Which one of the following B cell responses is NOT stimulated by CD40 ligand?

Question

Quizplus · Accepted Answer

CD40 ligand binding to B cell CD40 enhances production of secreted,not membrane,Ig.CD40 signaling involves recruitment of signaling intermediates,called tumor necrosis factor-receptor associated factors (TRAFs),to the cytoplasmic tails of CD40 and the downstream activation of NF-$\kappa$B,as well as other transcription factors.The signaling cascades result in increased expression of various genes,including B7 costimulators,and increased Ig isotype switching,which is mediated by switch recombinases.
