LY341495, an mGluR2/3 Antagonist, Regulates the Immunosuppressive Function of Myeloid-Derived Suppressor Cells and Inhibits Melanoma Tumor Growth.

In this study, we found that the metabotropic glutamate receptor (mGluR) 2/3 was expressed on MDSCs, and an mGluR2/3 antagonist LY341495 attenuated the immunosuppressive activity of MDSCs. Furthermore, we observed that LY341495 treatment inhibited B16-F10 melanoma growth in vivo. Taken together, our data suggest that glutamate signaling promotes tumor growth by increasing the potency of immune suppression. PMID: 30504687 [PubMed - in process]
