B cells that expressed a constellation of checkpoint inhibitors could be spurred into antitumor activity by deleting or blocking the checkpoint molecule T-cell immunoglobulin and mucin domain 1 (TIM-1). The findings, which were published online in Nature on June 21, 2023, suggest ways to bring B cells into the antitumor fight. More broadly, Lloyd Bod told BioWorld, his laboratory aims to “break the dogma that B cells only produce antibodies.”
Differences in the immune reactions between smokers and nonsmokers may explain why only 20% of patients with lung cancer respond to immunotherapy treatment. Understanding these differences in the evolution of lung cancer between smokers and nonsmokers could be the key to unlocking new treatments.
The largest study to date on hypermutated gliomas has delivered new insights into their origin, as well as their response to several different treatments. Specifically, even though they are hypermutated, such tumors are unlikely to respond to PD-1 blockers.
