These phenomena include elaboration of dendritic arborization and formation of synaptic contacts, initially made in excess. Subsequently, refinement occurs, and pruning takes places both at axonal and synaptic level, defining a homeostatic balance maintained throughout the lifespan. All these events require genetic regulations which happens cell-autonomously and are strongly influenced by environmental factors. This review aims to discuss the involvement of guidance cues from the Semaphorin family.Biochemistry & Molecular BiologyChemistry, MultidisciplinaryChemistryamyotrophic lateral sclerosisaxon pruningdendritogenesisneurodegenerationneuromuscular junctionperineuronal netplexinsretinasemaphorinssynaptic plasticitycritical-period plasticitysod1(g93a) mouse modelretinal ganglion-cellsaxon-guidanceparkinsons-diseaseperineuronal netssynapse developmentimmune semaphorinsstructural basissema5a genetext::journal::journal article::review article
