Prof. Yu firstly revealed the molecular mechanism of HIV-1 Vif (viral infection factor) protein, which used cellular protein to degrade the natural antiviral factors of host, and provided a new antiviral target for HIV nonstructural proteins, and opened up a new research field of virus defense mechanism against host. As the discoverer of Vpx and Vpr recognized in the International AIDS field, Yu Xiaofang's team took the lead in initiating international research on the mechanism of Vpx and Vpr protein breaking through the host's innate immune defense.
Over the years, Prof. Yu has studied virus replication, especially the molecular mechanism of HIV life cycle and virus pathogenesis. He has published 54 J Virol. articles with more than 4000 citations, including 15 JVI articles with single citation times of more than 100.
Prof. Yu has been engaged in enterovirus research for more than ten years, and published 22 papers on enterovirus, including cell host and microbe, NAR, J. Virol, EMG. Inf. DIS, viruses, etc. He isolated and identified several strains of cv-a16, cv-a6 and ev-a71 of Northeast China. established animal pathogenic model, vaccine strain screening, and worked over immune protection and virus host interaction.
