Abstract Although reports of human infection with influenza A(H5N6) increased in 2021, similar H5N6 virus poultry are few. We detected 10 avian clade 2.3.4.4b viruses from 4 provinces China. The showed strong immune-escape capacity and complex genetic reassortment, suggesting further transmission risk.

Inflammasomes are one kind of important innate immune defense against viral and bacterial infections. Several inflammasome-forming sensors detect molecular patterns invading pathogens then trigger inflammasome activation and/or pyroptosis in infected cells, viruses employ unique strategies to hijack or subvert activation. Infection with herpesviruses induces the diverse inflammasomes, including AIM2 IFI16 inflammasomes; however, how Kaposi's sarcoma-associated herpesvirus (KSHV) counteracts...

Due to the high dynamic characteristics of low-orbit satellite networks, frequent handovers users led heavy mobility management load and large handover delay. To solve these problems, one mechanism based on virtual agent domain (VAD) is proposed. In this mechanism, a cluster (VAC) designed co-manage network architecture in corresponding VAD. With on-board processing switching capabilities, distributed adopted support information sharing between VACs, which reduces performance requirements...
