WebSep 2, 2008 · The important regulatory functions of semaphorin (Sema) and plexin (Plex) family members within the immune system have only recently been appreciated (1–5).In our previous reports, we demonstrated that mature dendritic cells (DCs) express plexin-A1 (Plxna1), which regulates T cell activation (6, 7).Based on these observations, we … WebSurprisingly, we found that VEGF directly controls the expression of Plexin-D1, the receptor for the traditional repulsive axon guidance cue, semaphorin 3E (Sema3E). Sema3E-Plexin …

WebEnables semaphorin receptor activity. Involved in several processes, including negative regulation of cell adhesion; regulation of cell shape; and semaphorin-plexin signaling pathway. Is integral component of plasma membrane. Part of semaphorin receptor complex. [provided by Alliance of Genome Resources, Apr 2024] WebRecent attempts with small molecule drugs have been unsuccessful due to their difficulty interacting with the semaphorin-plexin complex. Matsanuga et al. identified an alternative allosteric site between the Plexin B1 and Semaphorin 4D complex that provided deeper insight into the morphology of these proteins . To circumvent this, nanoparticle ...
WebJul 26, 2010 · Semaphorin 3E (Sema3E) is a secreted molecule implicated in axonal path finding and inhibition of developmental and postischemic angiogenesis. Sema3E is also highly expressed in metastatic cancer cells, but its mechanistic role in tumor progression was not understood. ... Gu C, et al. Semaphorin 3E and plexin-D1 control vascular pattern ... WebJan 14, 2005 · We found that signaling by semaphorin 3E (Sema3E) and its receptor plexin-D1 controls endothelial cell positioning and the patterning of the developing vasculature …
WebJul 14, 2009 · Semaphorin signalling Main Text Semaphorins are multifunctional proteins essential for embryonic development and for various physiological functions in the adult. These proteins interact with members of the plexin and neuropilin families of transmembrane receptors, leading to the activation of a diverse range of intracellular … WebFeb 22, 2024 · The plexin-semaphorin interactions occur in both competitive and cooperative processes, and can involve both forward and reverse signaling cascades. We show that overexpression of Sema2a in larval muscle suppresses the motor and neuronal phenotypes observed when mutant GlyRS is expressed. In contrast, there is no change in …
WebJan 1, 2024 · The semaphorin–plexin and semaphorin–plexin–neuropilin complexes often contain additional proteins, such as receptor protein kinases and cell adhesion molecules, which modulate downstream intracellular signaling pathways critical for cellular function, often in a cell type–specific and tissue-specific manner (Pasterkamp, 2012).
