Nucleoprotein (P40) is one of the most important proteins of Borna disease virus 1 (BoDV-1), but which proteins it would bind to in the pathogenesis of BoDV-1-infected hosts is unknown. We used lentivirus LV5-P40 overexpressing P40 to infect primary hippocampal neurons and characterized the interactome of P40 with co-immunoprecipitation (Co-IP) followed by mass spectrometry (MS) analysis. These interacting protein partners revealed the pathogenesis of BoDV-1-infected hosts. We also show for the first time that P40 interacts with 5HT2CR in rat neurons, which may be the molecular basis leading to neuropsychiatric diseases such as anxiety disorders and behavioral abnormalities after BoDV-1 infection of hosts.
