Extracellular vesicles in aging: an emerging hallmark?

Researchers reviewed studies on extracellular vesicles, tiny packages released by cells that carry proteins and genetic material. They examined whether these particles change with age and affect nearby or distant tissues. The evidence came from human studies, animal experiments, and laboratory cell studies, rather than one new group of participants. Some findings suggest that age-related changes in these particles may contribute to inflammation, weaker tissue repair, and other aging changes.

What this means for you: This is an interesting research lead, not proof that extracellular vesicles can be changed safely to slow aging. You can ignore products claiming to target them until well-tested human trials show real benefits.
