Figure Lengend Snippet: Flow-sorted microglia and monocytes cells from Fig 5 were fixed (2% paraformaldehyde) and analyzed by an ImageStream cytometer. Using the IDEAS software package, all doublets or aggregated cells were excluded by gating on single cells. A) P2X4R and CD11b+ were focused and selected. Images of single cells (~300 cells/sample, N=3 per group) of the bright field and fluorescent channel (P2X4R-FITC and CD11b-APC-eFluor780) were acquired, and overlays were generated. Magnification=60x. B) Ratio of median fluorescence intensity (MFI) of P2X4R/CD11b was significantly reduced after 5-BDBD treatment in both microglia and monocytes. Further, a separate comparison of microglia vs. monocytes P2X4R MFI suggests reduced expression of P2X4R in microglia irrespective of treatment. Data are Mean ± SD; *p<0.05, 5-BDBD vs. Vehicle; #p<0.05, microglia vs. monocytes; Student’s t-test.
Article Snippet: Briefly, all the cells isolated from the interphase 70%/30% Percoll gradient were washed and blocked with mouse Fc Block (clone 93, eBioscience, Thermo Fisher, Waltham, MA) before staining for 30 min in dark and cold conditions with primary antibody-conjugated fluorophores: CD45-eF450 (clone 2D1, eBioscience), CD11b-APCeF780 (clone M1/70, eBioscience), Ly6G-AF700 (clone 1A8, eBioscience), Ly6C-PerCP-Cy5.5 (clone HK1.4, BioLegend, San Diego, CA), CX3CR1 APC (Clone SA011F11, BioLegend), and P2X4R-FITC (AFR-024-F, Alomone Labs, Jerusalem, Israel).
