The key innate immune genes of tree shrew are genetically close to Homo sapiens. (A), The variation of coding amino acid of STING gene in tree shrew (Tupaia belangeri chinensis), and Homo sapiens. (B–D), Phylogenetic tree of STING (B), TLR3 (C) and MDA5 (D) gene of T. belangeri, H. sapiens, Macaca mulatta, Sus scrofa and Mus. The phylogenetic tree was constructed using the Maximum Likelyhood phylogeny test. Bootstrap values were set for 1,000 repetitions. (E, F) Viral replication of DENV-3 in Vero (E) and BM-MSCs (F) cells. DENV-3 genomic RNA was tested from 0 to 96 h post-inoculation in culture supernatants of Vero cells and tupaia BM-MSCs.
