Model: 11-month-old male C57BL/6J mice 
Dosage: 30 mg/kg/day of NTX-748 (based on a small molecule called 78c) for 4 months, administered orally

Buck Institute scientists find that blocking the CD38 enzyme, which elevates NAD+ (nicotinamide adenine dinucleotide), counteracts age-related cognitive and physical decline in mice.

Brain &amp; Neurons

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.

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.

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.

Elevating the naturally occurring molecule NAD+ (nicotinamide adenine dinucleotide) improves memory and corrects gene-splicing patterns in a worm and a mouse model for dementia.

Participants: Healthy male adults between the ages of 18 and 50 
Dosage: 714 mg/day of nicotinamide and 19 mg/day of pyridoxine for nine days

In a randomized human trial, combining nicotinamide with vitamin B6 increases stem cell activation and muscle-growth capacity in response to exercise.
