WitrynaWhile CD40 ligation enhanced Fas-mediated apoptosis, stimulation with anti-IgM and IL-4 partially protected CD40L-activated B cells from Fas-mediated apoptosis. It was found that bcl-xL gene expression in normal splenic B cells was induced drastically by treatment with anti-IgM and IL-4, but not CD40L. Witryna7 sty 1997 · The CD10 − IgM + B cells alone did not produce Ig, irrespective of whether T-cell-derived cytokines were supplied or not. However, when cultured together with autologous bone marrow T cells and T-cell-derived cytokines, IgM was produced in levels ranging from 0.4 to 23.6 μg/ml (12.0 ± 9.6 μg/ml). on clouds for nursing
