1/Short thread on #Longevity
Longevity is a complex challenge, it appears that humans have a rough cap to #lifespan at about 120 years of age (even if you eat healthy, exercise and get lucky with great genes and a great environment).

3/ There's promising data around #calorierestriction and #MTOR activating molecules like #rapamycin, which in other species can extend #lifespan by 10-15% (which if we're lucky, for the few it might extend the human lifespan cap to 132-138 years of age). discovermagazine.com/mind/the-two-f…
1 approach to understanding #covid19 infection is to examine co-morbidities & ask what's common?
Most prevalent Cov19 co-morbs:
1)↗️age
2)Hypertension
3)Diabetes
4)Cardiovascular disease
5)Kidney disease
6)Chronic respiratory disease (esp COPD)
8)Cancers
9)BMI>40

These are diverse diseases & increasing age technically not a disease at all. However, there is at least 1 factor in common among all of the co-morbidities identified thus far:
INFLAMMATION

A survey of the co-morbidities revealed another commonality; a close association w/ dysregulation of the pro-inflammatory, neutrophil-recruiting cytokine, IL-17A.
IL-17A is made by multiple immune cell types, including lung-resident innate lymphoid cells (ILC3s).

Today's player: #mTORi, mammalian/mechanistic target of rapamcyin inhibitors
Rapamcyin was @US_FDA approved for #kidneytransplant in 2003.
It was isolated from a soil sample from which island in 1975?

2/ Meet mTOR, a phosphatidylinositol 3-kinase (PI3)-related kinase (adds a phos). mTOR adds a phosphoryl group to serine/threonine residues.
It is a key component of the complexes mTORC1 and mTORC 2 - which regulate processes including cell growth, proliferation, and survival.

3/ mTOR inhibition blocks "Signal 3" of #TCell activation - reducing cytokine dependent cell proliferation and activation.
