<p>Methods for generating antigen-specific cytotoxic T lymphocytes (CTLs) in vitro are presented in conjuntion with methods for using these CTLs for therapy in vivo. The antigen presenting cells (APCs) used herein notably include dentritic cells pretreated with GM-CSF and IL-4. Antigen-specific CTLs were obtained by incubating CD8 preparations in the presence of APCs that bound desired peptides. IL-7 was generally added at day 1 of the incubation; IL-10 was generally added one day later and during restimulation. The invention also comprises methods for using peptide pulsed dentritic cells to identify novel MHC Class I-restricted tumor antigens and subdominant epitopes.</p> |
