Key Findings
- AB-9 peptide increased proliferation of aged thymocytes
- AB-9 promoted differentiation of thymocytes
- AB-9 reduced apoptosis of thymocytes, while T-31 and AB-17 had no effect
Practical Outcomes
- The result hints that targeting the thymus with AB-9 could someday support immune aging, but there’s no dosage, safety, or human data yet. For now, it’s a research clue rather than a ready‑to‑use protocol for biohackers.
Summary
A lab study found that one specific peptide, called AB-9, helped old immune cells from the thymus grow and avoid dying when they were grown in a dish. The other two peptides tested didn’t show this effect. This suggests AB-9 might have anti‑aging effects on the thymus, but the work was only done in cell culture, not in people.
Abstract
The effects of T-31, AB-17, and AB-9 peptides on old (passage 8) thymocyte culture were studied. Only AB-9 peptide exhibited a complex geroprotective effect on thymocytes during their aging. Peptide AB-9 stimulated proliferative activity and differentiation of thymocytes and inhibited their apoptosis.
