On an individual marker level, the largest differences between healthy subjects and patients with lupus nephritis were a decrease in CD18a (median signal intensity 0.165 (LN) versus 0.859 (HD)) and an increase in LAMP1 in patients with lupus nephritis compared with healthy subjects (median signal intensity 0.170 (lupus nephritis) versus 0 (healthy subjects)) (Figures 1E,F). The gene discussed is LAMP1; the disease is lupus nephritis.
