Fig. 2From: Mitochondrial DNA drives noncanonical inflammation activation via cGAS–STING signaling pathway in retinal microvascular endothelial cellsMitochondrial permeability transition pore (MPTP) opening was detected with Image-iT™ LIVE Mitochondrial Transition Pore Assay Kit. (A1, B1, C1, and D1) show the fluorescence of calcein (green). (A2, B2, C2, and D2) show MitoTracker Red staining. (A3, B3, C3, and D3) show DAPI staining. (A4, B4, C4, and D4) Merged images of A1–3, B1–3, C1–3, and D1–3, respectively. (a1–4, b1–4, c1–4, and d1–4) Magnification of A1–4, B1–4, C1–4, and D1–4, respectivelyBack to article page
