Human peripheral blood cells: autoimmune diseases vs. healthy individuals

Gene expression profiling of peripheral blood cells from patients with rheumatoid arthritis (RA)/ systemic lupus erythematosus (SLE)/ polyarticular type juvenile idiopathic arthritis (polyJIA)/ systemic-onset JIA (sJIA) vs healthy children (HC) and healthy individual (HI). Peripheral blood was obtained from patients with RA (n=112), SLE (n=22), polyJIA (n=6), sJIA (n=51), HC (n=8), and HI (n=45). Blood samples from 8 HC and 45 HI are used as control.
