IL17A and pneumonitis: 3,3′-diselenodipropionic acid (DSePA) had maximum absorption in the lung, suppressed NF-kB/IL-17/G-CSF/neutrophil axis and significantly reduced infiltration of neutrophils and levels of IL1-β, ICAM-1, E-selectin, IL-17 and TGF-β in the bronchoalveolar fluid, prevented pneumonitis and increased survival of irradiated mice without affecting radiation sensitivity of tumors [212].
