Autoantigens of Small Nerve Fibers and Human Coronavirus Antigens: Is There a Possibility for Molecular Mimicry?

In post-COVID-19 syndrome, clinical presentation of the nerve fiber dysfunction plays an important role. The possibility of autoantigen cross-mimicry of human coronaviruses and the peripheral nervous system needs to be investigated. The bioinformatic analysis was applied to search for possible common protein sequences located in the immunoreactive epitopes.

Molecular Mimicry between SARS-CoV-2 and Human Endocrinocytes: A Prerequisite of Post-COVID-19 Endocrine Autoimmunity?

Molecular mimicry between human and microbial/viral/parasite peptides is common and has long been associated with the etiology of autoimmune disorders provoked by exogenous pathogens. A growing body of evidence accumulated in recent years suggests a strong correlation between SARS-CoV-2 infection and autoimmunity. The article analyzes the immunogenic potential of the peptides shared between the SARS-CoV-2 spike glycoprotein (S-protein) and antigens of human endocrinocytes involved in most common autoimmune endocrinopathies.

Integration of Educational and Research Activities of Medical Students (Experience of the Medical Faculty of Saint Petersburg State University).

The article is devoted to the role of research activity of the medical students in higher education of physicians. The teaching of physicians in classical universities and specialized medical schools is compared. The history of physicians' training in Russia in imperial, Soviet and post-Soviet periods is reviewed and compared to development of higher medical education in other countries.
