Effect of Trehalose on Neurocan and Neural-Glial Antigen 2 Genes Expression in Rats with Spinal Cord Injury
Background: Chondroitin sulfate proteoglycans (CSPGs) are the major cause of axonal regeneration failure at the site of lesion in spinal cord injury (SCI). Inflammation is believed to stimulate the upregulation of CSPGs expression. Recent evidence showed that trehalose reduces the development of inflammation in SCI. The aim of this study was to investigate the effect of trehalo...
متن کاملEntrapment via synaptic-like connections between NG2 proteoglycan+ cells and dystrophic axons in the lesion plays a role in regeneration failure after spinal cord injury.
NG2 is purportedly one of the most growth-inhibitory chondroitin sulfate proteoglycans (CSPGs) produced after spinal cord injury. Nonetheless, once the severed axon tips dieback from the lesion core into the penumbra they closely associate with NG2+ cells. We asked if proteoglycans play a role in this tight cell-cell interaction and whether overadhesion upon these cells might participate in reg...
متن کاملUnderstanding the NG2 Glial Scar after Spinal Cord Injury
NG2 cells, also known as oligodendrocyte progenitor cells, are located throughout the central nervous system and serve as a pool of progenitors to differentiate into oligodendrocytes. In response to spinal cord injury (SCI), NG2 cells increase their proliferation and differentiation into remyelinating oligodendrocytes. While astrocytes are typically associated with being the major cell type in ...
متن کاملNG2 glial cells provide a favorable substrate for growing axons.
NG2 cells (polydendrocytes) comprise an abundant glial population that is widely and uniformly distributed throughout the developing and mature CNS and are identified by the expression of the NG2 proteoglycan at the cell surface. Although recent electrophysiological studies suggest that they are capable of receiving signals from axon terminals, other studies, based on the finding that the NG2 m...
متن کاملThe role of the desert hedgehog signaling pathway during degeneration and regeneration of peripheral nerves
The desert hedgehog (Dhh) signaling pathway is involved in the development of peripheral nerves (PNs). Dhh-null mice show abnormal neuronal development and perineurial barrier function. As it was previously shown that dhh is mainly expressed in developmental nerves and Sonic hedgehog protein (dhh homologous) has therapeutic effects in neuronal survival, we attempted to investigate the possible ...
