Associations of IL23R, BMP6 and PTGS1 Polymorphisms with Radiographic Severity of Ankylosing Spondylitis
Background/Purpose: Ankylosing spondylitis (AS) is an inflammatory disease affecting spine which may lead to new bone formation and disability. However, the radiographic severity of AS…Abstract Number: 2819 • 2015 ACR/ARHP Annual Meeting
Rorc Antagonism Inhibits IL-23-Dependent Aberrant Bone Formation in Vivo
Background/Purpose: RORγt is a nuclear hormone receptor expressed in Th17 cells and distinct subsets of lymphoid cells, including innate lymphoid cells (ILC), and γδ T-cells.…Abstract Number: 2820 • 2015 ACR/ARHP Annual Meeting
Multi-Omics Studies of Gut Microbiota in Enthesitis-Related Arthritis Identify Diminished Microbial Diversity and Altered Typtophan Metabolism As Potential Factors in Disease Pathogenesis
Background/Purpose: Children with enthesitis-related arthritis (ERA) and adults with spondyloarthritis are at risk for intestinal inflammation. We have previously shown altered microbiota in children with…Abstract Number: 2821 • 2015 ACR/ARHP Annual Meeting
Increased CD4 T Cell GM-CSF Production in Spondyloarthritis
Background/Purpose: Immunological, genetic and therapeutic studies have implicated the IL-17A/IL-23 inflammatory axis in SpA. GM-CSF is emerging as a cytokine that marks out a pathogenic…Abstract Number: 2822 • 2015 ACR/ARHP Annual Meeting
