Immunomodulatory Peptide

What Is Selank Peptide?

Selank is a synthetic peptide that has its roots in the fascinating field of immunomodulation and neuropharmacology. This bioactive compound is derived from tuftsin, an immunomodulatory peptide. 

An explanation of Selank would be complete without an explanation on Tuftsin. 

Tuftsin, in its natural form, is recognized for its remarkable influence on the immune system and its ability to regulate the body’s immune responses.

Tuftsin itself is composed of four amino acids: threonine, lysine, proline, and alanine. This peptide was originally isolated from blood serum and has since been the subject of extensive research due to its immunomodulatory properties.

Researchers discovered that tuftsin played a pivotal role in regulating immune functions, promoting the phagocytic activity of macrophages, and influencing various aspects of the immune response.

Selank, however, represents a refined and synthetic variation of tuftsin. It was meticulously designed to capitalize on the therapeutic potential of its parent peptide while addressing concerns about stability and potential side effects. Selank is a smaller and more stable peptide, composed of just seven amino acids, making it an ideal candidate for therapeutic applications.

One of the primary goals in creating Selank was to harness the immunomodulatory and neuropharmacological properties of tuftsin while reducing any potential adverse effects that might arise from using the full-length peptide. By optimizing the molecular structure and properties of Selank, researchers aimed to create a potent yet safer compound for a wide range of applications in neuroscience and psychopharmacology.

The synthesis of Selank has opened up new avenues for research and potential therapeutic use, making it a subject of great interest in the scientific and medical communities. Its smaller size and stability allow for easier administration and better bioavailability, making it a compelling candidate for further exploration and clinical application.

How Does Selank Work?

Selank’s mechanisms of action are multifaceted, with several notable effects on the central nervous system. Two key mechanisms of action that contribute to its therapeutic potential are:

Increases BDNF Production:

Brain-Derived Neurotrophic Factor (BDNF) is a crucial protein that promotes the growth, differentiation, and survival of neurons.

BDNF plays a pivotal role in neuroplasticity, learning, memory, and overall cognitive function. Selank has been shown to increase the production of BDNF in the brain, potentially enhancing synaptic plasticity and neuroprotection. This effect could have far-reaching implications for cognitive enhancement and the treatment of various neurological and neuropsychiatric conditions.

Research and studies have provided evidence of SELANK’s role in enhancing BDNF levels. For example, a study published titled Intranasal Administration of the Peptide Selank Regulates BDNF Expression in the Rat Hippocampus in vivo demonstrated that SELANK “Selank significantly increased the concentration of BDNF mRNA in the hippocampus” and 

“The influence of Selank intranasal administration on the BDNF gene protein product level was estimated at the next stage of the study. A statistically significant 30% increase relative to the control value was found in the rat hippocampus BDNF level 24 h after the peptide administration at a dose of 250 or 500 μg/kg body weight”

showing administration significantly increased BDNF expression in the rat hippocampus, suggesting a potential role in improving cognitive function and neuroprotection.

Lowers Production of Pro-Inflammatory Compounds in the Brain:

Chronic inflammation in the brain is implicated in various neurodegenerative diseases, including Alzheimer’s disease and multiple sclerosis.

Selank has demonstrated the ability to modulate the immune response in the brain by reducing the production of pro-inflammatory compounds, such as interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α).

This anti-inflammatory property can help mitigate the neuroinflammatory processes that contribute to the pathogenesis of these conditions.

What Are The Benefits of Selank Peptide?

Selank’s multifaceted mechanisms of action underpin its potential applications in various fields, including neurology, psychiatry, and cognitive enhancement. Some potential benefits and applications of SELANK include:

Cognitive Enhancement

  • By increasing BDNF production and enhancing neuroplasticity, Selank holds promise for improving cognitive function, memory, and learning.

Anxiety and Stress Reduction:

  • Selank has anxiolytic and stress-reducing properties, which make it a potential candidate for the treatment of anxiety disorders and post-traumatic stress disorder (PTSD). It may help regulate stress hormones and improve emotional well-being.

Neurodegenerative Disorders:

  • The ability to reduce neuroinflammation and promote neuroprotection suggests that Selank may have applications in the treatment of neurodegenerative diseases, such as Alzheimer’s and Parkinson’s disease.

Immune System Modulation:

  • Selank’s immunomodulatory properties may find applications in conditions involving immune dysregulation, such as autoimmune diseases and chronic inflammatory disorders.

Selank is a promising peptide with multifaceted mechanisms of action. Its ability to increase BDNF production and reduce pro-inflammatory compounds in the brain has garnered significant interest in the scientific community. The evidence from various studies suggests that Selank has the potential to play a pivotal role in cognitive enhancement, anxiety reduction, and the treatment of neurodegenerative disorders and inflammatory conditions. 

Further research and clinical trials are needed to fully explore the therapeutic potential of Selank and its safety profile, but the existing scientific literature presents a compelling case for its potential benefits in various applications within the realm of neuroscience and psychopharmacology.

Does Selank help reduce anxiety?


Selank has garnered interest for its potential anxiolytic effects, and these effects can be explained as follows:

Neurotransmitter Modulation: Selank is believed to influence the levels of various neurotransmitters, such as serotonin and dopamine, which play crucial roles in regulating mood and emotions. By modulating these neurotransmitters, Selank may help regulate anxiety and stress responses. We’ll go more into detail on Selank’s role with dopamine and serotonin below. For now, these are other ways Selank helps to reduce anxiety. 

Stress Resilience: Selank administration can enhance stress resilience. This suggests that SELANK may mitigate the physiological and psychological responses to stress, making it a potential candidate for anxiety reduction.

Selank may influence the hypothalamic-pituitary-adrenal (HPA) axis, a central component of the body’s stress response system. By regulating the HPA axis, Selank may help modulate the secretion of stress hormones, such as cortisol. This regulation can mitigate the physiological stress response, reducing the impact of stress on the body.

Under the topic of stress resilience, let’s have a look at neurotransmitter Balance: 

Selank is thought to affect the balance of neurotransmitters, particularly those involved in stress and anxiety regulation. By modulating these neurotransmitters, it can help restore balance and reduce excessive stress responses.

Selank’s neuroprotective properties contribute to stress resilience by shielding neurons from the harmful effects of chronic stress. This protection may involve preventing neuronal damage, enhancing neuroplasticity, and promoting adaptive responses to stress.

In essence, Selank appears to enhance the body’s ability to cope with stressors, potentially mitigating the physiological and psychological responses to stress. This capacity to improve stress resilience makes SELANK a candidate for managing anxiety, as anxiety often arises in response to stress and stress-related triggers.

Other ways Selank helps to reduce anxiety is due to its anxiolytic properties. Anxiolytic effects are often demonstrated through animal studies, where SELANK has been shown to reduce behaviors associated with anxiety in response to stressors. These behaviors may include increased vigilance, reduced exploratory behavior, and other stress-induced responses.

SELANK’s anxiolytic properties are attributed to its ability to modulate neurotransmitters, reduce anxiety-like behaviors, and promote a more tranquil emotional state. These characteristics make it a potential tool for managing anxiety, particularly in situations where stress is a contributing factor.

Does Selank boost learning speed and memory? ((both long and short-term).


Not only does Selank boost learning speed and memory, but it also does this for short and long-term memory!

Isn’t that great?

Selank’s potential to boost learning speed and memory can be explained through its impact on neuroplasticity and neurotrophic factors:

BDNF Enhancement: Selank has been shown to increase the production of brain-derived neurotrophic factor (BDNF), a protein crucial for neuronal growth, synaptic plasticity, and memory formation. Higher BDNF levels are associated with improved cognitive function and enhanced learning and memory.

Synaptic Plasticity: By increasing BDNF and promoting synaptic plasticity, Selank may facilitate the formation and consolidation of memories. This can lead to both short-term and long-term memory improvements.

Cognitive Performance: Some studies suggest that Selank administration can lead to improved cognitive performance, including faster learning and better memory retention. This cognitive enhancement can have both short-term and long-term benefits.

How does Selank Regulate dopamine and serotonin expression?

Selank’s regulation of dopamine and serotonin expression is a complex process that involves interactions with the neural and hormonal systems. While the exact mechanisms are not fully understood, research suggests that Selank may influence the levels of these neurotransmitters through several potential pathways

Let’s start with dopamine regulation which can be split into 3 sections; dopamine synthesis, dopamine receptor sensitivity and dopamine reuptake inhibition. 

  • Dopamine Synthesis: Selank may enhance the synthesis of dopamine, a key neurotransmitter associated with motivation, reward, and mood regulation. It can promote the conversion of precursor molecules into dopamine, leading to an increase in its availability in the brain.
  • Dopamine Receptor Sensitivity: Selank may modulate the sensitivity of dopamine receptors in the brain. By making these receptors more responsive to dopamine, it can amplify the effects of this neurotransmitter, potentially leading to improved mood and motivation.
  • Dopamine Reuptake Inhibition: Selank may inhibit the reuptake of dopamine, meaning it can prevent dopamine from being taken back up into the neurons after it’s released. This results in a longer duration of action for dopamine in the synaptic cleft, potentially leading to enhanced mood and motivation.

Now, when it comes to serotonin, often referred to as the “feel-good” neurotransmitter, Selank may have the capacity to modulate serotonin levels in the brain. Understanding how Selank interacts with the serotonin system provides valuable insights into its potential as an anxiolytic agent and its role in promoting emotional calm and well-being: 

  • Serotonin Synthesis: Selank may also play a role in the synthesis of serotonin. It may facilitate the conversion of precursor molecules into serotonin, thereby increasing its levels in the brain.
  • Serotonin Receptor Sensitivity: Selank can potentially modulate the sensitivity of serotonin receptors, making them more responsive to serotonin. This enhanced receptor sensitivity may contribute to the anxiolytic (anxiety-reducing) effects of Selank.
  • Serotonin Reuptake Inhibition: Similar to its effect on dopamine, Selank may inhibit the reuptake of serotonin. This inhibition allows for a longer duration of serotonin action in the synapse, which can have a calming and mood-stabilizing effect.

It’s important to note that Selank’s mechanisms of action on dopamine and serotonin are still being researched, and the precise details may vary depending on individual factors. 

Furthermore, the extent to which Selank influences these neurotransmitters and the specific brain regions it targets may vary. The regulation of these neurotransmitters is likely part of Selank’s broader effects on mood, stress response, and overall emotional well-being.
