Clonal deletion is an important mechanism for the elimination of autoreactive T cells, however, negative selection of thymocytes is imperfect. Here authors show that MHC-II-restricted thymocytes avoid negative selection via downregulation of the integrin CD103, altering intra-thymic trafficking and distribution in a way that favours their survival.
