OBJECTIVE Increasing evidence suggests that miRNAs have a profound impact on host defense to Hepatitis C virus (HCV) infection and clinical outcome of standard HCV therapy. In this study, we investigated modulation of miRNA expression in Huh7.5 hepatoma cells by HCV infection and in vitro interferon-αtreatment. METHODS MiRNA expression profiling was determined using Human miRNA TaqMan® Arrays...

Pegylated interferon alpha (Peg IFN-α) in combination with ribavirin is the backbone of treatment in chronic hepatitis C (CHC). Cardiotoxicity due to interferon therapy is rare. The most frequent cardiovascular complications are arrhythmias and ischemic manifestations. Cardiomyopathy is extremely rare but can be life threatening. We present the case of a 41-year-old female patient with CHC in w...

BACKGROUND Valproic acid (VPA) acts as a specific inhibitor of class I HDACs and it use has been proven to be safe since a long time. MATERIALS AND METHODS In the present study, we investigated the effect of VPA in the combination with pegylated interferon-α (PEG-IFNα) in inhibition of cell proliferation of human pancreatic cancer cell lines. RESULTS VPA enhanced the effect of PEG-IFNα, and...

Most patients with human immunodeficiency virus (HIV) who remain CD4(+) T-cell deficient on antiretroviral therapy (ART) exhibit marked immune activation. As CD4(+) T-cell activation may be mediated by microbial translocation or interferon-alpha (IFN-α), we examined these factors in HIV patients with good or poor CD4(+) T-cell recovery on long-term ART. Messenger RNA levels for 3 interferon-sti...

Plasmacytoid dendritic cells (pDCs) were initially identified as the prominent natural type I interferon-producing cells during viral infection. Over the past decade, the aberrant production of interferon α/β by pDCs in response to self-derived molecular entities has been critically implicated in the pathogenesis of systemic lupus erythematosus and recognized as a general feature underlying oth...
