Isolation of Inflammatory Leukocytes from CNS

Inflammatory leukocytes infiltrating into the CNS were isolated using an established protocol (3,4). In short, CNS tissue was minced and leukocytes were isolated using a two‐step Percoll gradient (90% and 63%). The isolated cells were collected and then washed prior to staining. Cells were incubated in an anti‐CD16/32 Fc Block (BD Biosciences, San Jose, CA) at a dilution of 1:200. Cells were stained with fluorescently tagged rat anti‐mouse IgG for the following cell surface antibodies, Ly6G FITC (1A8), CD11b PE (M1/70), CD45 BV510 (30‐F11), CD8 PE‐Cy7 (53–6.7), (BD Biosciences), Ly6C APC (HK1.4), CD4 BV785 (RM4‐5), F4/80 FITC (BM8), I‐A/I‐E APC (M5/114.15.2), CD11c FITC (N418) (Biolegend, San Diego, CA), and CD4 FITC (RM4‐5) or Armenian hamster anti‐mouse IgG for CD80 PerCP‐Cy5.5 (16‐10A1) (BD Biosciences). A full description of gating strategies for flow cytometric staining and intracellular cytokine staining is provided in the Supporting Information Figs. S1–S4.

Comprehensive Lymph Node Immune Cell Analysis

Check if the same lab product or an alternative is used in the 5 most similar protocols
Single cell suspensions from pooled inguinal lymph nodes of each mouse were treated with erythrocyte lysis buffer (20 mM Tris/HCl, 155 mM NH4Cl, pH = 7.2) and washed with 5% FBS in PBS. Cell counts were determined using a Neubauer hemocytometer. Cells were stained with fluorescently-labeled mAbs as previously described (27 (link)). The following antibodies were used: B220-APCCy7 (RA3-6B2; BD Biosciences, San Jose, CA), CD4-FITC (RM4-5; BD Biosciences), CD95-Biotin (15A7; eBioscience), Streptavadin-PE (BioLegend, San Diego, CA), GL7-EF450 (GL-7; eBioscience), PD-1-PECy7 (RMP1-30; BioLegend), CXCR5-APC (L138D7; BioLegend), FcεRI-FITC (MAR-1; BioLegend), CD200R-PE (OX-108; BioLegend), cKit-APC (2B8; eBioscience), CD45-APC (104; eBioscience) CD49b-PerCPCy5.5 (DX5; BioLegend), phosphorylated p38-PECy7 (pT180/pY182; BD Biosciences), and CD41-BV421 (WMReg30; BD Biosciences). Cell viability was determined using live/dead Aqua (Invitrogen, Carlsbad, CA) and doublets were excluded based on forward scatter and pulse width. Samples were acquired on a CyAn ADP LX (Beckman Coulter, Brea, CA) or CytoFLEX (Beckman Coulter) and analyzed using FlowJo software version 10.1r7 (Treestar, Ashland, OR). Gates were determined using fluorescence-minus-one staining controls.

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.
