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.

Brain &amp; Neurons

Participants: Healthy middle-aged adults 
Dosage: 1200 mg/day of NR for 4 weeks

NR (nicotinamide riboside) raises blood NAD+ (nicotinamide adenine dinucleotide) levels more than NMN (nicotinamide mononucleotide) in healthy adults.

Approved Human Study Sets Up Pivotal Test for Aging Theory from Harvard’s David Sinclair

In a major proving ground test for the longevity field, the FDA has given its approval for a human trial for a gene therapy attempting a near-total rejuvenating reset of cells.

The FDA has greenlighted Life Biosciences’ first human trial testing whether their gene therapy can confer a near-total rejuvenating reset of cells.

Clinical Trials

Model: 22-month-old male C57BL/6NIH mice 
Dosage: 400 mg/kg of NR for eight weeks, administered in food

Treating aged mice with the NAD+ (nicotinamide adenine dinucleotide) precursor NR (nicotinamide riboside) improves memory and reduces pro-inflammatory immune cells.
