This review covers the molecular pathology of Huntington's disease, focusing on huntingtin protein's role in excitotoxicity. It highlights the involvement of NMDA and kainate receptors in this neurodegenerative process.

Area of Science:

  • Neuroscience
  • Molecular Biology
  • Genetics

Background:

  • Huntington's disease (HD) is a progressive neurodegenerative disorder.
  • Its molecular pathology involves complex genetic and cellular mechanisms.
  • Understanding these mechanisms is crucial for developing effective treatments.

Purpose of the Study:

  • To review recent findings on the molecular pathology of Huntington's disease.
  • To emphasize the role of huntingtin and associated proteins.
  • To explore their involvement in excitotoxicity via specific receptors.

Main Methods:

  • Literature review of recent scientific publications.
  • Analysis of studies focusing on molecular mechanisms in HD.
  • Synthesis of data on protein interactions and receptor function.

Main Results:

  • Huntingtin protein and its associated proteins are implicated in HD pathogenesis.
  • Excitotoxicity, mediated by NMDA and kainate receptors, plays a significant role.
  • These molecular pathways contribute to neuronal dysfunction and death in HD.

Conclusions:

  • The molecular pathology of Huntington's disease is intricate, involving huntingtin protein dysfunction.
  • Targeting excitotoxicity pathways, particularly those involving NMDA and kainate receptors, may offer therapeutic strategies.
  • Further research into these molecular interactions is essential for HD treatment development.
