SpletAfter activation with antigen (usually a TI antigen), MZ B cells cannot upregulate Bcl6 and hence these cells instantly proliferate and differentiate into short-lived IgM-secreting plasma cells without undertaking somatic hypermutation and isotype switching. SpletDuring the antigen-dependent phase of development, marginal zone B cells differentiate into short-lived plasma cells, while follicular B cells differentiate into short-lived plasma cells or take part in germinal center reactions in the spleen, lymph nodes, and mucosal –associated lymphoid tissue, where follicular B cells differentiate into ... togston parish councilSplet此时完成分化的B细胞离开GC，成为记忆B细胞(memory B cell)和长寿浆细胞(long-lived plasma cell)。体细胞超突变（SHM）除了上一章中提到的VDJ重组外，B细胞还可以通过体细胞超突变SHM产生更多多样性，这也是GC反应中提高抗体亲和力的重要过程。 togston house north togston

SpletUntil recently, the ability to distinguish types or compartments of plasma cells was poorly developed. Early studies using incorporation of nucleotide analogs to measure population turnover determined that there were short-lived and long-lived plasma cells that were unequally distributed amongst lymphoid tissues in that there was a preponderance of … Splet31. okt. 2024 · CD38 is a type II glycoprotein highly expressed on plasmablasts, short-lived and long-lived plasma cells, but weakly expressed on other lymphoid cells, myeloid cells and non-hematopoietic cells. This expression pattern makes CD38 an interesting target for a targeted therapy aiming to deplete antibody-producing plasma cells.
