    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.

    Rendering virus particles more infectious. This study reveals an unexpected reciprocal role of a cellular receptor tyrosine kinase regulating DENV RNA repli-cation and the production of infectious virions. INTRODUCTION Dengue fever, hemorrhagic fever, and shock syndrome caused by infection with the dengue virus DENV are among the most Inhibition of the TNFα receptor was also reported in U937 monocytic cells treated with chloroquine. In the Dengue virus model, chloroquine was found to inhibit interferon-alpha IFNα, IFNβ, IFNγ, TNFα, IL-6 and IL-12 gene expression in U937 cells infected with Dengue-2 virus. 5. Conclusion 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.

    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. Protein kinase signaling plays a role in their anti-Mtb activity.6 Another class of approved kinase inhibitors demonstrating a broad antimicrobial coverage is the cellular Abelson tyrosine kinase c-Abl inhibitors, such as imatinib and nilotinib. These drugs inhibit replication of Ebola virus EBOV, dengue virus 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.

    Plaquenil and skin discoloration - Sjogren's World Apr 18, 2009 I've been on Plaquenil 400mg a day for almost 4 years. I haven't noticed any skin discoloration but my hair turned grey at a very young age and I've always kept it natural, but as of late it is turning yellowish and my hair dresser thinks it is from the medication.
