Ligand competition studies showed that the binding of [125I]-rCNTF was effectively competed by rCNTF and human CNTF, but not by hLIF, mIL-6 or mIL-1B. Three proteins specifically crossed-linked to [125I]-rCNTF, with the molecular weights of 190, 100, and 43 kDa, were immunoprecipitated by anti-rCNTF antibodies. Anti-LIFR or anti-gp130 antibodies immunoprecipitated the 100 and the 190 kDa proteins. CNTF induced the tyrosine phosphorylation of LIFR and gp130, as well as of proteins with the molecular weights of 88/91 and 42 kDa. The phosphorylation of the 88/91 kDa protein(s) was inhibited by pretreating the cells with staurosporine, 12-myristate 13-acetate phorbol (PMA), W7, chlorpromazine, or the intracellular Ca+2 chelator BAPTA/AM. In contrast, CNTF and PMA acted synergistically to induce the phosphorylation of two proteins with the molecular weights of 42 and 44 kDa. At later time points following CNTF treatment, c-fos messenger RNA and protein levels were increased. Collectively, these data indicate that hippocampal astrocytes express high-affinity, biologically functional receptor complexes for CNTF."; prov:wasQuotedFrom pubmed:10082809 . sub:_6 rdfs:label "Selventa" . sub:assertion prov:hadPrimarySource pubmed:10082809; prov:wasDerivedFrom beldoc:, sub:_5 . } sub:pubinfo { this: dct:created "2014-07-03T14:29:46.241+02:00"^^xsd:dateTime; pav:createdBy orcid:0000-0001-6818-334X, orcid:0000-0002-1267-0234 . }
