Dr. Faria has been a Public Health researcher at the Oswaldo Cruz Foundation since 2007. For over 15 years, he has been working with the purinergic receptors, especially the P2X7R. Initially, it investigated only the mechanism of pore opening associated with P2X7R, one of the focuses of the project, and its intracellular signaling in different cell types. Subsequently, due to the lack of selective agonists and antagonists for this receptor, he started looking for new antagonists from natural or synthetic products with a focus on obtaining new molecules that can selectively act on the P2X7 receptor. Currently, they are studying the action of these molecules in animal models that induce stimuli to develop inflammatory diseases.
