Negative Selection during the Peripheral Immune Response to Antigen
27 Dec 2000
Abstract excerpt
Thymic selection depends on positive and negative selective mechanisms based on the avidity of T cell interaction with antigen-major histocompatibility complex complexes. However, peripheral mechanisms for the recruitment and clonal expansion of the responding T cell repertoire remain obscure. Here we provide evidence for an avidity-based model of peripheral T cell clonal expansion in response to antigenic...
