3+ week, 2+ day ago   (415+ words) a fast cell-signaling process called ectodomain shedding -- rather than being newly produced and released...The findings suggest that exercise intensity may strongly influence the proteins and metabolites released...

1+ week, 3+ day ago   (1233+ words) Aging may be partly fueled by immune cells losing their ability to clear away damaged, inflammation-promoting cells. Blocking a single receptor restored that cleanup process in mice, reducing inflammation and helping their organs, muscles, and memory remain remarkably youthful....

6+ hour, 9+ min ago   (594+ words) Scientists discovered that aging cells can use malfunctioning mitochondria to unlock inflammatory genes and keep the immune system stuck in a prolonged state of alert. Blocking one part of this process reduced inflammation and improved healthy aging in mice, suggesting…...
