The Role of Socs1 in the Immune Response

Abstract

T cells are a central component of the immune system and without T cells the body is very vulnerable to infections. One subgroup of T cells is the killer T cells that are important for identifying and killing cells infected by viruses and bacteria. The immune system works to maintain T cell numbers at a fairly constant level and part of this process includes sending signals to the killer T cells from other cells via cell surface protein interactions and soluble mediators, such as cytokines. We have been studying killer T cells, which are missing a protein SOCS1. SOCS1 is important for switching off the signals generated by a group of cytokines. As a consequence of being unable to correctly r..
