Main tasks in the project and previous experience relevant to those tasks:
Task 1. Establishment of an inventory of biomaterial collected across Europe. Patients’ cohorts, DNA- and RNA-banks have been organized, including samples from synovial, bone marrow and kidney biopsies from a variety of autoimmune diseases. We will be contributing to the cohorts of SLE, RA, PsA and JIA for WP4.
Task 2. Organization of a structured inventory of existing clinical RA cohorts and registries as well as a large-scale pre-RA cohort, including pre-RA biological samples, and information on co-morbidities. The early arthritis, early –RA and RA clinical cohort includes the majority-if not all-of RA patients in the island of Crete (population 700,000). This represents a closed, homogenous population with very little external mobility. Through the Greek Biologic registry coordinated by our center we have access to a sizeable (approximately 5,000 patients) and representative number of RA patients across Greece.
Task 3. Identify the Dendritic Cell ( DC) subset that mediates induction of collagen-specific Treg cells. By the use of a novel method that we have developed for inducing antigen-specific Tregs (Verginis et al. 2008, PNAS 105(9):3479-84), will seek to identify the DC subset involved in the induction of collagen-specific Tregs and to address the mechanisms that leads to collagen-specific Treg-mediated suppression of autoimmune arthritis.
Task 4. Comparison of the genetic basis of RA with that of non-RA diseases and exploration of the molecular biology of the variants that exhibit shared causality in RA and RA-like diseases Immunogenetics and functional genetics of shared disease susceptibility genetic loci. In SLE, the center coordinates European efforts for the management of the disease and end-points in clinical trials in lupus. Elucidation of the functional significance of key-gene polymorphisms in RA and RA-like diseases ( SLE) has been a major focus of our group with studies involving co-stimulatory molecules ( PD-1/PD-1L; Arthritis and Rheumatism 2009 and 2010).
