Abstract:
Microglia represent the main immunocompetent cell type in the parenchyma of the brain and the spinal cord, with roles extending way beyond their immune functions. While emerging data show the pivotal role of microglia in brain development, brain health and brain diseases, the exact mechanisms through which microglia contribute to complex neuroimmune interactions are still largely unclear. Understanding the communication between microglia and other cells represents an important cornerstone of these interactions, which may provide novel opportunities for therapeutic interventions in neurological or psychiatric disorders. As such, in line with studying the effects of the numerous soluble mediators that influence neuroimmune processes, attention on physical interactions between microglia and other cells in the CNS has increased substantially in recent years. In this chapter, we briefly summarize the latest literature on "microglial contactomics" and its functional implications in health and disease.
Insights
Microglia, the brain's immune cells, engage in physical interactions with other cells, a field called "microglial contactomics." Understanding these contacts is key to neuroimmune interactions and potential therapies for brain disorders.
Area of Science:
- Neuroscience
- Immunology
- Cell Biology
Background:
- Microglia are the primary immune cells in the central nervous system (CNS), involved in more than just immune functions.
- Their role in brain development, health, and disease is increasingly recognized, but mechanisms of neuroimmune interaction are unclear.
- Understanding microglia communication is crucial for developing therapies for neurological and psychiatric disorders.
Purpose of the Study:
- To summarize the latest research on "microglial contactomics."
- To explore the functional implications of physical interactions between microglia and other CNS cells in health and disease.
Main Methods:
- Review of recent scientific literature on microglial interactions.
- Focus on physical contact between microglia and other central nervous system cells.
Main Results:
- Emerging data highlight the pivotal role of microglia in brain health and disease.
- Attention has shifted towards physical interactions, complementing studies on soluble mediators.
- "Microglial contactomics" is an emerging field investigating these cellular contacts.
Conclusions:
- Physical interactions between microglia and other cells are critical for neuroimmune processes.
- Investigating "microglial contactomics" offers new therapeutic avenues for CNS disorders.
- Further research into these cellular contacts is essential for advancing our understanding of brain function and disease.
