Inflammation of the lacrimal gland induces tear abnormalities that contribute to the inflammation of the ocular surface, which includes ocular mucosa. Thrombospondin-1 (TSP-1) plays a critical regulatory role in the ocular mucosa and as such TSP-1\u2013\/\u2013 mice develop spontaneously chronic ocular surface inflammation associated with Sj\u00f6gren's syndrome. The autoimmune pathology is also accompanied by a peripheral imbalance in regulatory (Treg) and inflammatory Th17 effectors. In this study, we demonstrate an in-vitro effect of a CD47-binding TSP-derived peptide in the induction of transforming growth factor (TGF)-\u03b21-secreting forkhead box protein 2 (Foxp3+) Tregs from activated CD4+CD25\u2013 T cells and the inhibition of pathogenic T helper type 17 (Th17)-promoting interleukin (IL)-23 derived from antigen-presenting cells. The in-vivo administration of this peptide promotes Foxp3+ Treg induction and inhibition of Th17 development. Consistent with these results, topical administration of CD47-binding TSP peptide, both before and after the onset of the disease, attenuates clinical symptoms of SS-associated dry eye in TSP-1\u2013\/\u2013 mice. Augmented expression of Foxp3 detected in the draining lymph nodes of TSP peptide -treated mice compared to those treated with control peptide suggests the ability of TSP peptide to restore peripheral immune imbalance. Thus, our results suggest that TSP-derived peptide attenuates Sj\u00f6gren's syndrome-associated dry eye and autoimmune inflammation by preventing Th17 development while promoting the induction of Tregs. Collectively, our data identify TSP-derived peptide as a novel therapeutic option to treat autoimmune diseases.<\/jats:p>","DOI":"10.1111\/cei.12919","type":"journal-article","created":{"date-parts":[[2016,12,29]],"date-time":"2016-12-29T23:08:53Z","timestamp":1483052933000},"page":"86-95","source":"Crossref","is-referenced-by-count":27,"title":["Thrombospondin-derived peptide attenuates Sj\u00f6gren's syndrome-associated ocular surface inflammation in mice"],"prefix":"10.1093","volume":"188","author":[{"given":"L","family":"Contreras Ruiz","sequence":"first","affiliation":[{"name":"Department of Ophthalmology, Boston University School of Medicine, Boston, MA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"F A","family":"Mir","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Boston University School of Medicine, Boston, MA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"B","family":"Turpie","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Boston University School of Medicine, Boston, MA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S","family":"Masli","sequence":"additional","affiliation":[{"name":"Department of Ophthalmology, Boston University School of Medicine, Boston, MA, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2017,1,31]]},"reference":[{"key":"2021120808031424700_cei12919-bib-0001","first-page":"1240","article-title":"Th1- and Th2-type cytokines in chronic ocular allergy.
