Cervical cells were obtained from Digene cytobrushes, processed within 4 hours, and stained immediately [11 (link)]. The antibodies included: APC-H7-CD3, BV605-CCR6, and APC-CCR5 (all from BD Biosciences, San Jose, CA); BV711-CD8, PE-CCR10, and Alexa-700-human leukocyte antigen (HLA) DR isotope (Biolegend, San Diego, CA); PE-Cy5.5-CD4 (Invitrogen, Carlsbad, CA); and PE-Cy7-cluster of differentiation 38 (CD38) (eBioscience, San Diego, CA). Staining for LIVE-DEAD cells, Pac-blue-CD14, and Pac-blue-CD19 was performed to exclude dead cells, monocytes, and B-cells, respectively (all from Invitrogen). Cells were acquired using the FORTESSA (BD Immunocytometry Systems, San Jose, CA). FlowJo v9.9.3 (FlowJo, LLC, Ashland, OR) was used for the data analysis. The gating strategy is shown in Supplementary Figure 1.

Cervical cells were obtained from Digene cytobrushes, processed within 4 h, and stained immediately to measure T cell frequencies and activation by flow cytometry, as previously described (21 (link)). The gating strategy is shown in Fig. S1 in the supplemental material. The following panel of antibodies was included: APC-H7-CD3, BV605-CCR6, and APC-CCR5 (BD Biosciences); BV711-CD8, PE-CCR10, and Alexa-700-human leukocyte antigen (HLA) DR isotope (BioLegend); PE-Cy5.5-CD4 (Invitrogen); and PE-Cy7-cluster of differentiation 38 (CD38) (eBioscience, Inc.). LIVE-DEAD cell, Pacific-blue-CD14, and Pacific-blue-CD19 (Invitrogen) staining were performed to exclude dead cells, monocytes, and B-cells, respectively. Cells were acquired using an LSRFFortessa (BD Immunocytometry Systems). FlowJo v9.9.3 (FlowJo, LLC) was used for the data analysis.

BSA and streptavidin were from Sigma-Aldrich. PBS was from Gibco. TT was supplied by the Statens Serum Institut. All recombinant influenza HA subtypes were from Sino Biological: H1N1 HA (A/California/04/2009; H1), H2N2 HA (A/Japan/305/1957; H2), H5N1 HA (A/Vietnam/1194/2004; H5), H3N2 HA (A/Perth/16/2009; H3) and H7N9 HA (A/Shanghai/1/2013; H7). H1N1 HA (A/New Caledonia/20/1999; H1 wt), the HA delta stem mutants H1 I45R/T49R and H1 45glyc, and the human monoclonal antibodies CR6261 and CH65 were provided by D. Lingwood. HIV-1 92BR-gp120 was provided by D.R. Burton (Scripps Institute, San Diego, CA). Human CpG ODN 2006 was from InvivoGen. IL-15 and IL-6 were from PeproTech. Antibodies used were as follows: goat anti–human IgG (FcΥ specific; Jackson ImmunoResearch Laboratories, Inc.); anti–human CD27-APC, anti–human CD38-FITC, CD138-PE, CD19-Percp Cy5.5, CD20-APC, CD80-PE-Cy5, HLA-DR-PE-Cy5, and anti–human κ-Ig biotin (eBioscience); anti-human CD86-Bv510, CCR10-PE, CD62L, CXCR4-PE-Cy5, CXCR5-APC, and anti–human λ-Ig biotin (BioLegend); and anti–human CD43-PE and anti–human IgD (Miltenyi Biotec).

Comprehensive Immunophenotyping of T Cell Subsets

Check if the same lab product or an alternative is used in the 5 most similar protocols
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.

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.
