Delivery of Oncolytic Reovirus by Cell Carriers.

Oncolytic virus therapy is a rapidly expanding branch of cancer immunotherapy and represents a genuine opportunity to improve currently available treatment options. However, as single agents oncolytic viruses have shown only moderate clinical benefit and many challenges remain before their full potential is realized. Central to this is the efficient delivery of the virus to the tumor site and potentiation of the antitumor immune response. This chapter describes the loading of oncolytic reovirus onto monocytes which act as carriers for delivery of the virus to the tumor site and, as antigen presenting cells, may also thereby potentiate the development of an adaptive antitumor immune response.
