Several proteins were identified with higher abundance in BAL of sarcoidosis patients, including cadherin 5 (CDH5), transferrin (TF), C-C motif chemokine 24 (CCL24), interleukin 15 (IL15) apolipoprotein A (LPA) and mitochondrial superoxide dismutase (SOD2). This evidence concerns the gene CCL24 and sarcoidosis.
