Memory B cell - Wikipedia
In immunology, a memory B cell (MBC) is a type of B lymphocyte that forms part of the adaptive immune system. These cells develop within germinal centers of the secondary lymphoid organs. Memory B cells circulate in the blood stream in a quiescent state, sometimes for decades. [1]

Feb 1, 2023 · B cells produce antibodies that destroy antigens or the pathogen associated with a particular antigen. B cells can also remember specific antigens so your immune system can launch an effective defense if the pathogen ever enters your body again. How do B cells work in the immune system?

Human memory B cells originate from three distinct germinal …
A substantial fraction of B cells in blood of human subjects has experienced antigen and shows hallmarks of memory B cells: SHMs of rearranged Ig genes and fast recall responses to antigen. 13 Initially, human memory B cells were identified based on the expression of CD27. 14,15 IgA and IgG class-switched CD27 + B cells are derived from T cell ...
Immunological memory cells - PMC - PubMed Central (PMC)
This article reviews immunological memory cells, currently represented by T and B lymphocytes and natural killer (NK) cells, which determine a rapid and effective response against a second encounter with the same antigen. Among T lymphocytes, ...
Memory B cells and plasma cells: The differentiative continuum …
Memory B cells are a critical reservoir for plasma cell generation in the secondary response. Identification of memory B cells requires that they be distinguished from naïve, activated, and germinal center precursors and from plasma cells.
The essential roles of memory B cells in the pathogenesis of
Abstract. Emerging evidence indicates that memory B cells are dysfunctional in systemic lupus erythematosus (SLE). They are hyporesponsive to signalling through the B cell receptor (BCR) but retain responsiveness to Toll-like receptor (TLR) and type I interferon signalling, as well as to T cell-mediated activation via CD40-CD154.
