Other identified pathways included the pulmonary fibrosis idiopathic signaling pathway in CD4+ T-cells (p = 9.33E − 06), the multiple sclerosis signaling pathway and the IL-15 production pathway in CD8+ T-cells (p = 9.55E − 07 and p = 3.63E − 05, respectively). The gene discussed is CD4; the disease is multiple sclerosis.
