Our lab studies various aspects of B cell development. My project focuses on which signals may be mediating the survival and selection of immature B cells in the bone marrow. We are investigating whether signaling events through non-autoreactive B cell antigen receptors (BCRs) and cytokine receptors cooperate to control the lifespan of these cells. We hypothesize that tonic signals through non-autoreactive BCRs alter the expression of cytokine receptors on immature B cells, and the combination of survival signals through these receptors allow non-autoreactive immature B cells to continue development and enter the peripheral population.
