Regulating B-cell activation and survival in response to TLR signals

Following encounters with microbes, cellular activation programs that involve the control of proliferation and survival are initiated in follicular B cells either via the B-cell receptor in a specific antigen-defined manner, or through Toll-like receptors (TLRs) that recognize specific microbial products. This review summarizes and discusses recent findings that shed light on how the nuclear factor kappa B pathway controls and coordinates B-cell division and survival following TLR4 engagement.
