Fig. 3From: Combination therapy with ultrasound and 2D nanomaterials promotes recovery after spinal cord injury via Piezo1 downregulationCombined treatment suppressed inflammation induced by LPS in SIM-A9 cells in vitro. A Confocal laser scanning microscopy images for immunofluorescence staining of SIM-A9 cells treated with LPS, LPS + US, LPS + NPs, and LPS + US + NPs. Cell nuclei were stained with DAPI (blue), and TNF-α was stained with a green signal. B Quantification of TNF-α relative fluorescence intensity in each group. C The expression of inflammation markers (iNOS, TNF-α, and CD86) was analysed by qPCRBack to article page
