Caspase-1 is a well-known activator of IL-18, but caspase-1 knockout mice still have biologically active IL-18. Normal human keratinocyte constitutively produces pro-IL-18, but it is unable to activate it, suggesting the existence of an alternative pathway for IL-18 in the skin. Dermal accumulation of mast cells is commonly observed in AD patients and in experimental mouse models of AD. Connective tissue mast cells contain high amounts of chymase and tryptase in their cytoplasmic granules. In the present study, we demonstrated that activation of IL-18 is a novel function of human mast cell chymase. Human mast cell chymase rapidly cleaves recombinant pro-IL-18 at 56-phenylalanine and produces a biologically active IL-18 fragment that is smaller than any other reported IL-18-derived species. The human mast cell chymase and the novel IL-18-derived active peptide may be novel therapeutic targets in AD- and IL-18-associated diseases<\/jats:p>","DOI":"10.4049\/jimmunol.177.12.8315","type":"journal-article","created":{"date-parts":[[2014,4,18]],"date-time":"2014-04-18T18:56:18Z","timestamp":1397847378000},"page":"8315-8319","source":"Crossref","is-referenced-by-count":124,"title":["Human Mast Cell Chymase Cleaves Pro-IL-18 and Generates a Novel and Biologically Active IL-18 Fragment"],"prefix":"10.1093","volume":"177","author":[{"given":"Youichi","family":"Omoto","sequence":"first","affiliation":[{"name":"Department of Dermatology, Mie University, Graduate School of Medicine , Tsu, Mie ,","place":["Japan"]},{"name":"Core Research of Evolutional Science and Technology, Japan Science and Technology Agency , Kawaguchi ,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kazuya","family":"Tokime","sequence":"additional","affiliation":[{"name":"Department of Dermatology, Mie University, Graduate School of Medicine , Tsu, Mie ,","place":["Japan"]},{"name":"Core Research of Evolutional Science and Technology, Japan Science and Technology Agency , Kawaguchi ,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Keiichi","family":"Yamanaka","sequence":"additional","affiliation":[{"name":"Department of Dermatology, Mie University, Graduate School of Medicine , Tsu, Mie ,","place":["Japan"]},{"name":"Core Research of Evolutional Science and Technology, Japan Science and Technology Agency , Kawaguchi ,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Koji","family":"Habe","sequence":"additional","affiliation":[{"name":"Department of Dermatology, Mie University, Graduate School of Medicine , Tsu, Mie ,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tatsuhiko","family":"Morioka","sequence":"additional","affiliation":[{"name":"Department of Dermatology, Mie University, Graduate School of Medicine , Tsu, Mie ,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ichiro","family":"Kurokawa","sequence":"additional","affiliation":[{"name":"Department of Dermatology, Mie University, Graduate School of Medicine , Tsu, Mie ,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiroko","family":"Tsutsui","sequence":"additional","affiliation":[{"name":"Department of Immunology and Medical Zoology , Nishinomiya ,","place":["Japan"]},{"name":"Core Research of Evolutional Science and Technology, Japan Science and Technology Agency , Kawaguchi ,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kiyofumi","family":"Yamanishi","sequence":"additional","affiliation":[{"name":"Department of Dermatology, Hyogo College of Medicine , Nishinomiya ,","place":["Japan"]},{"name":"Core Research of Evolutional Science and Technology, Japan Science and Technology Agency , Kawaguchi ,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kenji","family":"Nakanishi","sequence":"additional","affiliation":[{"name":"Department of Immunology and Medical Zoology , Nishinomiya ,","place":["Japan"]},{"name":"Core Research of Evolutional Science and Technology, Japan Science and Technology Agency , Kawaguchi ,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hitoshi","family":"Mizutani","sequence":"additional","affiliation":[{"name":"Department of Dermatology, Mie University, Graduate School of Medicine , Tsu, Mie ,","place":["Japan"]},{"name":"Core Research of Evolutional Science and Technology, Japan Science and Technology Agency , Kawaguchi ,","place":["Japan"]}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2006,12,15]]},"reference":[{"key":"2026012810543552300_R1","first-page":"423","volume-title":"Annu.
