ABSTRACT.
Severe fever with thrombocytopenia syndrome virus (SFTSV), Heartland virus (HRTV) and Guertu virus (GTV) belong to the severe fever with thrombocytopenia syndrome/Heartland group of genus Bandavirus in the family Phenuiviridae of order Bunyavirales. Severe fever with thrombocytopenia syndrome virus and HRTV, identified from ticks from Asia and America, respectively, are important pathogens causing severe febrile diseases in humans. Guertu virus, closely related to these two viruses, is a potential pathogen, but no confirmed infection has been identified. So far, human-derived neutralizing monoclonal antibodies (mAbs) against SFTSV have been identified as having a great potential to be developed as antivirals; however, there is still a lack of neutralizing mAbs to GTV and HRTV. In this study, five neutralizing the mAbs against GTV and HRTV were obtained by hybridoma screening technology, four of which (14B4, 14D8, and 20D4 derived from GTV, and 27C8 derived from HRTV) showed cross reactivity and neutralization to all three viruses, and one derived from HRTV (10D6) neutralized HRTV specifically. The possible mechanisms of mAbs cross neutralization among the three viruses are discussed by analyzing their glycoprotein (GP) sequences and structures. Generating these neutralizing mAbs provides important antiviral candidates against GTV, HRTV, and SFTSV despite their differential activities, and their protective effect could be further evaluated in virus-infected mice. Their differential neutralizing efficiency and specificity further suggested that the three viruses share common mechanisms on the basis of GP functioning, and that HRTV poses a unique mechanism that differs from the other viruses. These findings shed light on developing broad-spectrum antiviral strategies against bandaviruses and promoting an understanding of the bandavirus infection process.
