What is Selank? Research Peptide Guide UK. Selank is a synthetic peptide that has attracted growing interest in neuroscience and immunology research. It's a stabilised analogue of Tuftsin — a naturally occurring peptide involved in immune regulation — and was originally developed by the Institute of Molecular Genetics in Russia. What makes Selank particularly interesting to researchers is its multi-target profile, spanning anxiety-related behaviour, cognitive function, and immune modulation.
What is Selank Made From?
Selank (Thr-Lys-Pro-Arg-Pro-Gly-Pro) is a seven-amino-acid analogue of Tuftsin with a C-terminal extension that gives it a significantly extended half-life compared to its parent peptide. This improved stability makes it more practical to work with in laboratory settings. It retains the Tuftsin-derived sequence that interacts with immune receptor pathways, while also demonstrating activity across neurological systems.
What is Selank Studied For?
Research into Selank has explored several areas across neuroscience and immunology. Here's a plain-language overview of the key areas researchers have investigated:
Anxiety and Stress Response
Selank has been studied in preclinical models of anxiety and stress, with research exploring its interactions with the GABAergic system and serotonin pathways — two of the brain's key regulatory systems for mood and stress response.
BDNF and Neurotrophin Signalling
Like Semax, Selank has been shown in preclinical studies to influence BDNF (brain-derived neurotrophic factor) expression — a protein involved in neuronal survival and synaptic plasticity. This makes it of interest in neuroplasticity and cognitive research.
Cognitive Function and Memory
Animal model studies have explored Selank's effects on learning and memory consolidation, with researchers attributing some of these effects to its influence on enkephalin degradation and monoaminergic systems.
Immune Modulation
Via its Tuftsin-derived sequence, Selank has been studied for its effects on immune system regulation, including modulation of interleukin expression — positioning it as a compound of interest in both neurological and immunological research contexts.
