The recent increase on arboviruses outbreaks in Brazil, mainly chikungunya (CHIKV) and mayaro (MAYV) in regions where malaria is endemic, has risen significantly the risk of co-infection. The three diseases induce strong inflammatory response in the host, resulting in complications such as prolonged arthralgia in CHIKV and MAYV infection, cerebral malaria and malaria associated Acute Respiratory Distress Syndrome caused by the malaria parasite. However, nothing is known about the impact co-infection has on the host response toward heterologous pathogens. This project aims to establish murine model of co-infection to study whether there is a cross-talk between the type of immune response induced by the virus and the malaria parasite, and how it will influence in the heterologous pathogens complications. The immunological and pathological indicators identified in these co-infection models allow the identification of possible disease biomarkers, as well as host factors that can be used as target for therapeutic drugs.
