Abstract
The E3 ubiquitin ligase Cbl-b acts as a key regulator of T cell activation and peripheral tolerance. Cbl-b deficiency uncouples the requirement of CD28 costimulation for T cell activation and exhibits resistance to T cell anergy and tolerance. Cbl-b−/− mice are highly susceptible to autoimmune diseases. Conversely, they mount a robust antitumor response resulting in spontaneous tumor rejection. Therefore, modulation of Cbl-b might provide a unique opportunity for immunotherapeutic strategies for inflammatory disorders, including autoimmunity and cancer.
