WebIn order to visualize NMJs, a double-stained with the presynaptic vesicles SV2, and α-bungarotoxin, which label the clusters of postsynaptic acetylcholine receptors (AChR) in the target muscle cells, was performed (Figure 4B). The colocalization of the two signals suggested that axonal projections were correctly associated with the AchR ... WebOct 31, 2014 · AChR cluster size and density in GFP-CLASP2-WT-, GFP-CLASP2–9SXA-, and GFP-CLASP2–8SXD-infected myotubes. AChR cluster sizes and densities (means ± S.D.) obtained from two independent experiments (Exp. 1 and 2) show the correlation of AChR cluster size with CLASP2 phosphorylation. Note that cluster sizes and densities …

WebThe mechanism by which AChR clusters form is not known. AChR clusters have been shown to form in response to a variety of exogenous stimuli such as extracts from neuronal tissue (10, 17) or basal lamina (10, 42) and the application of silk thread (31) and latex beads (39). It has been shown that ~ Abbreviations used in this paper: AChR ... WebMar 1, 2007 · As shown in Fig. 5B, there is a decrease in the number of laminin-induced AChR clusters and AChR microclusters present in the myotubes expressing RhoN19. This effect is similar to the effect of RhoN19 on agrin-induced clusters, although with agrin there is an increase in microclusters (Weston et al., 2003). To confirm that laminin-induced …
WebMar 24, 2024 · In this example, AChR cluster intensity was moderately reduced by 26% after 24 hr in the muscle cell with a very low expression level of MT1-MMP-pHluorin. In contrast, AChR cluster intensity in a muscle cell with a relatively higher (low) MT1-MMP-pHluorin expression showed about 78% reduction during the same period. WebDuring this process, oval, plaque-shaped AChR clusters (Fig. 4a,c) became perforated and acquired a much more complex topology. Some of the remodeled clusters acquired C-shaped topology, in which ...
