rag-1 and rag-2: Biochemistry and Protein Interactions

In the vertebrate immune system, each antibody is customized to attack one particular antigen (foreign proteins and carbohydrates) without attacking the body itself. The human genome has at most 30,000 genes, and yet it generates millions of different antibodies, which allows it to be able to respond to invasion from millions of different antigens. The immune system generates this diversity of antibodies by shuffling, cutting and recombining a few hundred genes (the VDJ gene… WebThe inhibitory function of Treg cells of Tg mice was equal to that of wild-type mice in vitro.
