Salbutamol treatment alters MuSK immunoreactivity in ColQ−/− mice. A. AChR and MuSK clusters labelled with Alexa 488 α-BTX (green, AChR) and anti-MuSK antibody (red) respectively on transverse sections of gastrocnemius muscle from 10-wk-old WT, water treated ColQ−/− (ColQ−/− WFI) and salbutamol treated ColQ−/− (ColQ−/− SAL) mice. Scale bar, 20 μm. B. Quantification of MuSK fluorescence intensities from projection of confocal stacks. MuSK fluorescence intensity per AChR cluster was decreased in ColQ−/− muscle, and significantly increased in salbutamol treated ColQ−/− mice compared to water treated. n = 180 NMJs per group for B. Unpaired Student’s t tests. ∗∗∗p < 0.001, p < 0.05, n.s. not significant.
