When the expression of NOS2 in M1-polarized macrophages is induced, huge amounts nitric oxide (•NO) are produced from arginine and molecular oxygen as substrates. While anti-microbial action primary function M1 macrophages, excessive activation may result inflammation being aggravated. The reaction •NO with superoxide produces peroxynitrite, which highly toxic to cells.

Atherosclerosis is a complex inflammatory process associated with high-mortality cardiovascular diseases. Today, there growing body of evidence linking atherosclerosis to mutations mitochondrial DNA (mtDNA). But the mechanism this link insufficiently studied. progression involves different cell types and macrophages are one most important. Due their high plasticity, can demonstrate pro-inflammatory pro-atherogenic (macrophage type M1) or anti-inflammatory anti-atherogenic M2) effects. These two types, formed as result external stimuli, differ significantly in metabolic profile, which suggests central role mitochondria implementation macrophage polarization route. According this, we assume that mtDNA causing disturbances play an internal trigger, leading formation M1 M2. This review provides comparative analysis characteristics function possible associations linked inflammation-based pathologies including atherosclerosis.
