    Receptor tyrosine kinase dengue virus chloroquine

    Of the 90 unique tyrosine kinase genes identified in the human genome, 58 encode receptor tyrosine kinase proteins. Receptor tyrosine kinases are part of the larger family of protein tyrosine kinases, encompassing the receptor tyrosine kinase proteins which contain a transmembrane domain, as well as the non receptor tyrosine kinases which do not possess transmembrane domains.

    Discovered that inhibitors of the c-Src protein kinase exhibit a potent inhibitory effect on dengue virus serotypes 1–4 and murine flavivirus Modoc. Mechanism of action studies demon-strated that the c-Src protein kinase inhibitor dasatinib prevents the assembly of dengue virions within the virus-induced membra-nous replication complex. The risk of severe disease is augmented when dengue virus DENV is opsonized with non- or sub-neutralizing levels of antibodies that ligate Fc-gamma receptors FcγRs for enhanced entry and replication in monocytes, macrophages and dendritic cells. This phenomenon, termed antibody-dependent enhancement ADE. We screened a siRNA library targeting human tyrosine kinases in Huh-7 cells and identified c-terminal Src kinase Csk as one of the kinases involved in dengue virus replication. Knock-down of Csk expression by siRNAs or inhibition of Csk by an inhibitor reduced dengue virus RNA levels but did not affect viral entry.

    The extracellular N terminal region exhibits a variety of conserved elements including immunoglobulin (Ig)-like or epidermal growth factor (EGF)-like domains, fibronectin type III repeats, or cysteine-rich regions that are characteristic for each subfamily of RTKs; these domains contain primarily a ligand-binding site, which binds extracellular ligands, e.g., a particular growth factor or hormone. Most RTKs are single subunit receptors but some exist as multimeric complexes, e.g., the insulin receptor that forms disulfide linked dimers in the presence of hormone (insulin); moreover, ligand binding to the extracellular domain induces formation of receptor dimers.

  6. In influenza A virus IAV infection, protein kinase C–βII PKC-βII, a host serine-threonine kinase, promotes virus entry by stimulating EGFR internalization, which is a crucial step in hepatitis C virus HCV infection as well. The role of this kinase in internalization of other EGFR-dependent pathogens remains uncharacterized.

    Hepatitis C virus infection activates Abl kinase. A Huh7.5 cells were serum-starved for 16 h and then treated with either DMSO vehicle or 10 μM of imatinib for 2 h. Cells were either mock-infected or infected with Jc1 using an MOI of 5. Dengue virus is the causative agent of dengue fever, dengue hemorrhagic fever, and dengue shock syndrome. High rates of dengue virus replication and virion production are related to disease severity. To identify anti-DENV compounds, we performed cell-based ELISA testing to detect the level of DENV E protein expression. Jan 23, 2017 As an endosomal inhibitor, chloroquine blocks Toll‐like receptor TLR mediated activation of plasmacytoid dendritic cells pDC, and myeloid differentiation primary response gene 88 MyD88 signaling by the decrease in levels of the downstream signaling molecules, interleukin‐1 receptor associated kinase 4 IRAK‐4 and IFN regulatory factor 7 IRF‐7 and by the inhibition of IFN‐α synthesis Martinson et al. 2014. In addition to suppress pDC activation, the analogs also block.
