With a new publication in Arthritis Research and Therapy, entitled “Ectopic bone formation and systemic bone loss in a transmembrane TNF-driven model of human spondyloarthritis”, Biomedcode in collaboration with George Kollias Lab at BSRC Al. Fleming, introduce the TgA86 transmembrane TNF transgenic mouse as a novel model of human spondyloarthritis (SpA).
The authors show that the TgA86 mouse model develops spontaneously peripheral arthritis and axial pathologies that closely reproduce key pathogenic features of human SpA, including distinct stages of inflammation and ectopic new bone formation. This is a chronic and complex disease model that similar to human patients also develops extraarticular comorbidities such as heart valve pathology and systemic bone loss. As with human patients in the clinic, all the pathologies of the TgA86 mouse model are reversed following early treatment with anti-hTNF therapeutics.
This novel model of SpA that captures not only specific features, but also the complexity of human disease, can prove to be an invaluable translational tool in the study of SpA pathogenesis as well as in the evaluation of human therapeutics. Read More
