Role Of Cbl-Family Ubiquitin Ligases As Critical Negative Regulators Of T Cell Activation And Functions, Benjamin Goetz

Theses & Dissertations

Adaptive T cell immunity is essential for defense against foreign antigens and immune surveillance against cancer. Tight regulation of T cell activation is required to avoid autoimmunity to self-antigens or protracted inflammation after foreign antigens are cleared. Incomplete or inappropriate stimulation leads to an active shutdown of T cell activation called anergy. The Casitas B-lineage Lymphoma (CBL)-family of ubiquitin ligases (E3s) are essential negative regulators of T cell activation that impinge on thymic selection as well as anergy induction programs. Single gene studies show that CBL is critical during T cell development while CBL-B plays an essential role in ...
