These pro-longevity effects are mediated by reduced T_b, reinforcing evidence that T_b is a key mediator of aging processes.

The P681R mutation in the spike protein renders the Delta variant more pathogenic than prototypic SARS-CoV-2 in infected hamsters, and facilitates spike protein cleavage and enhances viral fusogenicity.
