High Neto levels affect the BMP signaling.

<p>(A) Confocal images of NMJ4 (segment A4) in larvae of indicated genotypes labeled for GluRIIA (green), pMad (red), and HRP (blue). Excess Neto induced a decrease in the intensity but not number of synaptic GluRIIA and pMad signals (quantified in B-C). All samples were processed and imaged similarly using at least ten NMJs per genotype. Error bars indicate SEM. *; <i>p</i><0.001, **; <i>p</i><0.01, ***; <i>p</i><0.05. Bars: 10 μm.
