{"title":"The molecular basis for therapeutic concepts utilizing CD14.","authors":"F Stelter,&nbsp;M Bernheiden,&nbsp;R Menzel,&nbsp;S Witt,&nbsp;R S Jack,&nbsp;U Grunwald,&nbsp;X Fan,&nbsp;C Schütt","doi":"","DOIUrl":"","url":null,"abstract":"<p><p>The CD14 molecule is a key receptor on myeloid lineage cells involved in the recognition of lipopolysaccharide (LPS) and Gram-negative bacteria. The application of its soluble form, sCD14, has been shown to protect mice from lethality in LPS-induced shock. Therefore the protein or its derivatives may be considered as a possible therapeutic alternative for the treatment of patients suffering from Gram-negative septic shock. In this study we performed an alanine scan of amino acids 1 to 152 of human CD14. Twenty-three substitution mutants were generated and stably transfected into CHO-cells. In each mutant five amino acids were substituted by alanine. We analyzed (a) whether mutant proteins expressed on the surface of transfectants were recognized by a panel of anti-CD14 monoclonal antibodies (mAb's), (b) the ability of mCD14-mutants to bind LPS and E. coli in a serum- or LBP-dependent manner, and (c) the capacity of soluble mutants to mediate the LPS-induced IL 6 release of U 373 astrocytoma cells. Twenty-one CD14-mutants were expressed on the surface of transfectants and 18 were present as soluble forms in the culture supernatants. We demonstrated that only CD14(39-41,43-44)A completely lacked the ability to bind LPS and E. coli. In addition, a combined mutant CD14(9-13/57,59,61-63)A had very limited capacity to interact with LPS indicating that the LPS-binding site of human CD14 is a conformational epitope. Analysis of LPS-induced activation of CD14-negative U 373 cells revealed that the regions 9-13 and 91-101 are most important for sCD14-mediated signalling.</p>","PeriodicalId":20686,"journal":{"name":"Progress in clinical and biological research","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"1998-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20497118","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
