Jump-starting the T cell response in established tumors. (PubMed, bioRxiv)
Consequently, investigators are testing checkpoint inhibitors in combination with drugs like the class I histone deacetylase inhibitor, entinostat (ENT)...However, by first "jump-starting" the T cell response using an oncolytic virus, the anti-tumor activity of ENT and PD1 blockade is restored. These data establish a general paradigm, independent of tumor type, to rationally manipulate anti-tumor immunity.
