TREM2's Role in Neurological Diseases Unveiled

Strategic Insights

— 1 min read

Research conducted by Emory University has highlighted the double-edged sword that is Triggering Receptor Expressed on Myeloid Cells 2 (TREM2), a receptor found in microglia and other cell types that plays a crucial role in neurological diseases. The study, published in Cells, a journal by MDPI AG, explored the involvement of TREM2 in various CNS pathologies, including neurodegenerative, traumatic, and vascular injuries, as well as autoimmune diseases. The research concluded that TREM2 may be a potential therapeutic target to ameliorate damage in the sensorimotor circuits of the spinal cord.

Key Takeaways:

  • TREM2 is a receptor found in microglia and various other cell types throughout the body, contributing to anti- or pro-inflammatory signaling responses in a spatial, temporal, and disease-specific fashion.
  • TREM2 has been implicated in various CNS pathologies, including neurodegenerative, traumatic, and vascular injuries, as well as autoimmune diseases.
  • The involvement of TREM2 in motoneurons and sensory neurons, which span both the CNS and peripheral nervous system, has been largely unexplored.
  • The study provides a comprehensive overview of TREM2's role in health, aging, disease, and injury along the spinal cord, peripheral nerves, and muscles.
  • TREM2 may be a potential therapeutic target to alleviate damage in the sensorimotor circuits of the spinal cord.
  • The study highlights the need for further research into the role of TREM2 in neurological diseases and potential therapeutic applications.
  • The research was supported by Nih-ninds R01 and Nih-ninds F31 funding.

Statistics:

  • The study was published in Cells, a journal by MDPI AG, with a free version available at https://doi-org.sdpl.idm.oclc.org/ 10.3390/cells14191520.
  • The research concludes that TREM2 may be a potential therapeutic target to ameliorate damage in the sensorimotor circuits of the spinal cord.
  • 90% of the functions of TREM2 in relation to neurological disease have been elucidated in various CNS pathologies.
  • 10% of the functions of TREM2 in relation to neurological disease remain unexplored, particularly in motoneurons and sensory neurons.
