Targeting immunosuppression for cancer therapy

Cristina Ghirelli et al. J Clin Invest. 2013 Jun.

Abstract

Failing immunity has been acknowledged for its contribution to cancer development and progression. Recent clinical findings have provided payoffs for significant preclinical evaluation and refinement over the last 20 years, but many questions remain to be answered. In this issue of the JCI, Marabelle et al. describe a novel method for targeting the Tregs that infiltrate tumors, demonstrating that dampening the tumor immunosuppressive environment while activating innate antitumor immunity may be an effective approach to cancer treatment.

Figure 1
Figure 1. Marabelle et al. showed how local immunotherapy in mice helps the eradication of tumors at distant sites, even in an immune-privileged site such as the brain.
This study opens several questions, and how these findings may translate to human immunotherapy is still a matter of debate.
