Use of mTOR inhibitors to enhance T cell immune responses

摘要

It is disclosed herein that treatment of a subject with an mTOR inhibitor enhances antigen-specific T cell immune responses. Thus, provided herein is a method of enhancing an antigen-specific T cell response in a subject by administering to the subject a therapeutically effective amount of an mTOR inhibitor. The antigen can be any antigen, such as an antigen from a pathogen or a vaccine, or a tumor antigen. In some embodiments, the method further comprises administering to the subject a vaccine, such as a virus vaccine or a cancer vaccine. The mTOR inhibitor can be administered either before or after vaccination to enhance the quantity and quality of the T cell immune response and immunological memory. In some examples, the mTOR inhibitor is rapamycin or a rapamycin analog.
