The gene-expression alteration caused by the action of the peptide Semax was compared with the gene expression of the "ischemia" group animals at 3 and 24 h after permanent middle cerebral artery occlusion (pMCAO). The peptide predominantly enhanced the expression of genes related to the immune system. Three hours after pMCAO, Semax influenced the expression of some genes that affect the activity of immune cells, and, 24 h after pMCAO, the action of Semax on the immune response increased considerably. The genes implicated in this response represented over 50% of the total number of genes that exhibited Semax-induced altered expression. Among the immune-response genes, the expression of which was modulated by Semax, genes that encode immunoglobulins and chemokines formed the most notable groups. In response to Semax administration, 24 genes related to the vascular system exhibited altered expression 3 h after pMCAO, whereas 12 genes were changed 24 h after pMCAO. These genes are associated with such processes as the development and migration of endothelial tissue, the migration of smooth muscle cells, hematopoiesis, and vasculogenesis.
Semax affects several biological processes involved in the function of various systems. The immune response is the process most markedly affected by the drug. Semax altered the expression of genes that modulate the amount and mobility of immune cells and enhanced the expression of genes that encode chemokines and immunoglobulins. In conditions of rat brain focal ischemia, Semax influenced the expression of genes that promote the formation and functioning of the vascular system.The immunomodulating effect of the peptide discovered in our research and its impact on the vascular system during ischemia are likely to be the key mechanisms underlying the neuroprotective effects of the peptide.
Peptides are composed of amino acids linked together by Peptides. The smallest Peptides can consist of three amino acids, such as thyrotropin-releasing hormone (TRH). Most Peptides can be made up of dozens or even hundreds of amino acids. The primary secretion organs for Peptides are the hypothalamus and the pituitary gland; however, Peptides have also been found in other organs, such as the gastrointestinal tract, brain tissue, lungs, and heart. Peptides are a type of endogenous substance that consists of protein chains containing polypeptide compounds. Examples of Peptides include thyrotropin-releasing hormone, Peptides and its analogs, Peptides and its analogs, adrenocorticotropic hormone, gonadotropins, Peptides and its analogs, Peptides-like Peptides, calcitonin, and parathyroid hormone.
