[The role of redox-dependent signal systems in the regulation of apoptosis under oxidative stress condition].

Programmed death of peripheral blood mononuclear cells from donors with acute inflammatory diseases (an acute appendicitis, a community-acquired pneumonia) was investigated under condition of oxidative stress in vitro and under effect of selective inhibitors of MAP-kinases JNK and p38. Levels of active and inactive forms of MAP-kinases, and factors of transcription were determined by immunoblotting (western blot analysis). The increase in the activity of apoptosis under condition of oxidative stress in vivo and during the acute inflammatory diseases is associated with the increase in the level of reactive oxygen species (ROS) in the cells.
