This study aimed to investigate the association between frailty index and circulating CAP2 concentration in 467 community-dwelling older adults (median age: 79; range: 65-92 years). The selected robust regression model showed that circulating CAP2 concentration was not associated with chronological age, as well as sex and education. However, circulating CAP2 concentration was significantly and inversely associated with the frailty index: a 0.1-unit increase in frailty index leads to ~0.5-point mean decrease in CAP2 concentration. Furthermore, mean CAP2 concentration was significantly lower in frail participants (i.e., frailty index ≥0.25) than in non-frail participants.
This study shows the association between serum CAP2 concentration and frailty status for the first time, highl...

Does Amyloid-β Aggregation Cause Broad Disruption of Proteostasis?
https://www.fightaging.org/archives/2023/08/does-amyloid-%ce%b2-aggregation-cause-broad-disruption-of-proteostasis/
Researchers here speculate on the ability of insoluble amyloid-β aggregates to be broadly disruptive of the solubility of many other proteins, and thus disruptive to cell and tissue function. Is this important in aging? The evidence here shows the existence of the mechanism in a lower species, but that doesn't necessarily show that it has a sizable effect in mammals. Still, it is an interesting concept, potentially linking everything we know about why amyloid-β increases with a...
