Levels of BAFF and APRIL in 115 patients with APAP. Serum levels of BAFF (a) and APRIL (b) were significantly elevated in patients with APAP relative to healthy volunteers (p < 0.0001 and p < 0.05, respectively). Levels of BAFF (c) and APRIL (d) in BALF were significantly elevated in patients with APAP versus disease controls (p < 0.0001 and p < 0.01, respectively). APAP, autoimmune pulmonary alveolar proteinosis; APRIL, a proliferation-inducing ligand; BAFF, B cell-activating factor; BALF, bronchial alveolar lavage fluid
