title: T cell receptor specificity and mimotopes.
abstract: Degeneracy rather than unique ligand specificity seems to guide T cell functions. This view has evolved from analyses of T cell development and responses in vivo, as well as studies with synthetic molecular libraries in vitro, and has opened new prospects both for understanding T cell biology and for applied immunology.
