Cell stimulating antibodies to CD3 (clone OKT-3), CD28 (clone AF-342-PB) and CD46 (clone 344519) were all purchased from R&D Systems. Neutralizing antibodies to IL-4 (clone 8D4-8) and IL-10 (clone JES3-19F1) were both from BD Pharmingen. Antibodies used in flow cytometric analysis were FITC-labeled anti-CD46 (clone MEM-258), BV421-labeled anti-CD122 (clone TU27), PE-labeled anti-CD132 (clone AG184) from BioLegend, and FITC-labeled anti-CD19 (clone 4G7-2E3) and APC-labeled anti-CD138 (clone 359103), both from R&D Systems, while the APC-labelled anti-CD25 (clone M-A251) was purchased from BD Pharmingen. Recombinant human IL-2 and IL-10 were purchased from Pepro-Tech and soluble CD46 was prepared as previously described.10 The MMP-9 inhibitor was purchased from Calbiochem (CAS 1177749-58-4) and used at the concentrations indicated in the respective experiments.

Fluorochrome-labeled monoclonal antibodies used for the phenotypic and intracellular staining assay included CD3 (clone UCHT1), CD4 (clone RPA-T4), CD8 (clone SK1), CCR7 (clone 3D12), CXCR4 (clone12G5), CCR5 (clone 2D7), CD8 (clone RPA-T8), IFNγ (clone B27), TNFα (clone MAb11), MIP-1ß (clone D21-1351) from Becton-Dickinson Pharmingen (San Diego, CA); CD45RA (2H4), CD4 (clone T4D11) from Beckman Coulter (Fullerton, CA); CD38 (clone HB7), CD107a (clone H4A3), and IL10 (clone JES3-19F1) from BD Biosciences (San Jose, CA); HLADR (clone TU36), aqua amine reactive dye from Invitrogen (Carlsbad, CA); CD66b (G10F5) Biolegend (San Diego, CA); and IL17 (clone eBio64CAP17), IL2 (clone MQ1-17H12), from eBioscience (San Diego, CA). Optimum antibody titers were determined empirically for each antibody based on preliminary titration experiments using serial dilutions, which included the manufacturers’ recommended amounts. Flow cytometry data were acquired on an LSRII (BD Immunocytometry Systems, San Jose, CA) equipped with 405, 488, and 643 nm lasers and utilizing FACSDIVA software (BDIS). Analysis of cytometry data was done with FlowJo software (TreeStar, Ashland, OR). Results were recorded as the percentage of CD4+ or CD8+ T-cells expressing a given surface marker or combination of markers.

Culture supernatants from amplified T cell libraries assay were assayed for the presence of cytokines by ELISA. ELISA measurement of cytokines was performed with purified coating and biotinylated detection antibodies, as follows: IFN-γ, clone 2G1 and human IFN-γ mAb biotin-labeled (Thermo Scientific, Walthman, MA); IL-10, clone JES3-19F1 and biotin anti-human and viral IL-10 (BD Biosciences). Production of IL-17 and GM-CSF were measured with a DuoSet ELISA Development kit (R&D Systems, Minneapolis, MN). The absorbance was measured and analyzed on a microplate read (Bio-Rad, Hercules, CA).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
