Abstract

The proposed research is aimed at defining fundamental mechanisms responsible for the development and function of the CD4 T-cell subset. We propose studies to define the mechanisms of intrathymic commitment to the CD4 lineage, alternative signalling pathways coupled to TCR ligation of CD4 cells by superantigen or conventional antigen and the role of the CD4 molecule in regulating the response of these cells to TCR ligation.
