The importance of the intracytoplasmic domain of CD3 epsilon in thymocyte development /Li, Samantha. January 2009 (has links)
The development of T cells in the thymus is a tightly regulated process. Any defect in thymic differentiation could result in autoimmune disorders, inability to ward off infections or neoplasm. Early thymocyte development requires signals mediated through the preTCR complex by the associated CD3 chains (gamma, delta, epsilon, and zeta). Research conducted towards this project has revealed that signaling modules within the intracytoplasmic domain of CD3epsilon is absolutely required for this process. Interestingly, our results emphasized the importance of the proline-rich sequence motif in preTCR mediated signaling events, such as the proliferation of double negative thymocytes and the regulation of TCR surface expression on double positive thymocytes in a stage-specific manner. The outcomes of this project may provide a better understanding of the mechanism of preTCR-mediated thymocyte differentiation and the role of CD3 chains in these processes.
