Both the pre-BCR and the IL-7Rα are essential for expansion at the pre-BII cell stagein vivo
24 May 2005
Abstract excerpt
During B cell development, proliferative expansion takes place after expression of the pre-BCR. At this pre-BII cell stage, the IL-7Ralpha is also expressed. Some in vitro studies suggest that pre-BCR-dependent expansion relies on the IL-7Ralpha, and others that it does not. It has also been suggested that the pre-BCR mediates down-regulation of the IL-7Ralpha. However, the in vivo relationship between the...
