In living patients, the diagnosis, based on suggestive clinical features and EEG abnormalities, can be aided by the detection of altered levels of isoforms of the 14\u20103\u20103 protein in the cerebrospinal fluid (CSF). However, the validity of this test has been recently challenged and the search for other, more reliable biomarkers for CJD remains highly desirable. The present study describes the identification of a new potential surrogate marker in the CSF of CJD\u2010affected patients. A preliminary study employing surface\u2010enhanced laser desorption\/ionization\u2010time of flight (SELDI\u2010TOF) technology highlighted a protein at 13.4\u00a0kDa in a small group (\n                    <jats:italic>n<\/jats:italic>\n                    = 8) of CJD\u2010affected patients. Further analysis aimed at identifying this protein using cationic exchange chromatography, sodium dodecyl sulfate\u2010polyacrylamide gel electrophoresis (SDS\u2010PAGE), and liquid chromatography\u2010tandem mass spectrometry (LC\u2010MS\/MS) revealed it to be cystatin C. Additional immunoblot assays confirmed that the level of cystatin C was significantly increased (\n                    <jats:italic>p<\/jats:italic>\n                    \u2264 0.05) in all tested samples (\n                    <jats:italic>n<\/jats:italic>\n                    = 8). We conclude that the analysis of cystatin C levels in CSF could be useful as a\n                    <jats:italic>pre\u2010mortem<\/jats:italic>\n                    indicator of the disease.\n                  <\/jats:p>","DOI":"10.1002\/pmic.200300799","type":"journal-article","created":{"date-parts":[[2004,6,21]],"date-time":"2004-06-21T05:00:42Z","timestamp":1087794042000},"page":"2229-2233","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":86,"title":["Cystatin C as a potential cerebrospinal fluid marker for the diagnosis of Creutzfeldt\u2010Jakob disease"],"prefix":"10.1002","volume":"4","author":[{"given":"Jean\u2010Charles","family":"Sanchez","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Elisabeth","family":"Guillaume","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pierre","family":"Lescuyer","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Laure","family":"Allard","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Odile","family":"Carrette","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alex","family":"Scherl","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jennifer","family":"Burgess","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Garry L.","family":"Corthals","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Pierre R.","family":"Burkhard","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Denis F.","family":"Hochstrasser","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2004,7,20]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1073\/pnas.95.23.13363"},{"key":"e_1_2_1_3_2","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.55.4.514"},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.58.3.509"},{"key":"e_1_2_1_5_2","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.55.9.1396"},{"key":"e_1_2_1_6_2","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.56.11.1528"},{"key":"e_1_2_1_7_2","doi-asserted-by":"publisher","DOI":"10.1042\/BST0300382"},{"key":"e_1_2_1_8_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0304-3940(02)00172-6"},{"key":"e_1_2_1_9_2","doi-asserted-by":"publisher","DOI":"10.1002\/pmic.200300478"},{"key":"e_1_2_1_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/0003-2697(87)90587-2"},{"key":"e_1_2_1_11_2","doi-asserted-by":"publisher","DOI":"10.1021\/ac990448m"},{"key":"e_1_2_1_12_2","doi-asserted-by":"publisher","DOI":"10.1016\/0305-0491(94)00229-N"},{"key":"e_1_2_1_13_2","doi-asserted-by":"publisher","DOI":"10.1046\/j.1440-1789.2000.00268.x"},{"key":"e_1_2_1_14_2","doi-asserted-by":"publisher","DOI":"10.1002\/pmic.200300470"}],"container-title":["PROTEOMICS"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fpmic.200300799","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/analyticalsciencejournals.onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/pmic.200300799","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,10,21]],"date-time":"2025-10-21T17:27:59Z","timestamp":1761067679000},"score":1,"resource":{"primary":{"URL":"https:\/\/analyticalsciencejournals.onlinelibrary.wiley.com\/doi\/10.1002\/pmic.200300799"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2004,7,20]]},"references-count":13,"journal-issue":{"issue":"8","published-print":{"date-parts":[[2004,8]]}},"alternative-id":["10.1002\/pmic.200300799"],"URL":"https:\/\/doi.org\/10.1002\/pmic.200300799","archive":["Portico"],"relation":{},"ISSN":["1615-9853","1615-9861"],"issn-type":[{"value":"1615-9853","type":"print"},{"value":"1615-9861","type":"electronic"}],"subject":[],"published":{"date-parts":[[2004,7,20]]},"assertion":[{"value":"2003-12-15","order":0,"name":"received","label":"Received","group":{"name":"publication_history","label":"Publication History"}},{"value":"2004-07-20","order":3,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
