Key Findings
- Radiation‑induced premature aging caused stronger damage to pancreatic cells, blood vessels, and regeneration capacity compared to normal aging.
- The tri‑peptide T‑38 (Lys‑Glu‑Asp) administered to these aged rats activated repair processes in the pancreas.
- Treatment with T‑38 restored more normal endocrine (hormone) function in the pancreas of the irradiated, aged animals.
Practical Outcomes
- For biohackers, the study hints that a short peptide might support pancreatic health and metabolic regulation during aging, but it’s only been shown in rats and at unknown doses. Until human trials are done, there’s no concrete protocol to follow, though the concept could inspire further research into peptide‑based pancreas support.
Summary
In rats that age faster because of radiation, a tiny three‑amino‑acid peptide (Lys‑Glu‑Asp, called T‑38) helped the pancreas repair itself and improve hormone balance. The same kind of age‑related damage was worse in these fast‑aging rats than in normal old rats, but the peptide boosted the organ's natural healing.
Abstract
This study was devoted to the evaluation of morphofunctional alterations in the pancreas in the conditions of physiological and premature aging using the experimental model of irradiation-induced aging, and the possibility of peptidergic regulation of age-related alterations in the pancreas was also studied. Age-related alterations in the pancreas of old animals in the conditions of physiological aging were revealed in the form of dystrophic alterations of main cell populations, disordered microcirculatory vascular channels and reduced level of physiological regeneration of this organ. In the conditions of irradiation-induced premature aging the above mentioned manifestations of dystrophic alterations in the pancreas tissue were found to be more pronounced. Administration of tripeptide T-38 (Lys-Glu-Asp) to old irradiated animals activated the processes of post-irradiation reparative regeneration, thus restoring the disordered endocrine homeostasis in the pancreas.
