The harvested BMDC (2 × 106 /well) were stimulated in triplicate with LPS (1 μg/mL), alone or together with ALX at 2 or 10 μM in 6-well plates for 2 days. The cells were stained with PE-anti-CD11c, Percp-cy5.5-anti-MHC-II, FITC-anti-CD80 or FITC-anti-CD86, or isotype controls (eBioscience), washed, and analyzed by flow cytometry.
On days 24–26 post-immunization, six mice from each group were sacrificed, and their splenic mononuclear cells were isolated. The cells were stimulated with Cell Stimulation Cocktail (PMA + Ionomycin, eBioscience) for 5 h. The cells were stained with FITC-anti-CD4 (eBioscience), fixed, and permeabilized. After being washed, the cells were stained intracellularly with PE-anti-IFN-γ or PE-anti-IL-17 (eBioscience). The frequency of Th1 (CD4+IFN-γ+) and Th17 (CD4+Th17+) cells in total CD4+ T cells was determined by flow cytometry.
On days 15 post-immunization (the early stage of EAE), splenic mononuclear cells were isolated from the vehicle or ALX-treated EAE mice. The cells were stimulated with 20 μg/ml of MOG35-55 for 48 h and stained with PE-anti-CD11c, Percp-cy5.5-anti-MHC-II, FITC-anti-CD80 or FITC-anti-CD86, or isotype controls (eBioscience), and their expression levels were characterized by flow cytometry.

To assess the effects of BC on immune cells, D1DCs (a murine dendritic cell line) [22 (link)] were cultured with increasing amounts of BC extracts (up to 20 mg/mL). After 48 h, the D1DCs were detached using PBS/EDTA, washed with FACS buffer (PBS with 0.5% BSA and 0.02% sodium azide) and stained at 4 °C for 30 min with the following antibodies: anti-CD40-APC (Biolegend, San Diego, CA, USA, clone 3/23, #12-4612), anti-CD86-FITC (eBioscience, San Diego, CA, USA) clone GL1, #11-0862-85,) and anti-MHC II-PE (eBioscience, San Diego, CA, USA) clone M5/114.15.2, #12-5321-82). 7-AAD (Invitrogen, Waltham, MA, USA, #A1310) was included to stain the dead cells. Thereafter, the cells were washed with FACS buffer to remove unbound antibodies and resuspended in 100 μL FACS buffer. FACS analysis was performed on an LSR-II cytometer (BD Biosciences, Franklin Lakes, NJ, USA). The data were analyzed with FlowJo V10.

In order to evaluate the effect of CaF2: Ce, Gd, Nd NPs on immune cells, we used flow cytometry to assess the expression of DC maturation/activation markers. Briefly, murine D1 DCs and 125 µg/mL CaF2: Ce, Gd, Nd NPs were co-cultured in a 96-well plate for 24 h in a 37 °C incubator. PBS/EDTA (Sigma-Aldrich, St. Louis, MO, USA) was used to detach the cells, which were then washed with FACS buffer and stained with anti-CD40-APC (Biolegend, San Diego, CA, USA) and anti-CD86-FITC (eBioscience, San Diego, CA, USA) antibodies. The cells were washed and resuspended in 100 μL FACS buffer after 30 min. A LSR-II cytometer (BD Biosciences, Franklin Lakes, NJ, USA) was used to measure the samples, and FlowJo (version 10) was utilized to analyze the data.

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.
