A special program developed by the University of California Health system and adopted at all six UC academic medical centers has been effective in reducing hypertension in patients and could be used by other health systems looking to standardize chronic disease care.

Forty-four UC San Francisco scientists have been named to the annual list of most “Highly Cited Researchers” for 2025 by the analytics company Clarivate.

Why are the elderly so much more likely to get sick and hospitalized for pneumonia and COVID? UCSF scientists found that old lung cells overreact to infections, inviting immune attack and runaway inflammation.

A new study traces the molecular pathway connecting the gut immune system to the brain during a parasitic infection, explaining how the immune system triggers a loss of appetite.

TRPM8, a key cold-sensing protein in nerve cells, activates to send “cold” signals to the brain when exposed to low temperatures or cooling sensations like menthol. New research from UCSF reveals how TRPM8 changes shape in response to cold, offering insights into cold sensitivity, pain conditions, and why birds are less sensitive to cold than mammals.
