Abstract
NLRP3 inflammasome can be activated by a variety of stimuli and plays an important role in protecting host from pathogen invasion and maintaining homeostasis. However, the activation mechanism of NLRP3 inflammasome in fish is still unclear. In the present study, the NLRP3 gene (CcNLRP3) was identified from common carp, which was 3069 bp in length and encoded a protein with five domains. Sequence analysis showed that NLRP3 was evolutionarily conserved, and CcNLRP3 was closely related to that in grass carp and zebrafish. Real-time PCR showed that CcNLRP3 was widely expressed in various immune-related tissues of healthy common carp, and significantly increased after stimulation with E. tarda, A. hydrophila and Cyprinus spring viremia virus (SVCV), suggesting that CcNLRP3 might be involved in the immune defense of common carp. The results of co-IP, spot formation, oligomerization and fluorescence localization showed that CcNLRP3 could interact with CcASC and assemble into inflammasome. The cytotoxicity assays showed that CcNLRP3 inflammasome was involved in the pyroptosis induced by CcGSDME. At the same time, CcNLRP3 could directly interact with CcCaspase-A/B and result in increased Caspase-B enzyme activity and LDH release, indicating that CcNLRP3 could also form inflammasome through ASC-independent pathway. Taken together, the results provide targets and theoretical basis for the prevention and control of infectious diseases in aquaculture.

Abstract
EF-hand proteins not only regulate biological processes, but also influence immunity and infection. In this review, we summarize EF-hand proteins' functions in host and zoonotic pathogens, with details in structures, Ca2+ affinity, downstream targets and functional mechanisms. Studies entitled as EF-hand-related but with less solid features were also discussed. We believe it could raise cautions and facilitate proper research strategy for researchers.

Pathogenicity and anti-infection immunity of animal H3N2 and H6N6 subtype influenza virus cross-species infection with tree shrews. Virus Res 2023; 324:199027.

Abstract
Animal influenza viruses can spread across species and pose a fatal threat to human health due to the high pathogenicity and mortality. Animal models are crucial for studying cross-species infection and the pathogenesis of influenza viruses. Tupaia belangeri (tree shrew) has been emerging as an animal model for multiple human virus infections recently because of the close genetic relationship and phylogeny with humans. So far, tree shrew has been reported to be susceptible to human influenza virus subtype H1N1, avian influenza viruses subtype H9N2, subtype H5N1, and subtype H7N9. However, the pathogenicity, infection, and immunity of swine and land avian influenza viruses with low pathogenicity and the potential to jump to humans remain largely unexplored in the tree shrew model. Previously, our team has successfully isolated the newly emerging swine influenza virus subtype H3N2 (A/Swine/GX/NS2783/2010, SW2783) and avian influenza virus subtype H6N6 (A/CK/ZZ/346/2014, ZZ346). In this study, we observed the pathogenicity, immune characteristics, and cross-species infection potential ability of SW2783 and ZZ346 strains in tree shrew model with 50% tissue culture infective dose (TCID50), hematoxylin and eosin (HE) staining, immunohistochemistry (IHC), real-time quantitative PCR (qRT-PCR) and other experimental methods. Both animal-borne influenza viruses had a strong ability on tissue infection in the turbinate and the trachea of tree shrews in vitro, in which SW2783 showed stronger replication ability than in ZZ346. SW2783 and ZZ346 both showed pathogenic ability with infected tree shrews model in vivo without prior adaptive culture, which mainly happened in the upper respiratory tract. However, the infection ability was weak, the clinical symptoms were mild, and the histopathological changes in the respiratory tract were relatively light. Furthermore, innate immune responses and adaptive immunity were observed in the tree shrew model after the infection of SW2783 and ZZ346 strains. We observed that the unadapted SW2783 and ZZ346 virus could transmit among tree shrews by direct contact. We also observed that SW2783 virus could transmit from tree shrews to guinea pigs. These results indicated that both animal-borne influenza viruses could induce similar pathogenicity and immune response to those caused by human-common influenza viruses. Tree shrews may be an excellent animal model for studying the interaction between the influenza virus and the host and the cross-species infection mechanism of the animal influenza virus.
