Herein we describe a comprehensive RNA-Seq analysis of feet and lymph nodes at peak viraemia (day 2 post infection), acute arthritis (day 7) and chronic disease (day 30) in the CHIKV adult wild-type mouse model. Genes previously shown to be up-regulated in CHIKV patients were also up-regulated in the mouse model. CHIKV sequence information was also obtained with up to ?8% of the reads mapping to the viral genome; however, no adaptive viral genome changes were apparent. Although day 2, 7 and 30 represent distinct stages of infection and disease, there was a pronounced overlap in up-regulated host genes and pathways. Type I interferon response genes (IRGs) represented up to ?50% of up-regulated genes, even after loss of type I interferon induction on days 7 and 30. Bioinformatic analyses suggested a number of interferon response factors were primarily responsible for maintaining type I IRG induction. A group of genes prominent in the RNA-Seq analysis and hitherto unexplored in viral arthropathies were granzymes A, B and K. Granzyme A-/- and to a lesser extent granzyme K-/-, but not granzyme B-/-, mice showed a pronounced reduction in foot swelling and arthritis, with analysis of granzyme A-/- mice showing no reductions in viral loads but reduced NK and T cell infiltrates post CHIKV infection. Treatment with Serpinb6b, a granzyme A inhibitor, also reduced arthritic inflammation in wild-type mice. In non-human primates circulating granzyme A levels were elevated after CHIKV infection, with the increase correlating with viral load. Elevated granzyme A levels were also seen in a small cohort of human CHIKV patients. Taken together these results suggest granzyme A is an important driver of arthritic inflammation and a potential target for therapy.Trial Registration: ClinicalTrials.gov NCT00281294 Twit Text FOAVip RNA-Seq analysis of chikungunya virus infection and identification of granzyme A as a major promoter of arthritic inflammation ????PLoS Pathog http://www.kidney.de/pget.php?&tw=1&pmid=28207896 #FOAvip Twit Text # Free Paper on # # # # # LINK http://www.kidney.de/pget.php?&tw=1&pmid=28207896 #FOAvip English Wikipedia <ref>{{Cite pmid|28207896}}</ref> RNA-Seq analysis of chikungunya virus infection and identification of granzyme A as a major promoter of arthritic inflammation #MMPMID28207896 Wilson JAC; Prow NA; Schroder WA; Ellis JJ; Cumming HE; Gearing LJ; Poo YS; Taylor A; Hertzog PJ; Di Giallonardo F; Hueston L; Le Grand R; Tang B; Le TT; Gardner J; Mahalingam S; Roques P; Bird PI; Suhrbier A PLoS Pathog 2017[Feb]; 13 (2): ä PMID28207896show ga Chikungunya virus (CHIKV) is an arthritogenic alphavirus causing epidemics of acute and chronic arthritic disease.
