Neutrophil Evaluation After TB Challenge

The neutrophils from the vaccinated animals were evaluated 30 days after the challenge with M. tuberculosis. The splenocytes were obtained as described above. The cells were incubated for 30 min with APC-conjugated anti-GR1 (BD PharMingen), PercP-conjugated anti-CD14, PE-conjugated anti-CD11c and FITC-conjugated anti-CD11b antibodies (eBioscience). Then, the cells were washed with PBS and fixed with paraformaldehyde using Perm Fix (BD Cytofix). A total of 100,000 events were acquired using BD Biosciences FACSVerseTM and analyzed with the FlowJo 9.0 Software. The neutrophils percentage was determined evaluating singlets that were GR-1+, CD11c-, and CD14-. The total number of neutrophils was obtained multiplying the percentage of neutrophils by the total number of splenocytes from each animal.

Cells from individual diaphragms were recovered following perfusion of blood from tissues, as described previously (22 (link)), and cultured ex vivo for 6 h with 250 ng/ml ionomycin (Sigma-Aldrich), 50 ng/ml PMA (Sigma-Aldrich), and 1 μg/ml brefeldin A (BD Pharmingen). After a 15 min incubation with Fc block (eBioscience) and 10% normal mouse serum, cells were incubated for 15 min with PE-Cy5-conjugated anti-CD4 (eBioscience). Samples were then treated with fixation/permeabilization buffer (eBioscience), and permeabilized cells were incubated for 1 h with PE-conjugated anti-IL-4 (eBioscience) or anti-IL-10 (eBioscience).
For dendritic cell phenotyping, cells from dLNs and diaphragms were incubated FITC-conjugated anti-CD11b, PE-conjugated anti-CD11c and Pacific blue-conjugated anti-MHCII. Data were acquired using a Gallios flow cytometer (Beckman Coulter) and analyzed with FlowJo software (Tree Star).

Phenotypic Analysis of Bone Marrow Dendritic Cells

Bone marrow-derived dendritic cells were stained in FACS buffer (PBS containing 0.1% bovine serum albumin and 5 mM EDTA) using the following monoclonal antibodies in the indicated concentration for cell surface markers (all obtained from eBioscience): PE-conjugated anti-CD86 (2 μg/ml), FITC conjugated anti-CD-40 (5 μg/ml), PE-conjugated anti-CD11c (1 μg/ml), and APC-conjugated MHC-II (0.28 μg/ml). Cells were first incubated with Fc receptor block, 5 μg/ml (eBioscience) for 10 min to block any non-specific binding and subsequent staining steps were performed for 20 min at 4°C, followed by washing with FACS buffer. An isotype-matched control staining was done for each antibody to determine a specific background staining. Cells were acquired using a Cyan-ADP cytometer (Beckman Coulter, Woerden, The Netherlands) and analyzed with FlowJo software (FlowJo LLC, Ashland, OR, USA).

The BMM-derived DCs were generated as describe above and stained with FITC-conjugated anti-CD11c (eBioscience, Thermo Fisher Scientific, San Diego, CA, USA), PE-conjugated anti-CD11c (eBioscience), PE-conjugated anti-MHC class I (eBioscience), PE-Cy5.5-conjugated anti-CD86 (BioLegend, San Diego, CA, USA) or APC- conjugated anti-MHC class II (BioLegend) Ab. To evaluate the percentages of mature DCs in the draining lymph nodes and tumors, the cells expressed with CD11c+ and MHC class Ihi were gated as dendritic cells and then analyzed the co-expression of CD86+ and MHC class IIhi. Flow cytometric analyses were performed as previously described [37 (link),40 (link)].

Isolated lung MNCs were stained with fluorescein isothiocyanate (FITC)-conjugated anti-F4/80 (Clone BM8, eBioscience, San Diego, CA, USA), phycoerythrin (PE)-conjugated anti-CD11c (Clone N418, eBioscience, San Diego, CA, USA) and allophycocyanin/cyanine7 (APC-Cy7)-conjugated anti-CD45 (Clone 104, Biolegend, San Diego, CA, USA). Subsequently, alveolar macrophages (CD45+ F4/80+ CD11c+) were sorted using a FACS Aria II flow cytometer (Becton Dickinson, Franklin Lakes, NJ, USA). The purity of the separated cells was > 95%.

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.
