Abstract:In colorectal carcinoma (CRC), a Th1-tumor microenvironment (TME) is associated with improved prognosis of the patients. The lead cytokine of the Th1-response is interferon (IFN)-γ. IFN-γ is predominantly regarded as an immunomodulatory cytokine. At present, its putative tumor blood vessel-directed anti-tumorigenic effects have not been investigated comprehensively. We demonstrate that the vascular effects of IFN-γ in CRC trigger a two-step anti-tumorigenic chain reaction. First, IFN-γ exerts direct angiostati… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
