BACKGROUND Previous studies in patients with hepatitis C virus (HCV)/HIV coinfection have shown that the presence of GBV-C is associated with significantly less compensated and decompensated cirrhosis, and an improvement in cirrhosis-free survival. OBJECTIVES This study aimed to describe the effect of GBV-C in patients with chronic hepatitis C and HIV coinfection. PATIENTS AND METHODS We re...
INTRODUCTION Persistent infection with GBV-C (GB Virus C), a non-pathogenic virus related to hepatitis C virus (HCV), prolongs survival in HIV infection. Two GBV-C proteins, NS5A and E2, have been shown previously to inhibit HIV replication in vitro. We investigated whether the GBV-C NS3 serine protease affects HIV replication. RESULTS GBV-C NS3 protease expressed in a human CD4+ T lymphocyte...
UNLABELLED Naturally occurring Newcastle disease virus (NDV) strains vary greatly in virulence. The presence of multibasic residues at the proteolytic cleavage site of the fusion (F) protein has been shown to be a primary determinant differentiating virulent versus avirulent strains. However, there is wide variation in virulence among virulent strains. There also are examples of incongruity bet...
