Six pairs of transcription profiles between glycopeptide-intermediate S. aureus (GISA [or vancomycin-intermediate S. aureus; VISA]) and glycopeptide-susceptible S. aureus (vancomycin-susceptible S. aureus [VSSA], including glycopeptide-susceptible isogenic mutants from VISA) strains were compared using a microarray. Ninety-two open reading frames which were(More)
BACKGROUND & AIMS T-helper (Th)17 cells that secrete interleukin (IL)-22 have immunomodulatory and protective properties in the liver and other tissues. IL-22 induces expression of proinflammatory genes but is also mitogenic and antiapoptotic in hepatocytes. Therefore, it could have multiple functions in the immune response to hepatitis B virus (HBV). (More)
Toll-like receptors (TLRs) 2 and 4 play a key role in chronic hepatitis B virus (HBV) infection. However, the role of TLRs in the pathogenesis of HBV-related liver cirrhosis and their regulation of the innate immune response of patients with liver cirrhosis remain unknown. To assess the contribution of TLR2/4 in HBV-related liver cirrhosis, we examined the(More)
BACKGROUND/AIM There is very limited experience in the management of telbivudine (LdT)-associated virological breakthrough (VBT) and resistance in the treatment of chronic hepatitis B (CHB) patients, and the guideline recommendations are primitively based on the general principles of rescue therapy to nucleos(t)ide analog resistance. The aim of this study(More)
As an aggressive pathogen, Staphylococcus aureus poses a significant public health threat and is becoming increasingly resistant to currently available antibiotics, including vancomycin, the drug of last resort for gram-positive bacterial infections. S. aureus with intermediate levels of resistance to vancomycin (vancomycin-intermediate S. aureus [VISA])(More)
CXCR4 plays an essential role as the first discovered coreceptor for the entry of T cell tropic isolates of HIV-1. Blocking the surface expression of this receptor may be a potential strategy to prevent HIV-1 infection. A lentiviral vector, pLenti6/V5-S-K, expressing a SDF-KDEL fusion protein was constructed and a replication-incompetent lentiviral stock(More)
RNA interference might be an efficient antiviral therapy for some obstinate illness. Here, we studied the effects of hepatitis B virus (HBV)-specific 21-nt small interfering RNAs (siRNA) on HBV gene expression and replication in 2.2.15 cells. Seven vectors expressing specific hairpin siRNA driven by the RNA polymerase II-promoter were constructed and(More)
Chronic hepatitis B is characterized by an impaired immune response to hepatitis B virus (HBV). Telbivudine treatment has significantly improved the clinical outcome of chronic HBV infection. However, the underlying mechanism behind the antiviral response of patients treated with nucleoside analogs remains unclear. To gather more evidence about the(More)
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(More)
Hantaan virus (HTNV), the prototype member of the Hantavirus genus in the family Bunyaviridae, causes hemorrhagic fever with renal syndrome (HFRS), which is characterized by capillary leakage, hemorrhage, and renal injury, and is an important public health problem in China. Some kinds of immune cells, particularly CD8(+) T cells, are involved in the(More)
