Product Info
Selank is a synthetic peptide analogue of the naturally occurring immunomodulatory peptide tuftsin, commonly used in laboratory research to study neuropeptide regulation, stress response, and cognitive function. It is of interest in controlled experimental settings examining neurotransmission, anxiety-related pathways, and peptide–receptor interactions. Selank is supplied strictly for research purposes only and is not intended for human or veterinary use.

Overview
Selank is a synthetic hexapeptide (Thr-Lys-Pro-Arg-Pro-Gly) derived from thymosin alpha-1 sequence, designed as an anxiolytic and immunomodulatory agent. The peptide is a tuftsin analog that targets immune cells and central nervous system tissues to modulate stress response and immune function. Selank is extensively studied for its potential in reducing anxiety, supporting stress resilience, and enhancing immune competence. Research indicates the peptide promotes anti-anxiety effects through central monoamine modulation while simultaneously enhancing immune cell function and cytokine production. Selank represents a valuable research tool for investigating anxiety disorders, stress adaptation, neuroimmunology, and therapeutic approaches to anxiety and immune dysfunction.

Biochemical Characteristics
Selank is a 6-amino acid peptide with molecular weight of approximately 753 Da. The peptide sequence contains both hydrophobic and charged amino acids enabling multiple receptor interactions in central and peripheral nervous systems. The peptide is water-soluble and crosses the blood-brain barrier efficiently, localizing to central nervous system tissues involved in mood and stress regulation. Selank demonstrates stability across physiological pH ranges (6.5–8.0) and resists enzymatic degradation, supporting extended biological half-life. Cellular uptake occurs through receptor-mediated mechanisms and peptide transporter pathways. The peptide localizes to hippocampus, amygdala, prefrontal cortex, and immune tissues where anxiolytic and immunomodulatory effects are exerted.

Pathway / Mechanistic Context
Monoamine Enhancement Selank increases dopamine and serotonin availability in prefrontal cortex and limbic regions through modulation of monoamine transporter function and synthesis, producing anxiolytic and mood-enhancing effects. GABAergic Modulation The peptide enhances GABAergic inhibitory tone in amygdala and other anxiety-regulating circuits, reducing excitatory drive and promoting anxiolysis. HPA Axis Modulation Selank reduces hypothalamic-pituitary-adrenal (HPA) axis hyperresponsiveness and excessive glucocorticoid signaling, promoting adaptive rather than maladaptive stress responses. Immune Cell Activation The peptide activates macrophages, neutrophils, and T cells through tuftsin receptor binding, enhancing phagocytosis, cytokine production, and immune cell proliferation. Cytokine Enhancement Selank promotes production of IL-2, IL-6, TNF-α and other pro-inflammatory cytokines necessary for effective immune responses and immune cell communication. Stress-Induced Immunosuppression Reversal The peptide counteracts stress-induced suppression of immune function, restoring normal immune cell proliferation and cytokine production capacity.
