Alveolar macrophages play a critical role in initiating the immune response to inhaled pathogens and have been shown to be the first cell type infected following intranasal inoculation with several pathogens, including Francisella tularensis. In an attempt to further dissect the role of alveolar macrophages in the immune response to Francisella, we(More)
OBJECTIVE Poor cellular trafficking and suboptimal T-cell responses in liver, the hall marks of chronic hepatitis C virus (CHC) infection, might be attributed to defective antigen presentation. Controversy exists regarding role of myeloid dendritic cells (DCs) in CHC and response to antiviral treatment. This study examines functional status of DCs before(More)
Chronic hepatitis C infection poses a major global health predicament and appears to be potent threat to mankind. The treatment in wide use is interferon/ribavirin combination therapy which is generally effective in about 60-70 per cent of patients carrying genotype 3 and causes significant morbidity. The response to therapy is largely guided by limited(More)
BACKGROUND Cellular immune responses seem to prevail in acute hepatitis, whereas chronically infected patients demonstrate generally suppressed cellular immune responses and significantly greater antibody responses. AIM To study hepatitis B virus (HBV) specific T cell proliferative responses in HBV related liver diseases. METHODS We analyzed the T(More)
PURPOSE Nonalcoholic fatty liver disease (NAFLD) is characterized by the presence of elevated circulating endotoxin levels. The continuous presence of endotoxin might be responsible for inducing activation of the innate immune system resulting in chronic sub-clinical inflammation. This study examines the status of dendritic cells (DCs), an important(More)
