Аннотация:Neutrophils release decondensed nuclear chromatin or Neutrophil Extracellular Traps (NETs) inresponse to a great number of physiological and pharmacological stimuli. However, apart from the hostdefensive function, NETs play an essential role in the pathogenesis of various autoimmune, inflammatory,and malignant diseases. Therefore, understanding the molecular mechanisms of NETs formation, usuallyleading to the neutrophil death (NETosis), is important to control the probable aberrant or excessive NETsrelease. The Src-family kinases (Src-kinases) are non-receptor tyrosine kinases that are involved in a variety of human functions. However, their role in NETosis and oxidative burst has not been sufficiently studied. Since three representatives of Src-kinases (Hck, Fgr, and Lyn) have been described in human neutrophils, we studied their contribution to NETosis and oxidative burst using inhibitory analysis. We have shown that Srckinases are involved in the oxidative burst and NETosis induced by the calcium ionophore A23187 but not the mimetic of diacylglycerol phorbol-12-myristate-13-acetate (PMA).
