TNF-alpha blocks new neurons in hippocampus, reveals inflammation pathway

A groundbreaking King's College London study published in Nature Communications reveals that TNF-alpha, a molecule linked to chronic inflammation, disrupts the brain's ability to generate new neurons in the hippocampus. This discovery uncovers a critical pathway connecting long-term inflammation to cognitive decline in Alzheimer's disease, depression, aging, and post-viral neurological conditions. Understanding how TNF-alpha impairs neurogenesis offers promising therapeutic targets for treating neurodegenerative diseases and cognitive disorders. Researchers believe blocking this inflammatory pathway could restore the brain's regenerative capacity and slow cognitive deterioration in affected patients.
