Selank Overview

Selank is a synthetic peptide that was developed in Russia as a potential treatment for anxiety and cognitive disorders. It is derived from the naturally occurring peptide tuftsin, which modulates the immune response.

Selank is primarily used for its anxiolytic (anti-anxiety) properties. It has been found to reduce anxiety and promote a sense of calmness and relaxation. It works by regulating the release of stress hormones in the body, such as cortisol, and modulating the activity of neurotransmitters like serotonin and dopamine.

In addition to its anxiolytic effects, Selank has also shown potential as a cognitive enhancer. It may improve memory, focus, and mental clarity, making it useful for individuals looking to optimize their cognitive performance. Research suggests that Selank increases dopamine and serotonin levels in the brain, which are involved in various cognitive processes.

Selank has also been studied for its immunomodulatory properties. It can help regulate and balance the immune system response; potentially benefiting conditions associated with immune dysfunction. However, more research is needed to fully understand its efficacy.

Selank Anxiety Effects Based on Genes Related to GABA Neurotransmitter

According to a study published in the National Center for Biotechnology Information (NCBI), the administration of Selank has been found to affect the mRNA levels of genes involved in neurotransmission, specifically those related to the GABA neurotransmitter, in the frontal cortex of rats. This suggests that Selank may have an impact on the GABAergic system, which is involved in anxiety regulation.

Another study published on NCBI states that Selank has an anxiolytic effect comparable to classical benzodiazepine drugs, which enhance the function of the GABA neurotransmitter. This further supports the notion that Selank affects the GABAergic system and can help reduce anxiety.

Additionally, research indicates that Selank might influence the expression of certain genes involved in GABAergic neurotransmission. This effect on gene expression may contribute to Selank’s anxiolytic properties.

Selank and the Immune System in Anxiety

Selank, a synthetic peptide, has been studied for its potential effects on the immune system in anxiety. The connection between Selank and the immune system lies in its immunomodulatory properties. Research suggests that Selank can serve as a novel immunomodulator in patients that suffer from anxiety-asthenic disorders by regulating cytokine levels. Cytokines are small proteins involved in cell signaling and immune responses.

Inflammatory processes and immune responses play a role in anxiety disorders, and Selank has shown potential in modulating these factors. Studies indicate that Selank can influence cytokine levels under conditions of social stress, suggesting its impact on the immune system. This implies that Selank may help regulate immune responses associated with anxiety.

Furthermore, Selank has been associated with antiviral immune-stimulatory effects, potentially strengthening and stimulating immune function. By enhancing immune function, Selank may contribute to an overall improvement in anxiety symptoms.

While the exact mechanisms through which Selank affects the immune system in anxiety are still being investigated, these studies suggest a connection between Selank, immune modulation, and anxiety.

Selank Research with Memory and Learning

Selank is a synthetic peptide studied for its effects on memory and learning processes. Several research studies have investigated the impact of Selank on cognitive function and have found positive results.

One study published in the journal “Bulletin of Experimental Biology and Medicine” showed that Selank protected against ethanol-induced memory impairment by regulating the content of brain-derived neurotrophic factor (BDNF) in the hippocampus and prefrontal cortex. BDNF is a protein that plays a crucial role in promoting the survival and growth of neurons, as well as in synaptic plasticity, which is essential for learning and memory formation.

Another study conducted on rats examined the actions of Selank on learning and memory processes using an active avoidance conditioned reflex. The researchers found that Selank had optimized actions on memory and improved the learning process.

Furthermore, research published in the journal “Neuroscience and Behavioral Physiology” demonstrated that Selank facilitated learning in animals exposed to hypoxia, a condition of low oxygen levels. The study suggested that Selank could correct cognitive impairments resulting from antenatal hypoxia.

Additionally, a study conducted on rats in unpredictable chronic mild stress conditions found that Selank enhanced the effect of diazepam, a benzodiazepine drug, in reducing anxiety. This suggests that Selank may have potential anxiolytic properties that positively impact cognitive function.

Selank Research and Pain

Selank seems to play a role in preventing the breakdown of natural enkephalins, which are peptides that bind to opioid receptors and help reduce the severity of pain. Enkephalins are also involved in the body’s stress response and are found abundantly in the brain and adrenal glands. By preserving the levels of enkephalins in the brain, Selank may help reduce the impact of stress on memory, learning, and concentration.

Importantly, Selank has been found to have minimal side effects and is well-absorbed when administered subcutaneously in mice. However, it’s important to note that the dosage used in mice does not directly translate to humans. The Selank available for purchase at our shop is intended solely for educational and scientific research purposes, and it is not meant for human consumption.
