Cyclo(Gly-L-Pro), a cyclic dipeptide, demonstrates significant immunomodulatory activity by stimulating beneficial immune responses while simultaneously suppressing the release of the pro-inflammatory cytokine TNF-α, reducing mRNA expression of IL-1β and IL-6, and inhibiting nitric oxide (NO) production. it has also been shown to enhance memory and improve functional recovery in animal models, indicating substantial potential for neuroscience research due to its neuroprotective and immunostimulatory properties.
