Abstract

The Oropouche virus (OROV) is the etiological agent of Oropouche fever, a debilitating febrile illness common in South America. Despite its importance in public health, little is known about the biology of the virus in the host cell, especially the relationship between viral and cellular host protein. Our preliminary results from mass spectrometry analysis of the cellular proteome during OROV infection revealed several host proteins that are up or downregulated in response to the virus in human fibroblasts, including RNA polymerases, innate immunity signalling proteins and extracellular matrix proteins. The work proposed aims to elucidate the mechanism by which OROV modulates host proteins that are potentially involved in virus replication and pathogenesis and will complement my PhD study funded by FAPESP (2020/11900-6).
