Figure Lengend Snippet: In vitro biological effects of PFP-OLNDs in BV2 microglia. BV2 microglia were pre-incubated with different concentrations of PFP-OLNDs for 3 hours and then exposed to LPS for 24 hours. (A, B) ROS formation detected by flow cytometry. (C) Representative histograms of CD45, MHC class II and CD86 expression on microglia of different groups. Unstained control (Con) is indicated in the shaded histogram. Blank represents the PBS-treated group. (D) Surface expression (MFI) of CD45, MHC class II and CD86 are shown. (E, F) Western blotting of IL-1β, IL-6, and iNOS. (G) ELISA of IL-1β, IL-6, and TNFα from BV2 cellular supernatant. Data are expressed as mean ± SEM ( n = 3). ** P < 0.01, *** P < 0.001, vs. LPS (one-way analysis of variance followed by Bonferroni post hoc test). DCFH-DA: 2′,7′-Dichlorodihydrofluorescein diacetate; ELISA: enzyme-linked immunosorbent assay; IL-1β: interleukin 1 beta; IL-6: interleukin-6; iNOS: inducible nitric oxide synthase; LPS: lipopolysaccharide; MFI: mean fluorescence intensity; MHC: major histocompatibility complex; PBS: phosphate buffered saline; PFP-OLNDs: perfluoropentane-based oxygen-loaded nanodroplets; ROS: reactive oxygen species; TNFα: tumor necrosis factor α.
Article Snippet: Surface staining was then performed using 5 μL of the following antibodies: anti-mouse CD45-PE-Cyanine7 (eBioscience, Cat# 25-0459-42, RRID: AB_1944375), anti-mouse major histocompatibility complex (MHC) class II (IA/I-E)-PE (eBioscience, Cat# 12-5321-82, AB_465928), and anti-mouse CD86 (B7-2)-PE-Cyanine5 (eBioscience, Cat# 15-0862-82, AB_468778) for 20 minutes on ice in the dark.
