Abstract

Venomous fish are responsible for numerous accidents involving humans in the north and northeast regions of Brazil, Thalassophryne nattereri being the most common of them. T. nattereri venom causes chronic inflammation, impaired tissue repair and muscle necrosis in poisoned victims. In the inflammatory process, some cells such as neutrophils, monocytes and macrophages are recruited by inflammatory mediators for control and repair of the injury, but studies developed previously by our group show that the venom of T. nattereri develops an inappropriate cellular inflammatory response characterized by a reduced number of neutrophils at the site of injury. Neutrophil infiltration with subsequent apoptosis after elimination by macrophages is the prerequisite for the resolution of inflammation. IL-33 is released into the extracellular matrix after cell damage, mechanical or necrosis injury. IL-1b promotes the recruitment of neutrophils into inflamed sites. The objective of this study is to investigate the role of IL-33 and IL-1b in the control of heterogeneity and plasticity of the cellular response induced by T. nattereri venom.
