PROPHYLAXIS OF TYPE ² DIABETES
MELLITUS: PATHOPHYSIOLOGICAL
SUBSTANTIATION, STRATEGY
AND CLINICAL REALIZATION
V.V. Poltorack, N.I. Gorbenko, E.A. Sakalo
Summary. This article contains the analyses of literature data about the possibilities of immune prophylaxis
and immune therapy of patients with type 1 diabetes mellitus, the main aim of which is to prevent or to stop the
autoimmune destruction of pancreatic beta-cells. The
authors describe the modern state of pathophysiological
ground for this therapeutical approach.
Key words: type I diabetes mellitus, immune pathogenesis, immune prophylaxis.
