One treatment improves vaccine response
Those with aging immune systems struggle to fight off novel viruses and respond weakly to vaccination. Stanford Medicine researchers were able to revitalize the immune system in mice.
-
Gene fingerprint for brain aging
A study in mice finds that white matter — the tissue that transmits messages around the brain — shows the greatest changes as the animals age.

Antibody treatment rejuvenates stem cells
Old muscle stem cells express high levels of the cancer-associated molecule CD47. Blocking a pathway mediated by CD47 restored strength to old mice in a Stanford Medicine study.

Study reveals immune driver of brain aging
Scientists have identified a key factor in mental aging and shown that it might be prevented or reversed by fixing a glitch in the immune system’s front-line soldiers.

Molecule restores strength in old mice
A single protein is a master regulator of mouse muscle function during aging, a Stanford study finds. Blocking this protein increased muscle strength and endurance in old animals. It may play a role in age-related muscle weakening in humans.

Exercise rejuvenates stem cells of old mice
The researchers also identified a molecular pathway involved in turning back the clock on the cells. Drugs that could manipulate the pathway might be an effective substitute for exercise, they suggest.

Clues to how tiny fish ‘pauses’ life
Stanford scientists have identified molecular drivers that put the “pause” in “diapause,” a life stage of the African killifish that suspends its development as an embryo.

Protein helps speed wound healing
Pretreatment with a stem-cell-activating protein significantly enhances healing in mice, Stanford researchers say. The approach could eventually help people going into surgery or combat heal better from injuries they sustain.
