Protein-protein interaction analysis using proteins related to the hemostasis pathway (hemostasis, platelet degranulation, complement and coagulation, and formation of fibrin clot) and immune system pathways (neutrophil degranulation, biosynthesis of amino acids, glycolysis/gluconeogenesis, post-translational protein phosphorylation) from chikungunya deaths compared with chikungunya survivors. Gene symbols (abbreviation names) for protein-coding genes followed the nomenclature approved by the HUGO Gene Nomenclature Committee.
