The following antibodies were used: CD3 (VioBlue; Miltenyi Biotech or Pacific blue and PE; BioLegend), CD4 (FITC or APC-Cy7; BioLegend), CD8 (PE-Cy7; BioLegend), CD3/CD19 antibodies (FITC/PE; BD), CD28 (PerCP-Cy5.5; eBioscience), PD-1 (FITC; clone: EH12.2H7; BioLegend), TIM-3 (APC-Cy7; BioLegend), LAG-3 (VioBlue; Miltenyi Biotech), CD45RA (APC-Vio770; Miltenyi Biotec or Brilliant Violet; BioLegend), CCR7 (PerCP-Vio770; Miltenyi Biotec or PerCP; BioLegend), CCR2 (APC; Biolegend), CCR4 (PE; Biolegend), CCR5 (Alexa Influenza 488; Biolegend), CXCR2 (PE-Cy7; Biolegend) and CXCR3 (FITC; Biolegend).
Transduction efficacy was determined on day 6 and day 9 of culture by labeling CAR-T cells with biotin-labeled polyclonal goat anti-mouse F(ab)2 antibody (anti-Fab, Jackson Immunoresearch, West Grove, Pennsylvania) and streptavidin (APC conjugated; BioLegend). CD3+F(ab)2+ cells were defined as CAR-T cells. Isotype labeled cells (Jackson Immunoresearch) and untransduced cells served as negative controls. For further characterization, cells were stained with antibodies mentioned above. Cells were washed and re-suspended in cell staining buffer (BioLegend), incubated for 30 min with the antibodies on ice, washed and measured using MACSQuant FACS cytometer (Miltenyi Biotec). Samples were analyzed by FlowJo software (FlowJo LLC, Ashland, Oregon).

Blood was collected and processed within 4 hours maximum. An ammonium chloride-based lysing reagent (BD Pharm Lyse, BD Biosciences) was used for erythrocyte deletion of 1ml of blood. After washing, cells were suspended in PBS and stained with Aqua Dye (Invitrogen) for cell viability. Cells were washed again, suspended in staining buffer and divided in four tubes. The four different panels assessed contained some common and some specific antibodies. Common antibodies were: CD3-eFluor 605, CD4-Alexa700 (eBioscience, San Diego, CA), CCR7-Horizon PE-CF594, CD38-Brillant Violet 421, HLA-DR-PerCP-Cy5.5 and CD11c-PE-Cy7 (BD Biosciences). Specific for each panel were: 1) CCR2-PE, CCR5-APC-Cy7, CXCR6-APC (R&D Systems Inc.) and CXCR3-FITC (BioLegend); 2) CD49d (α4)-FITC, β7-APC, CCR9-PE (BD Biosciences) and CD29 (β1)–APC-Cy7 (BioLegend); 3) CD103-FITC, CD54-APC, CD49a (α1)-PE and CD29–APC-Cy7 (BioLegend); 4) CD18-APC, CLA-FITC (BD Biosciences) and CCR10-PE (BioLegend). Cells were acquired using a BD LSRFortessa SORP flow cytometer (Flow Cytometry Platform, IGTP) and analyzed with FlowJo 9.3.2 software (TreeStar). Gates were drawn based on fluorescence minus one-controls and isotypes, and CD3+ CD4- phenotype was considered CD8+ T cells.

Quantifying Antigen-Specific T-Cell Frequencies

Analysis of T-cell frequency was accomplished using our previously published approach (26 (link)). Briefly, 40–60 × 106 PBMCs were resuspended in a total of 400–600 µL media, divided into two or three independent tubes of 20 × 106 cells (200 µL) each, incubated with 50 nmol/L dasatinib for 10 min at 37°C, and stained with 20 µg/mL PE-labeled, PE-CF594–labeled, or PE-Cy5–labeled HIP tetramers at room temperature for 120 min (three tetramers per tube for a total of six hybrid peptide tetramers plus an nonimmunogenic control tetramer if adequate cells were available for a third staining tube). Cells were washed, incubated with PE-magnetic beads (Miltenyi Biotec) for 20 min at 4°C, and magnetically enriched; 1% of the cells were retained as a nonenriched sample. Enriched (bound) and nonenriched (precolumn) samples were stained with CD4 V500, CD14 PerCP-Cy5.5, and CD19 PerCP-Cy5.5 (eBioscience) and CD45RA AF700 (BD), CXCR3 FITC, CCR6 BV421, and CCR4 BV605 (BioLegend) for 15 min at 4°C. After washing, cells were labeled with ViaProbe (BD Biosciences) and analyzed on a FACSCanto (BD Biosciences), gating on CD4+CD14CD19ViaProbe cells and plotting tetramer versus CD45RA. Frequencies were calculated as previously described (26 (link)).

Intracellular pSTAT1 and total STAT1 kinetics were determined by FACS analysis. 50 µl whole blood was stimulated according to BD Phosflow™ T Cell Activation Kit Instruction Manual in polystyrene round-bottom tubes (Becton Dickinson Falcon). Blood was stimulated with Imukin® 100ng/ml for 0–180min at 37°C. Erythrocytes were lysed and leucocytes fixed with 1 ml of pre-warmed 1x lyse/fix buffer.

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.
