WebDec 13, 2002 · After stimulation with CpG or T cell help, a fraction of proliferating memory B cells acquired phenotypic markers characteristic of plasma cells, namely, loss of CD20 ( Fig. 2 A) and up-regulation of CD138, CD126, and CD38 ( 15 ). These cells also secreted IgM, IgG, and IgA at a high rate ( 14 ). WebCells that express TLR-9, which include plasmacytoid dendritic cells (PDCs) and B cells, produce Th1-like proinflammatory cytokines, interferons, and chemokines. Certain CpG motifs (CpG-A) are especially potent at activating NK cells and inducing IFN-α production by PDCs, while other motifs (CpG-B) are especially potent B cell activators.
