We have investigated the expression and bioregulation of particular KLKs in the human neutrophil and, in addition, examined whether stimulation by a kinin B\n                    <jats:sub>1<\/jats:sub>\n                    receptor (B1R) agonist or fMet-Leu-Phe (fMLP) induces their secretion. Western blot analysis of neutrophil homogenates indicated that the MM of the KLKs ranged from 27 to 50\u2009kDa. RT-PCR showed that blood neutrophils expressed only KLK1, KLK4, KLK10, KLK13, KLK14 and KLK15 mRNAs, whereas the non-differentiated HL-60 cells expressed most of them, with exception of KLK3 and KLK7. Nevertheless, mRNAs for KLK2, KLK5, KLK6 and KLK9 that were previously undetectable appeared after challenging with a mixture of cytokines. Both kinin B\n                    <jats:sub>1<\/jats:sub>\n                    R agonist and fMLP induced secretion of KLK1, KLK6, KLK10, KLK13 and KLK14 into the culture medium in similar amounts, whereas the B\n                    <jats:sub>1<\/jats:sub>\n                    R agonist caused the release of lower amounts of KLK2, KLK4 and KLK5. When secreted, the differing proteolytic activity of KLKs provides the human neutrophil with a multifunctional enzymatic capacity supporting a new dimension for its role in human disorders of diverse etiology.\n                  <\/jats:p>","DOI":"10.1177\/1753425914566083","type":"journal-article","created":{"date-parts":[[2015,1,7]],"date-time":"2015-01-07T05:23:30Z","timestamp":1420608210000},"page":"575-586","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":35,"title":["Expression and bioregulation of the kallikrein-related peptidases family in the human neutrophil"],"prefix":"10.1177","volume":"21","author":[{"given":"Alejandro J","family":"Lizama","sequence":"first","affiliation":[{"name":"Laboratorio de Patologia Celular, Instituto de Anatomia, Histologia y Patologia, Universidad Austral de Chile, Valdivia, Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yessica","family":"Andrade","sequence":"additional","affiliation":[{"name":"Laboratorio de Patologia Celular, Instituto de Anatomia, Histologia y Patologia, Universidad Austral de Chile, Valdivia, Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Patricio","family":"Colivoro","sequence":"additional","affiliation":[{"name":"Laboratorio de Patologia Celular, Instituto de Anatomia, Histologia y Patologia, Universidad Austral de Chile, Valdivia, Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jose","family":"Sarmiento","sequence":"additional","affiliation":[{"name":"Instituto de Fisiologia, Universidad Austral de Chile, Valdivia, Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carola E","family":"Matus","sequence":"additional","affiliation":[{"name":"Laboratorio de Patologia Celular, Instituto de Anatomia, Histologia y Patologia, Universidad Austral de Chile, Valdivia, Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carlos B","family":"Gonzalez","sequence":"additional","affiliation":[{"name":"Instituto de Fisiologia, Universidad Austral de Chile, Valdivia, Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kanti D","family":"Bhoola","sequence":"additional","affiliation":[{"name":"Laboratorio de Patologia Celular, Instituto de Anatomia, Histologia y Patologia, Universidad Austral de Chile, Valdivia, Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pamela","family":"Ehrenfeld","sequence":"additional","affiliation":[{"name":"Laboratorio de Patologia Celular, Instituto de Anatomia, Histologia y Patologia, Universidad Austral de Chile, Valdivia, Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carlos D","family":"Figueroa","sequence":"additional","affiliation":[{"name":"Laboratorio de Patologia Celular, Instituto de Anatomia, Histologia y Patologia, Universidad Austral de Chile, Valdivia, Chile"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2015,1,6]]},"reference":[{"key":"bibr1-1753425914566083","doi-asserted-by":"publisher","DOI":"10.1084\/jem.20122220"},{"key":"bibr2-1753425914566083","doi-asserted-by":"publisher","DOI":"10.1006\/bbrc.2000.3448"},{"key":"bibr3-1753425914566083","doi-asserted-by":"publisher","DOI":"10.1074\/jbc.M004525200"},{"key":"bibr4-1753425914566083","doi-asserted-by":"publisher","DOI":"10.1016\/S0163-7258(00)00080-2"},{"key":"bibr5-1753425914566083","doi-asserted-by":"publisher","DOI":"10.1080\/10408360490471931"},{"key":"bibr6-1753425914566083","doi-asserted-by":"crossref","unstructured":"Emami N and Diamandis EP.
