Abstract:
Microglia are the main resident macrophage population of the CNS and perform numerous functions required for CNS development, homeostasis, immunity, and repair. Many lines of evidence also indicate that dysregulation of microglia contributes to the pathogenesis of neurodegenerative and behavioral diseases. These observations provide a compelling argument to more clearly define the mechanisms that control microglia identity and function in health and disease. In this Review, we present a conceptual framework for how different classes of transcription factors interact to select and activate regulatory elements that control microglia development and their responses to internal and external signals. We then describe functions of specific transcription factors in normal and pathological contexts and conclude with a consideration of open questions to be addressed in the future.
Insights
Microglia, the brain's immune cells, are crucial for CNS health. Understanding the transcription factors controlling their function is key to addressing neurodegenerative diseases.
Area of Science:
- Neuroscience
- Immunology
- Genetics
Background:
- Microglia are the primary immune cells in the central nervous system (CNS).
- Microglia play vital roles in CNS development, homeostasis, immunity, and repair.
- Dysregulation of microglia is implicated in neurodegenerative and behavioral diseases.
Purpose of the Study:
- To present a conceptual framework for transcription factor interactions in microglia.
- To elucidate mechanisms controlling microglia identity and function in health and disease.
- To review the roles of specific transcription factors in normal and pathological CNS conditions.
Main Methods:
- Conceptual framework development.
- Literature review of transcription factor functions.
- Analysis of regulatory elements controlling microglia.
Main Results:
- A framework is proposed detailing how transcription factors regulate microglia development and responses.
