Recently, PG and SS have been included among the autoinflammatory diseases, which are characterized by recurrent episodes of sterile inflammation, without circulating autoantibodies and autoreactive T cells. However, an autoinflammatory pattern clearly supporting this inclusion has never been demonstrated. We studied 16 patients with PG, six with SS and six controls, evaluating, using a sandwich-based protein antibody array method, the expression profile of inflammatory effector molecules in PG, SS and normal skin. The expressions of interleukin (IL)-1 beta and its receptor I were significantly higher in PG (P = 0\u00b70001 for both) and SS (P = 0\u00b7004\u20130\u00b7040) than in controls. In PG, chemokines such as IL-8 (P = 0\u00b70001), chemokine (C-X-C motif) ligand (CXCL) 1\/2\/3 (P = 0\u00b7002), CXCL 16 (P = 0\u00b7003) and regulated upon activation normal T cell expressed and secreted (RANTES) (P = 0\u00b7005) were over-expressed. In SS, IL-8 (P = 0\u00b7018), CXCL 1\/2\/3 (P = 0\u00b7006) and CXCL 16 (P = 0\u00b7036) but not RANTES were over-expressed, suggesting that chemokine-mediated signals are lower than in PG. Fas\/Fas ligand and CD40\/CD40 ligand systems were over-expressed in PG (P = 0\u00b70001 for Fas, P = 0\u00b7009 for Fas ligand, P = 0\u00b7012 for CD40, P = 0\u00b70001 for CD40 ligand), contributing to tissue damage and inflammation, while their role seems to be less significant in SS. Over-expression of cytokines\/chemokines and molecules amplifying the inflammatory network supports the view that PG and SS are autoinflammatory diseases. The differences in expression profile of inflammatory effectors between these two disorders may explain the stronger local aggressiveness in PG than SS.<\/jats:p>","DOI":"10.1111\/cei.12394","type":"journal-article","created":{"date-parts":[[2014,6,5]],"date-time":"2014-06-05T11:18:44Z","timestamp":1401967124000},"page":"48-56","source":"Crossref","is-referenced-by-count":216,"title":["Expression of cytokines, chemokines and other effector molecules in two prototypic autoinflammatory skin diseases, pyoderma gangrenosum and Sweet's syndrome"],"prefix":"10.1093","volume":"178","author":[{"given":"A V","family":"Marzano","sequence":"first","affiliation":[{"name":"Dipartimento di Fisiopatologia Medico-Chirurgica e dei Trapianti, Universit\u00e0 degli Studi di Milano, Unit\u00e0 Operativa di Dermatologia, IRCCS Fondazione Ca' Granda, Ospedale Maggiore Policlinico, Milano, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"D","family":"Fanoni","sequence":"additional","affiliation":[{"name":"Dipartimento di Fisiopatologia Medico-Chirurgica e dei Trapianti, Universit\u00e0 degli Studi di Milano, Unit\u00e0 Operativa di Dermatologia, IRCCS Fondazione Ca' Granda, Ospedale Maggiore Policlinico, Milano, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"E","family":"Antiga","sequence":"additional","affiliation":[{"name":"Dipartimento di Chirurgia e Medicina Traslazionale, Sezione di Dermatologia, Universit\u00e0 di Firenze, Firenze, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P","family":"Quaglino","sequence":"additional","affiliation":[{"name":"Dipartimento di Scienze Mediche, Divisione di Dermatologia, Universit\u00e0 di Torino, Torino, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M","family":"Caproni","sequence":"additional","affiliation":[{"name":"Dipartimento di Chirurgia e Medicina Traslazionale, Sezione di Dermatologia, Universit\u00e0 di Firenze, Firenze, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C","family":"Crosti","sequence":"additional","affiliation":[{"name":"Dipartimento di Fisiopatologia Medico-Chirurgica e dei Trapianti, Universit\u00e0 degli Studi di Milano, Unit\u00e0 Operativa di Dermatologia, IRCCS Fondazione Ca' Granda, Ospedale Maggiore Policlinico, Milano, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"P L","family":"Meroni","sequence":"additional","affiliation":[{"name":"Dipartimento di Scienze Cliniche e di Comunit\u00e0, Universit\u00e0 degli Studi di Milano, Cattedra di Reumatologia, Istituto G.
