Semaphorin 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 ...
متن کاملBrain Endothelial Cells Control Fertility through Ovarian-Steroid–Dependent Release of Semaphorin 3A
Neuropilin-1 (Nrp1) guides the development of the nervous and vascular systems, but its role in the mature brain remains to be explored. Here we report that the expression of the 65 kDa isoform of Sema3A, the ligand of Nrp1, by adult vascular endothelial cells, is regulated during the ovarian cycle and promotes axonal sprouting in hypothalamic neurons secreting gonadotropin-releasing hormone (G...
متن کاملEndothelial cell-derived semaphorin 3A inhibits filopodia formation by blood vascular tip cells.
Vascular endothelial growth factor (VEGF)-A is a well-known major chemoattractant driver of angiogenesis--the formation of new blood vessels from pre-existing ones. However, the repellent factors that fine-tune this angiogenic process remain poorly characterized. We investigated the expression and functional role of endothelial cell-derived semaphorin 3A (Sema3A) in retinal angiogenesis, using ...
متن کاملMeningeal cell-derived semaphorin 3A inhibits neurite outgrowth.
The neural scar that forms after injury to the mammalian central nervous system is a barrier to sprouting and regenerating axons. In addition to reactive astrocytes that are present throughout the lesion site, leptomeningeal fibroblasts invade the lesion core. When isolated in vitro, these cells form a very poor substrate for growing neurites, even more so than reactive astrocytes. Nevertheless...
متن کاملSemaphorin 3A suppresses VEGF-mediated angiogenesis yet acts as a vascular permeability factor.
Semaphorin 3A (Sema3A), a known inhibitor of axonal sprouting, also alters vascular patterning. Here we show that Sema3A selectively interferes with VEGF- but not bFGF-induced angiogenesis in vivo. Consistent with this, Sema3A disrupted VEGF- but not bFGF-mediated endothelial cell signaling to FAK and Src, key mediators of integrin and growth factor signaling; however, signaling to ERK by eithe...
