Professor Gong Cheng leads a research unit studying the mechanism of infection and transmission of mosquito-borne virus as well as its antiviral immunity. Multiple mosquito-borne flaviviruses such as Dengue (DENV), West Nile (WNV), Chikungunya virus (CHIKV) are the pathogens of particular interest. The overarching aim is to develop novel approaches to control mosquito-borne flaviviral diseases in nature by utilizing identified related host protein as intervention target.

·Research on DENV

Dr. Cheng, for the very first time, discovered the function of the non-structural protein-1 (NS1) of DENV in the arbovirus lifecycle process. The molecular mechanism of NS1 protein promoting virus infection of mosquitoes is clarified. The question of “how are mosquito-borne viruses effectively acquired from an infected host to a fed mosquito” is therefore answered. Through the modification of NS1 protein, the infection rate of mosquitoes can be reduced. Thus, both mosquitoes and animal infections are inhibited. This is a brand-new vaccine design strategy that can prevent dengue fever in human body and simultaneously block the transmission of the virus in nature through mosquitoes. Such NS1-based immunization vaccine strategy against Dengue virus transmission has obtained relevant patent authorization.

·Firstly clarified the mechanism of Zika virus outbreak

Dr. Cheng found that the NS1 protein also helps virus infection in mosquitoes. It is pointed out that the enhancement of NS1 secretability in infected hosts mediated by a mutation promotes ZIKV prevalence in mosquitoes through mosquito-host transmission lifecycle. The abovementioned research outcomes explain the outbreak of Zika virus in recent years.

·Vaccine Development

In terms of novel mRNA vaccines, an immune balance strategy is proposed to reduce the risk of vaccine failure caused by mutations during the spread of the virus. A vaccine vector to jointly induce protective humoral immunity and cellular immune response is designed.Parts of the research has applied for related patents.

In terms of nanoparticle vaccine research, we designed and proposed an "assembled" broad-spectrum general vaccine research strategy, through the nanoparticle’s core externally coupled with single or multiple key vaccine antigens to achieve protection against major infectious diseases with multiple mutations or different sera type of viruses.
