Spleen and LN cells were harvested from WT or immunized mice. Single cell suspensions were prepared, and RBCs were lysed using Ack lysis buffer (ThermoFisher scientific A1049201). Total CD4+ (Miltenyi 130–049-201) and CD8+ (Miltenyi 130–049-401) T cells were positively purified using Miltenyi kits following established manufacturer protocol followed by FACS sorting. Similarly, antigen presenting cells were isolated using Miltenyi Pan Dendritic Cell (DC) Isolation Kit (Miltenyi 130–100-875). Post CD4+ T cell enrichment, cells were counted and labelled with CellTrace™ Violet Dye (ThermoFisher scientific C34557) according to manufacturer instructions. In vitro proliferation/suppression assays were set up according to previously published protocol47 (link). Briefly, labelled CD4+ T cells were co-cultured either with CD8+ T cells (1:1 ratio, 0.25X106 cells/well) or without CD8+ T cells in the presence of pan DC’s (0.75X106 cells/well). In some of the suppression experiments cells were pre-included with 10ug/ml of anti-Qa-1b neutralizing antibody (6A8.6F10.1A16, BD Biosciences)22 (link),48 (link). Cells were cultured in a total volume of 200 ul in a 96-well round bottom plate. The CD4+ T cells were stimulated with either MOG35–55 or not. On day 7, the cells were washed and stained with surface antibodies and analyzed on LSR II (Becton Dickinson).

Dendritic cells were purified from spleens and mesenteric lymph nodes of WT mice injected with 1 × 106 B16-FLT3L cells using the Pan Dendritic Cell (DC) Isolation Kit (Miltenyi, Germany). Naïve CD4+ T cells were purified following manufacturer’s instructions (Miltenyi, Germany) from the spleen and mesenteric lymph nodes of OT-II mice and labelled with 3 μM VioletTrace (ThermoFisher). Purity was always greater than 98% for both purified DCs and T cells. 1 ×105 DCs were incubated with peptide (50 nM) for 1 h before adding 1 *105 T cells. Proliferation was assessed using dilution of VioletTrace and analyzed by flow cytometry after 3.5 days of coculture.

We have previously reported that 2.0-mm circular incisions of the corneal epithelium induce the generation of CS cells that express the CD11c surface marker.20 (link) Corneas of BALB/c mice were trephined as described previously, and CD11c+ spleen cells were isolated 4 days later using a Miltenyl Biotec (Santa Barbara, CA) pan dendritic cell (DC) isolation kit.20 (link) The CD11c+ cells from trephined mice and untreated mice were used for detecting regulatory cell activity in vitro.20 (link)

Isolation and Characterization of Adipocyte and Adipose Immune Cell Fractions

Adipocyte and adipose SVF, ART and ATM fractions were isolated from epididymal VAT10 (link). Briefly, adipocytes were incubated with biotinylated CD45 antibody (eBiosciences, 13-0451-85, 1:400 dilution) to remove leukocyte contamination and the purified CD45 negative adipocytes were used for the gene expression analysis and cell co-culture. ATMs and ARTs were isolated from SVF with biotinylated F4/80 (eBiosciences, 13-4801-85, 1:200 dilution) and CD3e (eBiosciences, 13-0031-85, 1:100 dilution) antibodies, respectively. BMDMs and PMs were generated39 (link). DCs were isolated from spleens of WT and aMHCII−/− mice by using Miltenyi Pan Dendritic Cell Isolation Kit. Cell and tissue RNA samples were isolated and analysed, as previously described10 (link).

10–14 week old C57BL/6 males served as gLN donors, and biological triplicates or quadruplicates were collected. Cells were sorted using a FACS Aria cell sorter flow cytometer (Becton Dickinson). MLN dendritic cells were pre-enriched using a Pan Dendritic Cell Isolation Kit (130–100-875, Miltenyi Biotec) and LS MACS Separation Columns (Miltenyi Biotec). Dendritic cells were sorted as AquaCD45+Lin(CD3B220NK1.1CD19) CD11chi, and the subpopulations further as MHCIIhiCD103+CD11b and MHCIIhiCD103+CD11b+. Stromal cells were not pre-enriched and sorted as AquaCD45TER119CD24TCRβB220CD11c cells, and the subpopulations further as podoplanin+CD31 (FRCs) and podoplanin+CD31+(LECs). Three hundred cells were sorted directly into 25 μl TCL buffer (Qiagen, 1031576) supplemented with 1% β-mercaptoethanol at single cell precision. Samples were kept at room temperature for 5 min, spun down and kept at −80 °C until further processing.

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.
