Gaucher disease (GD) is an autosomal recessively inherited that belongs to the group of lysosomal storage diseases. In GD, there chronic activation macrophage system, disruption regulatory functions macrophages, a shift in cytokine regulation towards pro-inflammatory cytokines and development inflammation involving all immune cells, which can lead changes composition both major minor populations lymphocytes. Reduced beta-glucocerebrosidase activity impairs normal function autophagy, leading...

Autoimmune hepatitis (AIH) is a progressive hepatocellular inflammation of unknown etiology, accompanied by the process liver fibrosis. Damage in associated with formation highly reactive molecules that contain unpaired electrons (free radicals), which turn induce lipid peroxidation, leading to development mitochondrial dysfunction. Mitochondrial DAMPs released from damaged hepatocyte mitochondria (with mtDNA as main active component) directly activate hepatic stellate cells and cause...

In recent decades, there has been an increase in the incidence of autoimmune diseases (AID) among adults and children. The immunopathogenesis AID is based on imbalance between autoaggressive regulatory cells (Tregs), which regulated by metabolic signaling pathways cytokine microenvironment. Understanding mechanisms immunometabolism opens up new possibilities for treatment patients with AID. aim was to evaluate activity lymphocyte dehydrogenases associated OXPHOS glycolysis, depending level...
