Mechanism of Neuronal Migration in Human Foetal Cerebrum In-vitro

Choi BH

Active migration of immature neurons occurs when fragments of human foetal cerebral tissues are explanted as organotypic cultures. The sequence of events during neuronal migration is orderly and consistent under...

Interleukin-10 endogenously expressed in microglia prevents lipopolysaccharide-induced neurodegeneration in the rat cerebral cortex in vivo

Park KW, Lee HG, Jin BK, Lee YB

  • KMID: 1091076
  • Exp Mol Med.
  • 2007 Dec;39(6):812-819.
A degree of brain inflammation is required for repair of damaged tissue, but excessive inflammation causes neuronal cell death. Here, we observe that IL-10 is expressed in LPS-injected rat cerebral...

Calcium overload is essential for the acceleration of staurosporine-induced cell death following neuronal differentiation in PC12 cells

Seo SR, Seo JT

Differentiation of neuronal cells has been shown to accelerate stress-induced cell death, but the underlying mechanisms are not completely understood. Here, we find that early and sustained increase in cytosolic...
