WebNov 13, 2024 · These memory B cells can undergo more rounds of GC reaction to increase their antigen (Ag) affinity and to switch to IgG1 or IgE. Direct or sequential CSR produces membrane IgE + lymphocytes with different Ag affinity, and IgE B cell receptor (BCR) seems to induce a common, short-lived fate. WebSep 17, 2002 · Litinskiy et al. describe a mechanism for CSR that does not require T cell-B cell interaction. Cultured B cells stimulated with exogenous BLyS or APRIL underwent CSR, as detected by small amounts of switch circle DNA, an extrachromosomal product of CSR, and the expression of transcripts from this event. The addition of BLyS or APRIL …
