divide very infrequently 4, and a subset of plasma cells have the capacity to be extremely long-lived 5-7 (Fig. 1). The canonical plasma cell derives from follicular B cells via the germinal center, although all mature B-cell subsets and activation routes (T-cell … Plasma cells (PC) represent an essential arm in humoral immunity as the main line of defense against infection and re-infection. As the primary producers of circulating immunoglobulin (Ig), these cells provide vital durable and protective immunity against a multitude of pathogens. Longitudinal analysis of antigen-specific … Ver mais There has been considerable research into the biology of PC as a whole, from how they are generated and the key transcriptional … Ver mais It was originally proposed that sustained antibody responses resulted from constant replenishment of a SLPC pool by continuous memory B cell re-stimulation (35).
