Abstract
This article describes the results of an experiment on potentiation of the hepatoprotective agent "Hepaton" with a drugantagonist of CGPR receptors.Calcitonin Gene Linked Peptide (CGRP) is a highly efficient vasoactive peptide released from sensory nerves, the main, most active form of which (α-form) is produced by alternative splicing. The CGRP receptor is a complex of a calcitonin-like receptor (CLR) and one transmembrane protein, RAMP1.At the moment, one of the most urgent topics is the study of the role of this peptide in various pathogenetic processes in humans and animals. Due to the fact that the liver is one of the largest reservoirs for CGRP receptors, the role of this peptide in the regulation of liver pathologies is obvious. Thus, it has been reliably established that in hepatopathies of various origins, the concentration of CGRP in the blood plasma increases significantly, which determines the hyperkinetics of the portal circulation characteristic of liver lesions.To assess the prospects of potentiation of hepatobiliary protector drugs using CGPR receptor antagonists, we used a drug with hepatoprotective activity "Hepaton" (developed by FGBOU VO "SPbGUVM", therapeutic dosage for rats - 0.5 mg / kg, duration of pharmacological correction - 7 days) in combination with monoclonal antibodies of class G2 (IgG2), binding with high affinity to the receptor of calcitonin-gene-related peptide (erenumab, Irinex, dosage for rats - 0.75 ml / kg, was used once before the start of the experiment) and their effect on the regeneration of hepatic pathology induced by the use of 1,2-dichloroethane (within 7 days) in standard dosages.Based on both experimental and scientific literature data, it can be concluded that drugs antagonists of CGPR receptors have an extremely wide range of applications in the future, including for potentiating other drugs used for pharmacological correction of various pathologies.Rational influence on CGPR receptors can reliably influence the maintenance of homeostasis and nociception of the hepatobiliary system.
