    Microbiota-Dependent Signals Regulate Inflammatory Myelopoiesis in a Murine Model of Macrophage Activation Syndrome

    Lehn K. Weaver1, Chhanda Biswas1, Niansheng Chu1 and Edward M. Behrens2, 1Pediatric Rheumatology, Children's Hospital of Philadelphia, Philadelphia, PA, 2Rheumatology, Children's Hospital of Philadelphia, Philadelphia, PA

    Enhanced Myelopoiesis Downstream of Toll-like Receptor 9 Activation Drives a Feed-Forward Inflammatory Response

    Lehn K. Weaver1 and Edward M. Behrens2, 1Pediatric Rheumatology, Children's Hospital of Philadelphia, Philadelphia, PA, 2Pediatric Rheumatology, Childrens Hospital of Philadelphia, Philadelphia, PA

    Background/Purpose: Monocytes are myeloid cells important for the initiation of inflammation and have been implicated in the pathogenesis of autoimmunity. Monocytes interact with their environment…
