Astrocytes carrying the superoxide dismutase 1 (SOD1G93A) mutation induce wild-type motor neuron degeneration in vivo.

Semenov [28]1 year ago

As "nurse" cells for neurons in the brain parenchyma, astrocytes are resident glial cells produced from neuroectoderm.

How astrocytes become pathological?

  • Recent research has identified astrocytes as major disease-propagating agents in mutant human superoxide dismutase 1 (mSOD1)-mediated amyotrophic lateral sclerosis (ALS).
  • However, due to the widespread expression of mSOD1 throughout the CNS of the investigated rodent models, in vivo examination of a specific astrocytic effect in amyotrophic lateral sclerosis has proven challenging.
  • In order to understand how mutant astrocytes affect WT MNs and other cell types (microglia and astrocytes) in an in vivo environment, we transplanted SOD1(G93A) glial-restricted precursor cells into the cervical spinal cord of WT rats.
  • SOD1(G93A) glial-restricted progenitor cells that were transplanted survived and successfully differentiated into astrocytes.
