Expression of insulin-responsive glucose transporter GLUT4 mRNA in the rat brain and spinal cord: an in situ hybridization study.

Induction of cell death in rat brain by a gliotoxic factor from cerebrospinal fluid in multiple sclerosis.

The cerebrospinal fluid (CSF) of multiple sclerosis (MS) patients contains a 17 kDa glycoproteic factor with gliotoxic properties in vitro. In order to study the physiopathological role of this gliotoxic factor in vivo, we have injected a partially purified preparation and appropriate controls in rat CSF and investigated whether it induces cell death in the rat central nervous system (CNS), 10 days and 3 months after injection. We used the TUNEL assay in association with specific immunohistochemistry to characterize dying cells in the gliotoxic factor- treated rat CNS.
