Dengue virus (DENV) is a major emerging arthropod-borne pathogen, which infects individuals in both subtropical and tropical regions. Patients with DENV infection exhibit evidence of hepatocyte injury. However, the mechanisms of hepatocyte injury are unclear. Therefore we examined the expression of cell death genes during DENV-infection of HepG2 cells using(More)
Hepatic dysfunction is a well recognized feature of dengue virus (DENV) infection. However, molecular mechanisms of hepatic injury are still poorly understood. A complex interaction between DENV and the host immune response contributes to DENV-mediated tissue injury. DENV capsid protein (DENV C) physically interacts with the human death domain-associated(More)
Dengue fever (DF), dengue hemorrhagic fever (DHF), and dengue shock syndrome (DSS), caused by dengue virus (DENV) infection, are important public health problems in the tropical and subtropical regions. Abnormal hemostasis and plasma leakage are the main patho-physiological changes in DHF/DSS. A remarkably increased production of cytokines, the so called(More)
Dengue virus (DENV) infection is one of the most important mosquito-borne viral diseases, which is endemic in the tropical and sub-tropical regions. Patients with dengue hemorrhagic fever (DHF) generally present hemorrhagic tendencies, plasma leakage, thrombocytopenia, and hemoconcentration. Hepatic dysfunction is also a crucial feature of DENV infection.(More)
Hepatic injury in dengue virus (DENV) infection is authenticated by hepatomegaly and an upsurge in transaminase levels. DENV replicates in hepatocytes and causes hepatocyte apoptosis both in vitro and in vivo. Understanding the molecular mechanisms of DENV-induced hepatic injury could facilitate the development of alternate chemotherapeutic agents and(More)
Dengue Virus (DENV) infection is an important mosquito-borne viral disease and its clinical symptoms range from a predominantly febrile disease, dengue fever (DF), to dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS). Increased levels of cytokines - the so-called 'cytokine storm', contribute to the pathogenesis of DHF/DSS. In this study, we(More)
The liver is considered to be an important organ of dengue virus (DENV) replication and pathogenesis. However, molecular mechanisms of hepatic injury are still poorly understood. Modulation of Mitogen Activated Protein Kinases (MAPKs) was previously shown to affect DENV-induced apoptosis of hepatocytes in vitro. However, the in vivo role of ERK1/2, a member(More)
