Defective fat cells drive metabolic disease in lipodystrophy

Many people may have a dim view of their fat tissue, yet scientists have come to recognize adipose as a necessary and metabolically active organ, carrying out many vital functions within the body.

Tirzepatide shows dual benefits in sleep apnea trial improving metabolism and reducing inflammation

Tirzepatide significantly improved cardiometabolic risk markers in adults with obesity and moderate to severe obstructive sleep apnea in the SURMOUNT-OSA phase 3 trials. Mediation analyses suggest both weight loss and reduced sleep-disordered breathing contributed to improvements in inflammation, insulin resistance, lipids, and blood pressure.

Gut microbial butyrate enhances mucosal vaccine antibody responses

A research team from POSTECH and ImmunoBiome in Korea, led by Professor Sin-Hyeog Im, has uncovered a new mechanism showing how butyrate-a short-chain fatty acid produced by gut commensal bacteria-enhances T follicular helper (Tfh) cell activity to promote antibody production and strengthen mucosal vaccine efficacy.
