Inflammatory cytokines in thymus induce the formation of germinal centres (GC). MG thymic inflammatory cytokines are predominantly secreted by stromal cells. Our previous studies revealed that the expression level of the Fra1 protein, which is a Fos member of the activator protein 1 transcription factors (AP\u20101), was higher in the MG thymus compared with that of the normal thymus. Based on that, we demonstrated that Fra1 was mainly expressed in medulla thymic epithelial cells (mTECs) and that the rate of Fra1 positive mTECs in the MG thymus was higher than normal. In vitro, we found that the expression of CCL\u20105, CCL\u201019 and CCL\u201021 could be regulated by Fra1 in mTEC and that IL\u20101\u03b2, IL\u20106, IL\u20108 and ICAM1 were downregulated in the Fra1 overexpression group and upregulated in the Fra1 knock\u2010down group. Meanwhile, we detected that the expression levels of suppressor of cytokine signalling 3 (SOCS3) were significantly upregulated along with the overexpression of Fra1. Hence, we considered that the overexpression of Fra1 disrupted inflammatory cytokine secretion by mTEC in the MG thymus and that STAT3 and SOCS3 were strongly involved in this process.<\/jats:p>","DOI":"10.1111\/sji.12676","type":"journal-article","created":{"date-parts":[[2018,5,28]],"date-time":"2018-05-28T21:30:20Z","timestamp":1527543020000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":13,"title":["The
