Livagen – A Potential Bioregulator Peptide

by | Jul 13, 2022 | Research

Livagen is classified by scientists as a potential peptide bioregulator of the liver, GI tract, and immune system. Livagen peptide has been suggested to act on the DNA and gene expression patterns. The gene-activating potential of Livagen on the immune system and GI tract may stem from certain cell aging prevention characteristics of the peptide.

Livagen peptide has been suggested to potentially modulate Chromatin, and thereby impact immune system function. Due to DNA packing, DNA in eukaryotes may reduce to roughly 100,000. DNA is a double helix protein wrapped by histone proteins, which may combine to form chromatin structures. The chromatin structure may subsequently condense to form chromosomes.[2] Researchers suggest that “Livagen causes de-heterochromatinization (activation) of chromatin, which is realized via modification of heterochromatin and heterochromatinized regions.”

Livagen peptide may potentially stimulate chromatin decondensation by activating multiple genes in lymphocytes, according to research. This mechanism may promote the activation of silent genes, such as ribosomal genes, which may potentially boost protein synthesis and cell activity.[3] During the investigation, a comparison of LivagenEpithalon, and Vilon was made. Livagen peptide was suggested to exhibit four impacts on lymphocytes, according to the results. Unpacking chromatin was one among them, as well as decondensation, reactivation of ribosomal genes to activate synthetic processes, and the changing the expression of genes may then occur.

B cells, T cells, and natural killer cells are all types of lymphocytes. T cells appear to produce antibodies specific to cells infected with viruses, bacteria, or malignant cells, whereas B cells appear to produce antiviral and antibacterial antibodies. T cells may produce cytokines that influence immune responses and inflammation.

Livagen peptide may potentially influence pain perception. Enkephalins are peptides that are suggested control nociception. They attach to mu and delta-opioid receptors and may potentially transmit pain signals. When Mu receptors, which bind to morphine, are triggered, they may lower pain, blood pressure, and awareness. Delta receptors may alleviate pain and may be involved in opiate-induced respiratory depression.[4]According to Livagen research, the peptide may block enkephalin-degrading enzyme activity in the blood, causing a rise in natural painkiller levels.

Livagen peptide may interact with the heart muscle. According to research, chromatin dysregulation may be one of the pathogenic components of  hypertrophic cardiomyopathy (HCM) and atherosclerosis.[5] The scientists suggest that “The peptide bioregulator Livagen could induce reactivation (deheterochromatinization) of chromatin to modify heterochromatinized chromosomal regions in cultured lymphocytes.” Scientists believe that genes produced by chromatin decondensation in lymphocytes might minimize the long-term consequences of several forms of heart disease. Livagen peptide may potentially perform this function. In research models of hypertrophic cardiomyopathy (HCM), altered lymphocyte gene expression might minimize scarring and inflammation.[6]

Livagen may impact the gastrointestinal tract. According to the Livagen peptide study, the peptide might increase GI tract vagal nerve signaling and change levels of prostaglandins and mucosal nitric oxide. This may lead to gastroprotection, possibly managing diarrhea, symptoms, and inflammatory bowel disease.[7]
