While CXCL1, CXCL2, and CXCL5 gene transcripts were shown to be elevated in a mouse model of severe asthma, treatment with Ruxolitinib, an anti-inflammatory drug and powerful inhibitor of janus kinase 1/2 (JAK1/2), caused the upward spiraling to be reversed [43]. The gene discussed is JAK1; the disease is asthma.
