  • We conclude that these bioengineered neural circuit model systems are reliable and scalable tools to accurately study aspects of human astrocyte-neuron functional properties while being easily accessible for cell-type-specific manipulations and observations. (cornell.edu)

  • Mitochondrial dysfunction is one of the major intracellular lesions of Alzheimer's disease (AD). (jneurosci.org)
  • However, the causative factors involved in the mitochondrial dysfunction in human AD are not well understood. (jneurosci.org)
  • Notably, we found that female cells were overrepresented in disease-associated subpopulations, and that transcriptional responses were substantially different between sexes in several cell types, including oligodendrocytes. (nature.com)
  • 2018). We demonstrate that human microglial cells are recruited toward 3D AD (amyloid beta-producing) neuron-astrocyte cultures via microglia-specific migration channels, in a chemokine-dependent manner, leading to neuroinflammation and neurodegeneration. (curealz.org)
