Activity-dependent regulation of dendritic complexity by semaphorin 3A through Farp1.
Dendritic arbors are complex neuronal structures that receive and process synaptic inputs. One mechanism regulating dendrite differentiation is Semaphorin/Plexin signaling, specifically through binding of soluble Sema3A to Neuropilin/PlexinA coreceptors. Here we show that the protein Farp1 [FERM, RhoGEF (ARHGEF), and pleckstrin domain protein 1], a Rac1 activator previously identified as a syna...
متن کاملRegulation of dendritic development by Notch signaling
Dendritic patterning exerts a profound influence on neuronal connectivity. Recent studies indicate that mammalian Notch receptors are expressed by postmitotic neurons and that Notch signaling has a considerable influence on dendritic growth and branching. Investigations into the intracellular effectors of dendritic development have revealed that dendritic growth and branching are differentially...
متن کاملRegulation of dendritic development by calcium signaling.
Neuronal activity can have profound effects on dendrite morphology in the developing brain. The effects of neuronal activity on dendritic morphology are mediated by calcium signaling. While many effects of calcium on dendrite structure occur locally at the site of calcium entry into the cytoplasmic milieu, elevation of cytoplasmic calcium is also translated into changes in gene transcription. D...
متن کاملNegative Regulation of Semaphorin-3A Expression in Peripheral Blood Mononuclear Cells Using MicroRNA-497-5p
Background: Semaphorin-3A (Sema3A), as a secreted semaphorin, is an immune modulator molecule participating in the pathogenesis of autoimmune diseases. MicroRNAs (miRNAs) modulate the target-gene expression at the post-transcriptional level. It has been proposed that miRNAs may be crucial to the modulation of the function of semaphorins. Previous findings have proven that miR-497-5p is upregula...
متن کاملSemaphorin 3A elevates endothelial cell permeability through PP2A inactivation.
VE-cadherin-mediated cell-cell junction weakening increases paracellular permeability in response to both angiogenic and inflammatory stimuli. Although Semaphorin 3A has emerged as one of the few known anti-angiogenic factors to exhibit pro-permeability activity, little is known about how it triggers vascular leakage. Here we report that Semaphorin 3A induced VE-cadherin serine phosphorylation ...
