Definition 1

Those manifestations of the immune response which are mediated by antigen-sensitized T-lymphocytes via lymphokines or direct cytotoxicity. This takes place in the absence of circulating antibody or where antibody plays a subordinate role. (NCI Thesaurus)

Definition 2

immunity mediated by T-lymphocytes through either release of lymphokines or exertion of direct cytotoxicity; responsible for reactions such as allograft rejection and delayed hypersensitivity. (NIH CRISP Thesaurus)
