What Is Mosaic Aging? How Organs Age at Different Rates

A new framework proposes that the patchwork nature of aging, where different organs deteriorate at different speeds, may hold the key to understanding the ultimate cause of death.

(University of Glasgow logo | Scotland.org)

A new framework proposes that aging occurs unevenly in cells, tissues, and organs, and that targeting the fastest-aging tissues may extend lifespan.

Model: Middle-aged cynomolgus monkeys
Dosage: 30 mg/kg/day of vitamin C, orally administered for 40 months

Vitamin C Alleviates Aging in Monkeys

Vitamin C improves brain volume and connectivity, reduces biological age, enhances metabolic health, and alleviates underlying aging drivers, such as cellular senescence, in older monkeys. 

Could Aging Leave a "Memory" That Spreads and Even Passes to the Next Generation?

A new aging model posits that aging imprints signatures across molecular, tissue, and organ system levels, and these signatures may also transmit across generations.

A new theory posits that aging imprints molecular-, cellular-, tissue-, and organ system-level signatures that may transmit across generations.

Model: Young (2- to 4-month-old) and aged (9- to 10-month-old) C57Bl/6JR mice, APP/PS1 mice, and 5xFAD mice 
Dosage: 0.2 mg/mL of doxycycline in drinking water starting at least 7 days before surgery and ceased 2 days before the partial cellular reprogramming window for engram tagging, after which it was immediately reintroduced

Gene Therapy Restores Cognitive Function in Aging and Alzheimer’s Disease

Delivering a gene therapy targeting ensembles of neurons that store memories restores learning and memory capabilities in mouse models of aging and Alzheimer’s disease.

(The study’s principal investigator, Professor Johannes Gräff | 24 Heures)

A partial cellular reprogramming gene therapy targeting memory trace cells restores facets of learning and memory in aged mice and those modeling Alzheimer’s disease.
