Insights

Neuroinflammation, involving microglial activation, is key in Alzheimer's disease progression. Positron emission tomography (PET) offers a way to visualize and target these microglial changes for diagnosis and therapy.

Area of Science:

  • Neuroscience
  • Medical imaging
  • Immunology

Background:

  • Neuroinflammation, characterized by microglial activation, is closely linked to neurodegeneration in Alzheimer's disease.
  • Understanding microglial states and phenotypes is crucial for developing effective diagnostic and therapeutic strategies.
  • Positron emission tomography (PET) provides a non-invasive in vivo method to observe molecular changes related to microglial activation in neurological disorders.

Purpose of the Study:

  • To review recent advancements in PET imaging for visualizing microglial activation in Alzheimer's disease.
  • To discuss novel molecular targets for PET-based imaging of microglia.
  • To highlight the potential of PET as a diagnostic and therapeutic tool for neurodegenerative diseases.

Main Methods:

  • Review of preclinical and clinical studies utilizing Positron Emission Tomography (PET).
  • Analysis of molecular targets for imaging microglial activation.
