title: Is antigen specificity of autoreactive T cells the key to islet entry?
abstract: It has been widely hypothesized that pancreatic islet infiltrates include both islet-antigen-specific and nonspecific T cells. In this issue of Immunity, Lennon et al. (2009) demonstrate that islet-antigen specificity is required for accumulation in the islets.
