The T cell repertoire in a healthy adult is shaped by thymic selection (positive and negative), where naive CD4+ and CD8+ T cells can then interact, and be primed, with “foreign” antigen in the secondary lymphoid tissues; Antigen engagement via the T cell receptor (TCR) then shapes the repertoire of antigen-specific T cells and most likely the functional attributes of the T cell • TD: involves protein antigens and CD4+ helper T cells – 1) Multivalent antigen binds and crosslinks membrane Ig receptors – 2) Activated T cell binds B cell thru antigen receptor and via CD40L (T)/CD40 (B) interaction • TI: involves multivalent or highly polymerized antigens, does not require T cell help – TI-1: e.g., LPS.
