Abstract: Human parainfluenza viruses (hPIVs), a series of single-stranded RNA viruses of Paramyxoviridae, are the main pathogen of respiratory tract infection. hPIV3 is the main cause of lower respiratory tract infection leading to bronchiolitis and pneumonias in young children under the age of six months, and it is the second major pathogen only next to respiratory syncytial virus (RSV). In this paper, we mainly discuss two kinds of virulence-related surface glycoprotein of hPIV3: hemagglutinin-neuraminidase (HN) protein and fusion protein (F) by briefly introducing the protein structure and physiological functions of HN and F. According to the latest research progress, we focus on the models which have been postulated to explain how F and HN work in concert to bring about membrane fusion.
