Model: 16-month-old male C57BL/6 mice 
Dosage (oral): 5 mg/kg of dasatinib and 50 mg/kg of quercetin biweekly for 4 months

Senolytic Treatment Rejuvenates Intestines 

The senolytic — compound that eliminates aged cells — combo dasatinib and quercetin (D+Q) promotes small intestine regeneration in aged mice.

Model: Aged (20-month-old) male C57BL/6J mice fed a high-fat diet to induce obesity
Dosage (oral): 30 mg/kg of GABA

Supplementing with GABA (γ-aminobutyric acid) — the brain’s inhibitory neurotransmitter — prevents muscle and strength loss, fat gain, and insulin resistance in aged mice fed excess calories.
