Abstract:
A wide variety of studies have identified microglial activation in psychiatric disorders, such as schizophrenia, bipolar disorder, and major depressive disorder. Relatively fewer, but robust, studies have detected activation of peripheral monocytic cells in psychiatric disorders. Considering the origin of microglia, as well as neuropsychoimmune interactions in the context of the pathophysiology of psychiatric disorders, it is reasonable to speculate that microglia interact with peripheral monocytic cells in relevance with the pathogenesis of psychiatric disorders; however, these interactions have drawn little attention. In this review, we summarize findings relevant to activation of microglia and monocytic cells in psychiatric disorders, discuss the potential association between these cell types and disease pathogenesis, and propose perspectives for future research on these processes.
Insights
Microglial and monocytic cells are activated in psychiatric disorders. This review explores their potential interactions and roles in disease pathogenesis, highlighting areas for future research.
Area of Science:
- Neuroscience
- Immunology
- Psychiatry
Background:
- Microglial activation is common in psychiatric disorders like schizophrenia and depression.
- Peripheral monocytic cell activation is also observed, though less studied.
- Neuropsychoimmune interactions are crucial in psychiatric disorder pathophysiology.
Purpose of the Study:
- To review microglial and monocytic cell activation in psychiatric disorders.
- To discuss the potential association between these cells and disease pathogenesis.
- To propose future research directions.
Main Methods:
- Literature review of studies on microglial and monocytic cell activation in psychiatric disorders.
- Analysis of neuropsychoimmune interactions.
- Synthesis of current findings and identification of research gaps.
Main Results:
- Consistent evidence for microglial activation across various psychiatric disorders.
- Growing evidence for peripheral monocytic cell involvement.
- Limited research on the interaction between microglia and monocytic cells in psychiatric disorders.
Conclusions:
- Microglia and peripheral monocytic cells are implicated in psychiatric disorders.
- Their interactions may play a significant role in disease pathogenesis.
- Further research is needed to elucidate these interactions and their therapeutic potential.
