Abstract:
:Blockade of immune checkpoint molecules, a group of molecules normally involved in maintaining self-tolerance and limiting T cell responses, has emerged as a breakthrough in cancer therapy. Two recent studies published in Science show that, in mice, gut commensal microbes promote antitumor immunity and may determine therapy efficacy.
