Research/Clinical Interest
The BXD2 autoimmune mouse model of lupus and erosive arthritis; Anti-DR5 as a novel therapy for lupus
Two major studies are currently ongoing in my laboratory: 1. We have identified that autoimmune BXD2 mice exhibit unique features, including spontaneous formation of germinal centers, increased expression of activation-induced cytidine deaminase (AID), increased production of pathogenic autoantibodies that are polyreactive, significantly increased percentage of IL-17+ CD4 TH cells (TH-17) and IL-17R+ B cells, and significantly increased numbers of type I interferon producing plasmacytoid dendritic cells in the spleens of these mice. We are currently studying the interconnection of high IL-17, high type I IFN and the development of spontaneous germinal centers in these mice. 2. We are developing a new lupus mouse models to study the safety and efficacy of using an anti-human DR5 antibody (TRA-8) as novel therapy of lupus and other autoimmune diseases. Death receptor 5 (DR5) is a cell surface receptor for tumor necrosis factor-related apoptosis-inducing ligand (TRAIL). Investigators at UAB (Dr. Tong Zhou and colleagues) have generated a unique anti-human DR5 antibody (TRA-8) that triggers the death of DR5+ cells. TRA-8 was selected due to its signaling of apoptosis (differing from TRAIL, which can induce proliferation). We have found that it kills cultured human lupus CD4+ T cells and plasma B cells. We have developed a transgenic mouse model that expresses a Floxed-STOP humanized DR5 mouse transgene (hu/mo DR5 Tg) and will express this hu/mo DR5 Tg in T and B cells in autoimmune mice that develop lupus-like disease. The ongoing project is to test the method of action and effectiveness of TRA-8 in depleting autoreactive CD4 T and plasma B cells, and its safety, in a special humanized mouse model, to determine its potential utility as a therapy for patients with lupus.
