Abstract

Snakebite envenomation is recognized in category A of the Neglected Tropical Diseases by the World Health Organization (WHO) due to the worldwide burden of snakebite death and disability. Although the local effects of bites are well documented, knowledge on the systemic effects of snake venoms is limited. Envenomation by Viperidae snakes causes hypotension, ultimately leading to shock, coagulopathy, and kidney failure, but the mechanisms behind these effects remain broadly unknown. This mismatch between clinical and mechanistic knowledge makes it hard to find better interventions for severe envenoming with systemic effects. By using an integrative approach including quantitative proteomics, N-terminomics, and phosphoproteomics, in animals which will receive or not bothropic antivenom after Bothrops jararaca venom injection, we will analyze altered pathways in kidneys, liver, and lungs, with special focus on the activity of venom proteolytic enzymes.
