Background

Human Respiratory Syncytial Virus (HRSV) is a negative-sense single-stranded RNA virus that belongs to the Paramyxoviridae family and the Pneumovirinae subfamily, and considered the most important pathogen causing respiratory disease in infants and neonates worldwide. The nucleoprotein of HRSV, a canonical cytosolic protein, is highly conserved among pneumoviruses and interacts with viral RNA, generating a helicoidal nucleocapsid which is responsible for genome and anti-genome resistance to RNase. In addition, the nucleoprotein could be responsible for inhibiting T-cell activation during infection by HRSV, and expressed on the surface of epithelial and dendritic cells, preventing immunological synapse assembly by naïve CD4+ T cells. Therefore, this protein is defined as a major virulence factor that contributes to impairing acquired immunity and enhances susceptibility to reinfection by HRSV.
