Mechanisms of acute kidney injury induced by experimental Lonomia obliqua envenomation.

ABSTRACT: Lonomia obliqua caterpillar envenomation causes acute kidney injury (AKI), which can be responsible for its deadly actions. This study evaluates the possible mechanisms involved in the pathogenesis of renal dysfunction. To characterize L. obliqua venom effects, we subcutaneously injected rats and examined renal functional, morphological and biochemical parameters at several time points. We also performed discovery-based proteomic analysis to measure protein expression to identify molecular pathways of renal disease. L. obliqua envenomation causes acute tubular necrosis, which is associated with renal inflammation; formation of hematic casts, resulting from intravascular hemolysis; increase in vascular permeability and fibrosis. The dilation of Bowman's space and glomerular tuft is related
