    Description and characterization of the chimeric human <t>FasL-derived</t> constructs Panel A: Schematic representation of soluble FasL (sFasL), Flag-tagged sFasL (sfFasL), polymeric Flag-tagged soluble FasL (pfFasL), polymeric TCR γ4 and δ5 Flag-tagged soluble FasL generating the TCR-pfFasL upon cotransfection, and beta2-microglobulin-fused HLA-A*02: 01 Flag-tagged soluble FasL (HLA-pfFasL). The f and p symbols represent the flag epitope and the LIF receptor-derived domain triggering the polymerisation of the FasL oligomers, respectively. Panel B: direct immunoblot of the supernatants from COS cells transfected with the empty vector (control) or the FasL constructs sFasL, sfFasL and pfFasL. Panel C: immunoprecipitation of the TCR-pfFasL chimera from transfected HEK cells, using an irrelevant IgG1 antibody, the anti-Flag (clone M2), the anti-FasL (clone 10F2), the anti-TCRγδ (clone IMU-510) or the anti-TCRδ5 (clone 12C7) antibodies. Panel D: immunoprecipitation of the HLA-pfFasL chimera from the supernatant of COS cells, with anti-Flag, anti-FasL or anti-β2microglobulin antibodies. As controls, the same experiment was performed with irrelevant IgG1 and IgG2 antibodies. Panel E: cytotoxic effect of the FasL chimeras. The indicated chimeras, as supernatants from transfected cells and quantitated using the <t>ELISA</t> for FasL, were incubated at the indicated concentrations with Jurkat cells. After 18 h, the MTT cell viability assay was performed. The anti-Flag M2 antibody at 0.5 µg/ml was added to sfFasL to render it cytotoxic.

    Analysis of <t>GRP78–HTJ1</t> and OxPL–GRP78 interactions. (A) GRP78 and HTJ1 expression in HPAEC and human lung microvascular endothelial cells was detected by Western Blot. (B, C) GRP78 interactions were analyzed in coimmunoprecipitation assays using lysates from control or DMPC- (10 μg/ml, 15 min) or OxPAPC-stimulated (10 μg/ml) cells with antibody to GRP78 (B, top), HTJ1 (B, bottom), or EO6 antibody recognizing OxPL (C). (D) Human recombinant GRP78 was incubated with OxPAPC, OxPAPS, or their oxidation-resistant analogues DMPC or DMPS. Left, native gel electrophoresis, followed by Western blot with anti-GRP78 antibody. Shift in electrophoretic mobility of GRP78 incubated with OxPAPS, but not DMPS, indicates formation of GRP78–OxPAPS complex. Right, SDS–PAGE, followed by Western blot with EO6 antibody and reprobing with anti-GRP78 antibody. Positive EO6 immunoreactivity of GRP78 preincubated with OxPAPC indicates formation of GRP78–OxPAPC complex. (E) <t>ELISA</t> plates coated with OxPAPS or DMPS or control uncoated plates incubated with PBS incubated with human recombinant GRP78 (left) or HPAEC lysates (middle and right).

For the sfFasL construct, the filled squares and the empty squares depict the cytotoxicity of sfFasL in the presence and absence of the cross-linking anti-Flag antibody at 0.5 µg/ml), respectively. Cytotoxicity was estimated by a measure of the remaining viable cells using the MTT assay. Are presented the mean +/- sd of four independent transfection experiments. * 0.01≤p≤0.05; ** p≤0.01.

    Analysis of GRP78–HTJ1 and OxPL–GRP78 interactions. (A) GRP78 and HTJ1 expression in HPAEC and human lung microvascular endothelial cells was detected by Western Blot. (B, C) GRP78 interactions were analyzed in coimmunoprecipitation assays using lysates from control or DMPC- (10 μg/ml, 15 min) or OxPAPC-stimulated (10 μg/ml) cells with antibody to GRP78 (B, top), HTJ1 (B, bottom), or EO6 antibody recognizing OxPL (C). (D) Human recombinant GRP78 was incubated with OxPAPC, OxPAPS, or their oxidation-resistant analogues DMPC or DMPS. Left, native gel electrophoresis, followed by Western blot with anti-GRP78 antibody. Shift in electrophoretic mobility of GRP78 incubated with OxPAPS, but not DMPS, indicates formation of GRP78–OxPAPS complex. Right, SDS–PAGE, followed by Western blot with EO6 antibody and reprobing with anti-GRP78 antibody. Positive EO6 immunoreactivity of GRP78 preincubated with OxPAPC indicates formation of GRP78–OxPAPC complex. (E) ELISA plates coated with OxPAPS or DMPS or control uncoated plates incubated with PBS incubated with human recombinant GRP78 (left) or HPAEC lysates (middle and right). The bound GRP78 was detected using anti-GRP78 antibody. * p
