Semaphorins and plexins
WebExpression of the axon guidance molecules Semaphorins (SEMAs), which signal through Plexins and Neuropilins (NRPs), have been associated with liver fibrosis in HBV-induced chronic hepatitis. This study aims at determining their function in the regulation of HSCs. We analyzed publicly available patient databases and liver biopsies. WebSemaphorins are soluble or membrane-bound cues, which control multiple aspects of cell-cell communication, differentiation, morphology and function. Most of their effects are mediated by a family of transmembrane receptors called plexins. Semaphorins and plexins have emerged as central regulators of … Semaphorins and Plexins in Kidney Disease

WebFeb 1, 2024 · Semaphorins and Plexins are crucial proteins in patterning central nervous system. • Local and cerebrospinal fluid-derived Semaphorins/Plexins influence … WebMost Semaphorins use receptors in the group of proteins known as plexins. Class 3 semaphorins signal through heterocomplexes of neuropilins, Class A Plexins, and cell adhesion molecules, and the makeup of these complexes likely provides specificity for binding and transducing signals from different Class 3 Semaphorins.
WebSemaphorins are a family of growth cone guidance molecules. When associated with their receptors and coreceptors, plexins and neuropilins, they act as chemorepellents for an extensive range of neuronal populations. The prototypic semaphorin, Sema3A, has a potent inhibitory effect on sensory axons emanating from dorsal root ganglia. WebApr 11, 2024 · Semaphorins and Plexins may act cell autonomously on motor neurons or non-cell autonomously on neighbouring motor neurons to maintain their survival.
