HIF1 protein linked to tendon pain

Researchers at ETH Zurich found that part of the HIF1 protein controls gene activity in tendon cells and can trigger tendinopathy. Experiments in mice and human tissue show HIF1 remodels collagen, makes tendons brittle and may cause pain.

New modular CAR-T system controls where and when cells attack

Researchers at the University of Chicago created GA1CAR, a modular CAR-T system that uses short-lived Fab fragments to guide and pause tumor targeting. In animal tests the same cells were redirected to different tumors and remained functional.

New drug pair helps fight rifampicin-resistant tuberculosis

Scientists paired rifampicin with a probe called AAP-SO2 that binds bacterial RNA polymerase at a different site and slows transcription. The pair killed resistant mutants in culture and was especially effective in a rabbit model.
