Figure Lengend Snippet: Fig. 3. STING knockdown inhibits amoebic morphology and pro-inflammatory M1 polarization in microglia. A. Western blotting was used to detect STING after exposure to three different STING siRNAs: STING siRNA-865, STING siRNA-1036, and STING siRNA-1262. B. Quantitative analysis of STING. C. Photograph of BV2 microglial cells with STING knockdown under sevoflurane exposure. D. Western blotting was used to detect inducible nitric oxide synthase (iNOS), cGAS, STING, CD16, and CD32. E–I. Quantitative analysis of iNOS, cGAS, STING, CD16, and CD32, separately. J. An enzyme- linked immunosorbent assay was used to detect tumor necrosis factor-α in the cell supernatant. Data are expressed as the mean ± SD, *P < 0.05, **P < 0.01.
