WebFeb 15, 2008 · Abstract CD40-activated B (CD40-B) cells might be an attractive source of autologous antigen-presenting cells (APCs) for immunotherapy due to the ability to obtain them from peripheral blood and expand them in vitro. However, soluble IL-4 (sIL-4) in B-cell culture may not represent the "immunological synapse" between B and CD4+ T cells. WebB cells activated by antigen (also termed B lymphoblasts) are capable of rapid proliferation, immunoglobulin class-switch recombination, and differentiation into short-lived plasmablasts that express high levels of IRF4 and X-box-binding protein 1 (XBP1), and intermediate (mid) levels of B lymphocyte-induced maturation protein 1 (BLIMP1) and … sheridan motor cdjr
