Description

The main objective of this renewal application is to define, at the
molecular level, the antigenic sites on SV40 T antigen recognized
by the cytotoxic T lymphocytes (CTL) in association with self coded
major histocompatibility complex class I or class II glycoproteins.
We have identified at least three distinct CTL recognition sites
in the amino terminal half and one site in the carboxy terminal
half of SV40 T antigen. Using CTL clones and SV40 deletion
mutants, we are now proposing to, (1) determine the identify of
amino acids in CTL recognition sites on T antigen and the influence
of amino acids within the sites on CTL recognition in association
with H-2 antigens; (2) analyses of antigenic loss variants that
have escaped CTL mediated lysis for alteration in SV40 T antigen
CTL recognition antigenic sites; (4) investigate the nature of T
antigen recognized by CTL; and (5) study the contribution of
individual antigenic sites to CTL mediated response. The approach
utilized here will allow us to relate the role of SV40 T antigen
in transformation and in inducing a CTL immune response to the
antigenic sites on SV40 T antigen in the host undergoing
oncogenesis.
