Neuroprotection Peptide Research

Neuroprotection research focuses on preserving neuronal structure and function against injury, ischemia, toxic insult, chronic oxidative stress, and the early stages of neurodegenerative processes — ideally before a clinical diagnosis has been established. As a preventive and early-intervention research area, it differs from neurodegenerative disease treatment in its focus on brain resilience and preservation of healthy neurons. Peptides including Semax, Cerebrolysin, Humanin, SS-31, Selank, and related bioregulators are studied for their neuroprotective mechanisms across diverse insults. This section covers research on peptides and bioregulators with neuroprotective applications in brain injury, aging, and neurological vulnerability.

ARA-290 and Innate Repair Receptor (IRR/CD131) Signaling in Alzheimer’s Research: Monocyte Modulation and Aβ Clearance

Peptides and innate repair receptor signaling research explores a pathway linked to tissue protection, nerve survival, and inflammation control, areas central to Alzheimer's disease and other neurodegenerative conditions. ARA-290 is the most studied peptide in this space, designed to activate a receptor called the innate repair receptor (IRR) without triggering the blood-forming effects of erythropoietin, the hormone that inspired it....

Peptides and BDNF Upregulation Research – Research Guide

BDNF, or brain-derived neurotrophic factor, is a protein the brain produces to keep neurons healthy, strengthen connections between them, and support the formation of new memories. Peptides and BDNF upregulation research investigates whether certain compounds can increase BDNF levels and, in doing so, support the brain's capacity to adapt and reorganize, a process scientists call neuroplasticity. Semax is the most...
