| Outline of Final Research Achievements |
Inflammatory Bowel Disease (IBD) is characterized by unrestrained lymphocyte activation that results in the production of a variety of pro-inflammatory cytokines and other mediators. Understanding the mechanisms of lymphocyte regulation is therefore of significant importance to dysregulated mucosal inflammation such as IBD. An area that is of significant interest is the cell autonomous mechanisms of T cell regulation through proteins that have natural inhibitory functions when expressed on T lymphocytes. In this regard, we have observed that CD66a has the general property of negatively regulating T cell responses initiated by antigen presentation. Defining the mechanisms of CD66a-mediated T cell regulation will lead to a significant understanding of the manner in which manipulation of this molecule may provide insights into novel therapeutic methods for the treatment of IBD.
