Immune checkpoint inhibitor (ICI) treatment reduced levels of estrogen and important heart-protective proteins, researchers reported in the Nov. 2, 2022, online edition of Science Translational Medicine. Hormone therapies could target this endocrine-cardiac-immune pathway and mitigate myocarditis risk without affecting treatment responses.
Cancer-associated fibroblasts (CAF) expressing the LRRC15 protein (leucine-rich repeat-containing protein 15) could be responsible for the suppression of antitumor immunity, according to a study using mouse models of pancreatic cancer. Scientists from Roche Holding AG subsidiary Genentech Inc. demonstrated in vivo that TGF-β type 2 receptor signaling in healthy universal fibroblasts produces cancer-associated LRRC15+ myofibroblasts.
The checkpoint molecule CD47 has high hopes riding on it in oncology as being the innate immune equivalent of PD-1. Multiple companies are developing blockers against CD47 and/or its ligand, SIRPa, for the treatment of various tumors.
