H9N2 avian influenza virus circulates widely in poultry and has been responsible for sporadic human infections in several regions. Few studies have been conducted on the pathogenicity of H9N2 AIV isolates that have different genomic features. We compared the pathology induced by a novel reassortant H9N2 virus and two currently circulating H9N2 viruses that have different genomic features in ferrets...
The significance of TLR expression and Tregs in HBV infection has not been clearly described. In this report, flow cytometry was performed to assess TLR2/4 expression on monocytes and circulating CD4 + CD25 + CD127 low/− Tregs frequency of 16 acute hepatitis B (AHB), 42 chronic hepatitis B (CHB), 22 asymptomatic HBV carriers (AsC), and 20 normal controls (NC). We found that...
Hantaan virus (HTNV) infects endothelial cells and is associated with increased vascular permeability during hemorrhagic fever with renal syndrome (HFRS). The pattern of increased vascular permeability is mediated by immune response. Therefore, it is necessary to characterize the mechanism of HTNV involvement in the host's innate immune. In this study, the expression of five toll-like receptors (TLRs)...
