WebThe frequency of polyreactivity in the normal adult human B cell repertoire has been estimated to be 4% of naïve B cells, 23% of IgG+ memory B cells, and 26% of intestinal IgA+ and IgG+ plasmablasts ( 27 – 29 ). On the other end of the spectrum, a mono reactive BCR is activated only when it encounters a single cognate antigen.
WebB cells specific for bacterial capsular polysaccharides are reported to be enriched in the spleen, and splenectomized patients are vulnerable to these bacteria ( 16, 17 ).
