Box plot showing 10th, 25th, 50th, 75th, and 90th centile distribution of the number of peripheral blood cells (PBMNC) expressing mRNA for (A) tumour necrosis factor α (TNFα), (B) interleukin 10 (IL10), and (C) interferon γ (IFNγ) in 11 healthy controls and 16 patients with mild (1), moderate (2), or severe (3) neuropsychiatric lupus erythematosus (NPLE). Patients with moderate and severe disease had more TNFα expressing cells than controls; p<0.001 for both groups.
