Objective: Dogs of the breed Nova Scotia duck tolling retriever (NSDTR) are prone to develop a disease complex in some aspects resembling human systemic lupus erythematosus (SLE). Peripheral blood mononuclear cells (PBMCs) from human SLE patients have an increased mRNA expression type I interferon (IFN) regulated genes. However, it is unknown whether diseased dogs also display the typical type I IFN signature. Methods: To test canine sera for their capacity to induce type I IFN response Mardin-Darby canine kidney (MDCK) cells were cultured with sera from healthy dogs (n=25), immune-mediated rheumatic disease (IMRD) dogs with anti-nuclear antibodies (ANA+) (n=30) or dogs with steroid responsive meningitis-arteritis (SRMA) (n=25). mRNA expression of the genes MX1, IFIT1 and CXCL10 was measured by quantitative Real Time PCR. Results: A highly significant (p=0.0009) increase in mRNA expression of the type I IFN responsive gene MX1 was detected in cells stimulated by sera from dogs with SRMA, but not from IMRD ANA+ dogs. Expression of IFIT1 was twice as high in cells stimulated by sera from dogs with SRMA compared to both healthy dogs and ANA+ dogs. The mean expression of CXCL10 was nearly ten times higher in cells stimulated by sera from SRMA dogs than by ANA+ dogs and four times higher compared to cells stimulated by control dogs. Conclusion: Presence of type I IFN in sera from diseased NSDTR dogs was found in this study. This implies that this canine model can be used for identification of pathways of importance for autoimmune disorders in humans and for testing of novel therapeutic approaches. Our results can also be a step on the way towards personalized drugs in these dogs.
