Enhancing outcomes in medically inoperable early-stage NSCLC with gut-targeted antibiotics and stereotactic body radiotherapy: results from a randomized pilot study.

Background: Gut microbiota modulation is an emerging strategy to improve cancer therapy outcomes. This study evaluated the safety and therapeutic potential of combining oral vancomycin-a non-absorbed, gut-restricted antibiotic with primary activity against gram-positive bacteria-with stereotactic body radiotherapy (SBRT) in early-stage non-small cell lung cancer (NSCLC). The underlying hypothesis was that vancomycin-induced changes in gut microbiota could enhance the antitumor effects of SBRT.

The Glucose Transporter 5 Enhances CAR-T Cell Metabolic Function and Anti-tumour Durability.

Activated T cells undergo a metabolic shift to aerobic glycolysis to support the energetic demands of proliferation, differentiation, and cytolytic function. Transmembrane glucose flux is facilitated by glucose transporters (GLUT) that play a vital role in T cell metabolic reprogramming and anti-tumour function. GLUT isoforms are regulated at the level of expression and subcellular distribution.
