Abstract
In the prescriptions of an endocrinologist to patients with diabetes mellitus, glucagon-like peptide agonists, belonging to the group that affects the incretin system of the body, have recently been increasingly appearing. In addition to the pronounced hypoglycemic effect and high safety, these drugs also have many pleiotropic properties due to the presence of glucagon-like peptide receptors in the vascular endothelium, kidneys, heart and nervous tissue. The purpose of this work is to describe the most studied neuroprotective effects of this class of drugs. As materials in the course of the work, studies of domestic and foreign colleagues published in the period from 2008 to 2022 were used. Our work has shown that the neuroprotective effect of GLP-1 is associated with the activation of the corresponding receptor systems in the central nervous system, which leads to increased cellular survival in ischemic conditions by reducing reactive oxygen species, stimulating beta-oxidation by mitochondria, and reducing pro-inflammatory cytokines. In addition, the analysis of the literature also established the positive role of GLP-1 in neurodegenerative diseases – drugs reduce the amount of unnormal proteins (alphasynuclein, microtubular T-peptide, etc.), reduce the activity of non-enzymatic glycation of proteins in hyperglycemia, as well as reduce insulin resistance. The effects described above were analyzed during preclinical trials of GLP-1, and also demonstrated their validity in human models during some clinical trials. However, the data obtained is not yet sufficient to form clear indications for this class of drugs in neurology, so the topic requires further study and large clinical trials.
