The silkworm (Bombyx mori) is an economically important insect and a lepidopteran model organism. Controlling viral infections is crucial for the sustainable development of sericulture. Bombyx mori nucleopolyhedrovirus (BmNPV) infection can cause large-scale mortality in silkworm populations. Ins...
This study identifies grass carp TLR4bb as a crucial hub coordinating antiviral immunity with heme metabolism, redox balance, and gut microbiota during GCRV-II infection. While TLR4bb recruits TIRAP/MyD88/TRIF to activate IFN signaling against the virus, its synergy with heme and viral sensing tr...
