In conclusion, the present study demonstrated that TIGIT is a prominent negative immune regulator involved in immunosenescence. This novel finding is highly significant, as targeting TIGIT might be an effective strategy to improve the immune response and decrease age-related comorbidities.
Delivery of Extracellular Vesicles as a Potential Basis for Therapies
https://www.fightaging.org/archives/2018/01/delivery-of-extracellular-vesicles-as-a-potential-basis-for-therapies/
Here I'll point out a readable open access review paper on the potential use of extracellular vesicles as a basis for therapy: harvested from, say, some form of stem cell, and then delivered to a patient. One of the ways in which stem cell therapies might branch and evolve in the near future is to discard the cells themselves in favor of the signals produced by those cells. The evidence to date strongly suggests that many of the current forms of cell therapy produce their beneficial effects, such as a reduction in inflammation, via signaling. The cells themselves do not survive for long enough in large enough numbers to be making a difference through other activities.
This is not to say that all cell therapies should be replaced by signals - in most of the cases relevant to human rejuvenation, it is vital to deliver cells that stick around, integrate with tissues, and perform all of the necessary tasks required of them. To augment a failing organ such as the heart that is not natura...
