Could SIRPA expression predict response to anti-PD-1 immunotherapy?

Abstract

Immune checkpoint inhibitors (ICIs) offer significant promise for patients with melanoma; however, many patients succumb to de novo or acquired ICI resistance. In this issue of Cancer Cell, Zhou et al. propose a mechanism for signal-regulatory protein α1 (SIRPα) expression and describe how its loss may contribute to immunotherapy resistance.
