Intratumoral cancer immunotherapy exploiting anti-viral immunity.

ABSTRACT: After a long period of endeavor, immunotherapy has become the mainstream of cancer therapies. This success is mostly ascribed to immune checkpoint blockade, chimeric antigen receptor-transduced T cell therapies, and bispecific antibodies. However, these methods have been effective or applicable to only a limited proportion of patients so far. Thus, further development of broadly applicable and effective immunotherapies is eagerly anticipated. Given that innate immunity is key to the induction of robust adaptive immunity and that the immunosuppressive tumor microenvironment is a major hurdle to overcome, intratumoral immunotherapy in which delivery of immunostimulatory microbial agents to the tumor site triggers innate immunity in situ is a rational strategy. There has been a plethora of pr
