Reperfusion injury (RI), a potential life-threatening disorder, represents an acute inflammatory response after periods of ischemia resulting from myocardial infarction, stroke, surgery, or trauma. The recent identification of a monoclonal natural IgM that initiates RI led to the identification of nonmuscle myosin heavy chain type II A and C as the self-targets in two different tissues. These results identify a novel pathway in which the innate response to a highly conserved self-antigen expressed as a result of hypoxic stress results in tissue destruction.
Abbreviations used: ANOVA, analysis of variance; Hc, heavy chain; HRP, horseradish peroxidase; MBL, mannan-binding lectin; NMHC-II, nonmuscle myosin Hc type II; PARS, poly(ADP ribose) synthetase; PL, phospholipd; RI, reperfusion injury; ROS, reactive oxygen species; SPR, surface plasmon resonance.
