| 1 | Regulation of innate immune responses by rabies virus显示文摘Rabies virus(RABV)is an infectious and neurotropic pathogen that causes rabies and infects humans and almost all warm-blooded animals,posing a great threat to people and public safety.It is well known that innate immunity is the critical first line of host defense against viral infection.It monitors the invading pathogens by recognizing the pathogen-associated molecular patterns and danger-associated molecular patterns through pattern-recognition receptors,leading to the production of type I interferons(IFNα/β),inflammatory cytokines,and chemokines,or the activation of autophagy or apoptosis to inhibit virus replication.In the case of RABV,the innate immune response is usually triggered when the skin or muscle is bitten or scratched.However,RABV has evolved many ways to escape or even hijack innate immune response to complete its own replication and eventually invades the central nervous system(CNS).Once RABV reaches the CNS,it cannot be wiped out by the immune system or any drugs.Therefore,a better understanding of the interplay between RABV and innate immu-nity is necessary to develop effective strategies to combat its infection.Here,we review the innate immune responses induced by RABV and illustrate the antagonism mechanisms of RABV to provide new insights for the control of rabies. | Haili Zhang Jingbo Huang Yumeng Song Xingqi Liu Meichen Qian Pei Huang Yuanyuan Li Ling Zhao Hualei Wang | 2022 | Animal Models and Experimental Medicine2022，5，5： | 2 |
| 2 | Incorporation of Escherichia coli heat-labile enterotoxin B subunit into rabies virus particles enhances its immunogenicity in mice and dogs显示文摘Although inactivated vaccines against rabies have the advantage of high safety,effective protection against rabies virus(RABV)infection often requires multiple,high-dose immunization.Incorporating a molecular adjuvant into the viral particles has been found to be a useful strategy to promote the immune effectiveness of inactivated vaccines.In this study,we constructed a recombinant virus,rCVS11-LTB,which chimerically expresses a molecular adjuvant heat-labile enterotoxin B subunit(LTB)protein on the surface of the RABV particles.Immunogenicity in vivo was found to be promoted by rCVS11-LTB through the activation of dendritic cells(DCs).Our results demonstrated that inactivated rCVS11-LTB was able to induce higher levels of virusneutralizing antibodies(VNAs)in both mice and dogs than the parent virus rCVS11,to enhance the cellular immune response and T cell immune memory in mice,and was also able to provide 100%protection in mice from lethal doses of rabies virus,indicating its potential as a safe and effective inactivated rabies vaccine candidate. | Zhiyuan Gong Hailun Li Meichen Qian Yujie Bai Hongli Jin Jingxuan Sun Mengyao Zhang Cuicui Jiao Pei Huang Yuanyuan Li Haili Zhang Hualei Wang | 2023 | Biosafety and Health2023，5，5： | 0 |
| 3 | Global patterns of taxonomic and phylogenetic diversity of flowering plants: Biodiversity hotspots and coldspots显示文摘Species diversity of angiosperms(flowering plants) varies greatly among regions.Geographic patterns of variation in species diversity are shaped by the interplay of ecological and evolutionary processes.Here,using a comprehensive data set for regional angiosperm floras across the world,we show geographic patterns of taxonomic(species) diversity,phylogenetic diversity,phylogenetic dispersion,and phylogenetic deviation(i.e.,phylogenetic diversity after accounting for taxonomic diversity) across the world.Phylogenetic diversity is strongly and positively correlated with taxonomic diversity;as a result,geographic patterns of taxonomic and phylogenetic diversity across the world are highly similar.Areas with high taxonomic and phylogenetic diversity are located in tropical regions whereas areas with low taxonomic and phylogenetic diversity are located in temperate regions,particularly in Eurasia and North America,and in northern Africa.Similarly,phylogenetic dispersion is,in general,higher in tropical regions and lower in temperate regions.However,the geographic pattern of phylogenetic deviation differs substantially from those of taxonomic and phylogenetic diversity and phylogenetic dispersion.As a result,hotspots and coldspots of angiosperm diversity identified based on taxonomic and phylogenetic diversity and phylogenetic dispersion are incongruent with those identified based on phylogenetic deviations.Each of these metrics may be considered when selecting areas to be protected for their biodiversity. | Hong Qian Jian Zhang Meichen Jiang | 2023 | Plant Diversity2023，45，3： | 0 |
