Immunosuppressant Peptide Abu-TGIRIS-Abu-NH2 and its Application for Treatment of Multiple Sclerosis.
Journal of Bionanoscience, 2018Co-Authors: Valery I. Turobov, Viatcheslav N. Azev, Alexei B. Shevelev, Natalia V. Pozdniakova, Yulia K. Biryukova, Arkady N. Murashev, Valery M. Lipkin, Igor P. UdovichenkoAbstract:: Immunosuppressant peptide immunocortin for the first time was described in 1993. It corresponds to residues 11-20 of human Ig heavy chain (conserved motif of VH domain). There are no data about production of immunocortin by proteolysis of Ig in vivo. Synthetic immunocortin in concentration ~ 10-9 M suppresses phagocytosis in peritoneal macrophages, ConA-dependent blast transformation of rat lymphocytes, exhibits ACTH-like neurotropic activity and was suggested as a potential drug for treatment of a multiple sclerosis (MS). Here, we report a sequence and method of synthesis of Abu-TGIRIS-Abu-NH2 (Abu, Alpha-Aminobutyric Acid), an artificial analogue of immunocortin. Biological trials of peritoneally injected Abu-TGIRIS-Abu-NH2 gave an evidence of its better efficacy versus immunocortin in a test for suppression of the experimental autoimmune encephalomyelitis (EAE) in Dark Agouti (DA) rats.

Cerebrospinal fluid proteins and free amino Acids in patients with solvent induced chronic toxic encephalopathy and healthy controls.
Occupational and Environmental Medicine, 1990Co-Authors: Bente E. Moen, B A Engelsen, Kyvik Kr, Trond RiiseAbstract:The concentrations of protein, albumin, IgG, and free amino Acids in the cerebrospinal fluid of 16 patients with chronic toxic encephalopathy due to organic solvents were measured. The patient group consisted of all patients with this diagnosis in a neurological department in 1985. The diagnosis was based on neuraesthenic symptoms, pathological psychometric performance, and verified exposure to neurotoxic organic solvents. A control group of 16 patients with myalgias or backache, or both, and no signs of disease was used for comparison. The purpose was to study possible changes in the cerebrospinal fluid that might contribute to understanding the aetiology of solvent induced chronic toxic encephalopathy. A rise in protein, albumin, and IgG was found in the patient group compared with the control group, as well as reduced concentrations of phosphoethanolamine, taurine, homocarnosine, ethanolamine, Alpha-Aminobutyric Acid, and leucine. Using a stepwise multiple regression analysis, taurine was negatively correlated to exposure to solvents. These findings may indicate membrane alterations in the central nervous system related to exposure to organic solvents.
