Key Findings
- Both AB-O and R-1 raise CD5 expression in cultured thymic cells
- AB-O encourages differentiation toward CD4+ helper T‑cells, but less strongly than R-1
- R-1 promotes maturation of both CD4+ helper and CD8+ cytotoxic T‑cells, suggesting immunomodulatory and antiallergic activity
Practical Outcomes
- At this stage the findings are limited to cell‑culture experiments, so there’s no dosage or safety data for humans. Biohackers should treat these peptides as experimental leads rather than ready‑to‑use supplements. Keep an eye on future animal or clinical studies before considering any self‑administration.
Summary
The study looked at two small protein fragments, called AB-O and R-1, and found they can boost certain immune‑cell markers in lab‑grown human and rat thymus cells. Both increased a protein called CD5, which is linked to T‑cell development. R‑1 was better than AB-O at pushing immature cells to become mature helper (CD4) and killer (CD8) T‑cells, hinting it might act as an immune‑boosting and anti‑allergy agent.
Abstract
We studied molecular mechanisms of immunoprotective effects of two dipeptides, AB-O and R-1, on cultured human and rat thymic cells. Both dipeptides were shown to increase the expression of lymphocyte differentiation marker CD5 in thymic cells. Dipeptide AB-O induced T-cells precursor differentiation towards CD4(+)T-helpers and its effect was weaker than that of dipeptide R-1. Dipeptide R-1 stimulates differentiation of CD5(+) cells to mature T-helpers and cytotoxic CD8(+) T cells and hence can be considered as a bioactive substance possessing immunomodulator and antiallergic activity.
