In conclusion, we have developed an effective PILs strategy to deliver the AUF1 plasmid to a specific target, and this system may be useful for the development of new anti-aging drugs.
Considering the Evidence for Vascular Amyloidosis as a Cause of Aging
https://www.fightaging.org/archives/2017/11/considering-the-evidence-for-vascular-amyloidosis-as-a-cause-of-aging/
The balance of evidence for the aging of the cardiovascular system suggests the following view. It starts off in the blood vessels, with the accumulation of senescent cells and cross-links. Cross-links directly stiffen these tissues, while senescent cells produce inflammation and changes in cell behavior that promote calcification - again leading to stiffness. These and other processes also disrupt the delicate balance of cell signaling responsible for blood vessel constriction and relaxation. All of this combines to degrade the feedback system controlling pressure in the cardiovascular system, and blood pressure rises as a result. In turn, the heart remodels itself, becoming larger and weaker.
At the same time as this is going on, increased oxidation in the lipids carried by the bloodstream is produced as a result of greater inflammation, or via processes such as cells becoming taken over by damaged mitochondria. Blood vessel walls become irritated by oxidized lipids, and that produces a feedback loop in which inflammatory signaling draws in cells that attempt to clean up the problem ...
