ARA-290 is a synthetic 11-amino acid peptide derived from the helical region of erythropoietin (EPO), engineered to selectively activate the innate repair receptor (IRR) without triggering EPO’s erythropoietic effects. Research into ARA-290 focuses on its potent cytoprotective, neuroprotective, and anti-inflammatory properties. Studies have examined its potential in models of neuropathic pain, metabolic disease, and tissue injury, where it appears to reduce inflammatory cytokine signaling and promote cellular survival. Its selective receptor profile makes it a compelling candidate for research into chronic inflammation and nerve repair.
