Biography:

Sergey Suchkov was born in the City of Astrakhan, Russia, in a family of dynasty medical doctors. In 1980, graduated from Astrakhan State Medical University and was awarded with MD. In 1985, Suchkov maintained his PhD as a PhD student of the I.M. Sechenov Moscow Medical Academy and Institute of Medical Enzymology. In 2001, Suchkov maintained his Doctor Degree at the National Institute of Immunology, Russia.

From 1989 through 1995, Dr Suchkov was being a Head of the Lab of Clinical Immunology and Immunobiotechnology, Helmholtz Eye Research Institute in Moscow. From 1995 through 2004 - a Chair of the Dept for Clinical Immunology, Moscow Clinical Research Institute (MONIKI). In 1993-1996, Dr Suchkov was a Secretary-in-Chief of the Editorial Board, Biomedical Science, an international journal published jointly by the USSR Academy of Sciences and the Royal Society of Chemistry, UK.

Abstract

Abs against myelin basic protein (MBP), cardiac myosine (CM) and thyroid Ags (TPO, T3 and T4) endowing with proteolytic activity (Ab-proteases) are of great value to monitor chronic autoimmune inflammation and to thus illustrate the evolution of either of the above-mentioned autoimmune disorders. Ab-proteases from MS, AIM and AIT patients exhibited specific proteolytic cleavage of MBP, CM and thyroid Ags (T3, T3, TPO), respectively The activity of the Ab-proteases markedly differs between: (i) the patients and healthy controls, and (ii) different clinical courses, to to predict transformation prior to changes of the clinical course.

The activity of Ab-proteases was first registered at the subclinical stages 1-5 years (regardless to type of the disorder) prior to the clinical illness. Some (12-24%) of the direct disease-related relatives are seropositive for low-active Ab-proteases from which seropositive relatives established were being monitored for 2-3 years whilst demonstrating a stable growth of the Ab-associated proteolytic activity. We saw also low-active Ab-proteases in persons at MS-, AIM- and AIT-related risks (at the subclinical stages), and primary clinical, ultrasonic and MRT manifestations observed were coincided with the activity to have its mid-level reached. The activity of Ab-proteases would confirm a high subclinical and predictive value of the translational tools as applicable for personalized monitoring protocols. Ab-proteases can be programmed and re-programmed to suit the needs of the body metabolism. Of tremendous value are Ab-proteases directly affecting the physiologic remodeling of tissues with multilevel architecture. Further studies on targeted Ab-mediated proteolysis may provide a supplementary tool for predicting exacerbations and thus the disability of the MS, AIM and AIT patients.
