The research goals by Marcelino JM includes isolation of HIV-1 and HIV-2 isolates, expression, purification and characterization of HIV envelope peptides, epitopes mapping, neutralizing antibodies response evaluation in infection by HIV-1 and HIV-2 and HIV vaccines development. Marcelino, JM is author/co-author of 14 peer-reviewed publications and many presentations in international meetings.
