“…Furthermore, the topical administration of an interferon-gene therapy decreased collagen synthesis and upregulated the production of Th1 cytokines [70]. The use of synthetic oligodeoxynucleotides (ODN) containing immunomodulatory CpG motifs in these models has also been shown to block Th2-mediated responses, thus improving skin fibrosis but not emphysema [71,72]. Treatment of Tsk/+ mice with rapamycin, an immunosuppressive molecule that inhibits the mTOR pathway, decreased the production of profibrotic cytokines such as IL-4, IL-6, IL-17 and TGF-and auto-antibodies [73].…”
