Semax + Selank

Semax and Selank are synthetic peptides studied for their complementary effects on brain function, combining Semax’s neuroprotective and cognitive-enhancing properties with Selank’s anxiolytic and mood-stabilizing effects. Together, they are explored for supporting focus, memory, stress reduction, and overall cognitive performance without significant sedation.

Gene Expression Modulation in Stress and Immunity

Selank alters the expression of over 30 genes related to inflammation—such as cytokines, chemokines, their receptors, and immune development regulators like Bcl6—under social stress conditions in mice.

Immune Modulation of Pro-inflammatory Cytokines During Stress

In a social stress model, Selank significantly reduced stress-induced elevations in IL‑1β, IL‑6, TNF‑α, and TGF‑β1, while helping restore levels of anti-inflammatory IL‑4.

Selank

Regulates Neurotransmiters and Enhances BDNF Expression

Selank modulates the balance of monoamines such as GABA, serotonin, and dopamine, and has been shown to increase BDNF expression in the rat hippocampus—supporting mood and neuroplasticity.
