Article Synopsis
- Many patients treated with FDA-approved CAR T cells see their disease progress, especially with solid cancers and certain types of blood cancers like T cell lymphomas.
- A major challenge in adoptive T cell therapies is the dysfunction of CAR T cells, which struggle to expand and last after being infused.
- The study reveals that knocking out the CD5 gene using CRISPR-Cas9 can improve the antitumor abilities of CAR T cells by enhancing their function and persistence, suggesting CD5 as a key target for improving T cell therapies.
Article Synopsis
- Studies highlight the role of gut microbes in enhancing T cell function during cancer checkpoint immunotherapy.
- This research indicates that vancomycin-induced changes in gut microbiota improve the effectiveness of CAR T cell therapy in mice with lymphoma and melanoma.
- Clinical observations reveal that leukemia patients receiving CART-19 therapy while on vancomycin had a stronger therapeutic response, suggesting gut microbiota modulation could enhance CAR T cell treatment outcomes across different cancers.
Activating RAS missense mutations are among the most prevalent genomic alterations observed in human cancers and drive oncogenesis in the three most lethal tumor types. Emerging evidence suggests mutant KRAS (mKRAS) may be targeted immunologically, but mKRAS epitopes remain poorly defined. Here we employ a multi-omics approach to characterize HLA class I-restricted mKRAS epitopes.

A subset of patients treated with chimeric antigen receptor (CAR) T cells or bispecific T cell engager (BiTE) antibodies display severe neurotoxicity, including fatal cerebral edema associated with T cell infiltration into the brain. Here, we report that mural cells, which surround the endothelium and are critical for blood-brain-barrier integrity, express CD19.

APPROACH AND RESULTS: mice were crossed into (low-density lipoprotein receptor knock out) mice. Double knockout (dKO) mice had increased plaque burden in aortic arch and root compared with controls after 14 weeks of high-fat diet (HFD).
