Splet01. okt. 2024 · The lineage of B cells impacts on the anatomical location, the diversity of the B-cell receptor expressed and the type of antigen typically encountered. ASCs are conventionally classified as either plasmablasts or plasma cells. Plasmablasts are short-lived, cycling cells that are produced in large numbers early in an immune response. SpletAs B cells differentiate into antibody-secreting cells (ASCs), short-lived plasmablasts (SLPBs) are produced by a primary extrafollicular response, followed by the generation of …

SpletAfter antigen recognition, naive B cells become activated and either develop into short-lived plasma cells secreting antigen-specific antibody, or enter a germinal center (GC) reaction where antigen binding is further optimized by hypermutation of the immunoglobulin genes and affinity maturation.

Activation of naïve B cells by vaccine antigens leads to a series of events which ultimately result in the production of memory B cells and differentiation into two classes of antibody secreting cells, short-lived plasmablasts and long-lived plasma …

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. chemim beach wearSpletPlasmablasts leave the germinal center and terminally differentiate into non-dividing plasma cells (also known as antibody-secreting cells, or ASC), which are specialized to produce vast quantities of single isotype antibodies (reviewed in Refs [32,33]).
