Obesity leaves a lasting memory in immune cells

Obesity appears to leave a molecular imprint on key immune cells that may persist for 5 to 10 years after weight loss. This long-lasting “obesity memory” could help explain why…

Immune cells flood into the aging brain, Stanford scientists discover

Scientists have discovered that the aging human brain may be far less isolated from the rest of the body than once believed. Stanford researchers found that large numbers of immune…

Stanford scientists discover immune cells that explode like microscopic bombs

Stanford researchers discovered immune cells in flatworms that explode within minutes, killing nearby bacteria and foreign cells before vanishing completely. Their unusually fast and localized attack could offer clues for…

A simple supplement could help the immune system fight cancer and viruses

Low arginine levels may allow cancer cells and viruses to slip past the immune system by reducing production of a crucial cellular warning protein. In mice, arginine-rich diets led to…

A single sauna session sends immune cells surging

A single 30-minute sauna session may briefly put the immune system on higher alert. Finnish researchers found that sauna heat, paired with a short cold shower, increased every type of…

A hidden immune backup system could supercharge mRNA cancer vaccines

Researchers found that mRNA cancer vaccines can recruit an unexpected immune cell to launch powerful tumor-fighting responses, overturning a long-held assumption about how the vaccines work. The discovery could lead…
