Annotation description: | Fig. 3, soluble NRP1 (sNRP-1) including the extracellular domain but lacking the cytoplasmic domains is able to block Sema3A ability to induce PSD-95 clusters formation. Literal: "Sema3A concentration dependently increased the density of the PSD-95 immunoreactive clusters per dendrite (Fig. 3A,B). Sema3A also increased the cluster size of PSD-95 (Fig. 3C). To confirm that the clustering of the postsynaptic marker proteins was associated with spine maturation in culture, we compared images of rhodamine-phalloidin staining and PSD-95 clusters. There was an extensive colocalization of PSD-95 clusters with spine-like protrusions after Sema3A treatment (Fig. 3Ad). To confirm a specific effect of Sema3A, we used the construct of sNRP-1. When sNRP-1 was added at the same time as Sema3A in the culture, the sNRP-1 blocked the promoting effect of Sema3A on PSD-95 cluster formation (Fig. 3C)." 6/11/2017 Pim - Authors note in the introduction: 'NRPs are known binders of semaphorins. NRP-1 is necessary for Sema3A-mediated repulsive guidance events (Raper, 2000; Pasterkamp and Kolodkin, 2003; Fujisawa, 2004)" |
