The polysialic acid mimetics 5-nonyloxytryptamine and vinorelbine facilitate nervous system repair
Polysialic acid (PSA) is a large negatively charged glycan mainly attached to the neural cell adhesion molecule (NCAM). Several studies have shown that it is important for correct formation of brain circuitries during development and for synaptic plasticity, learning and memory in the adult. PSA also plays a major role in nervous system regeneration following injury. As a next step for clinical...
متن کاملTegaserod mimics the neurostimulatory glycan polysialic acid and promotes nervous system repair
Glycans attached to the cell surface via proteins or lipids or exposed in the extracellular matrix affect many cellular processes, including neuritogenesis, cell survival and migration, as well as synaptic activity and plasticity. These functions make glycans attractive molecules for stimulating repair of the injured nervous system. Yet, glycans are often difficult to synthesize or isolate and ...
متن کاملUse of polysialic acid in repair of the central nervous system.
Polysialic acid (PSA), a large cell-surface carbohydrate that regulates cell interactions, is used during vertebrate development to promote precursor cell migration and axon path-finding. The induction of PSA expression in damaged adult CNS tissues could help them to rebuild by creating conditions permissive for architectural remodeling. This possibility has been explored in two contexts, the r...
متن کاملPolysialic acid-induced plasticity reduces neuropathic insult to the central nervous system.
Under chronic conditions of neuropathic pain, nociceptive C terminals are lost from their target region in spinal lamina II, leading to reduced thermal hyperalgesia. This region of the spinal cord expresses high levels of polysialic acid (PSA), a cell surface carbohydrate known to weaken cell-cell interactions and promote plasticity. Experimental removal of PSA from the spinal cord exacerbates ...
متن کاملSialic acids in the brain: gangliosides and polysialic acid in nervous system development, stability, disease, and regeneration.
Every cell in nature carries a rich surface coat of glycans, its glycocalyx, which constitutes the cell's interface with its environment. In eukaryotes, the glycocalyx is composed of glycolipids, glycoproteins, and proteoglycans, the compositions of which vary among different tissues and cell types. Many of the linear and branched glycans on cell surface glycoproteins and glycolipids of vertebr...
