Our selection includes cytokines previously associated with the lung response to radiation in both mice and humans such as Il6 and Tnfα [15,16,37,38]) as well as pulmonary fibrosis-promoting Il1β, Il13 and Il17 [39,40]) and anti-fibrotic mediators Il10 and Ifnγ [41]. The gene discussed is IL13; the disease is pulmonary fibrosis.
