After treatment, BV-2 cells were fixed with 4% paraformaldehyde for 20 min then permeated by 0.3% Triton X-100 for 10 min and subsequently blocked by 1% BSA for 20 min. Primary antibodies (galectin-3,
ab76245, Abcam, 1:400; lysosomal associated membrane protein 1, LAMP1,
ab208943, Abcam, 1:400; Lipid A, GTX40001, GeneTex, 1:400; cytosolic phospholipase A2-α, cPLA2, sc-454, Santa Cruz, 1:100; Cyt c, 66264–1, Thermo Fisher, 1:400) were incubated with cells overnight at 4°C. Fluorescence conjugated secondary antibodies (Jackson ImmunoResearch, 711-025-152, 705-095-147, 115-095-003, 715-585-150, 1:200) were added at room temperature for one hour.
After fixing with 4% paraformaldehyde, cells were stained with
BODIPY™ 493/503 (Invitrogen, Life Technologies, Carlsbad, CA, USA) or PI (Beyotime, Shanghai, China) for 20 min at room temperature. TUNEL staining (
MK1027, BOSTER, Wuhan, China) was performed following the manufacturer’s instructions.
Cell nuclei were stained with 4’,6-diamidino-2-phenylindole (DAPI), and all images were captured with fluorescent microscopy (Olympus BX41).
