Abstract:
Neurological disorders cause untold human disability and death each year. For most neurological disorders, the efficacy of their primary treatment strategies remains suboptimal. Microglia are associated with the development and progression of multiple neurological disorders. Targeting the regulation of microglia polarization has emerged as an important therapeutic strategy for neurological disorders. Their pro-inflammatory (M1)/anti-inflammatory (M2) phenotype microglia are closely associated with neuronal apoptosis, synaptic plasticity, blood-brain barrier integrity, resistance to iron death, and astrocyte regulation. LncRNA, a recently extensively studied non-coding transcript of over 200 nucleotides, has shown great value to intervene in microglia polarization. It can often participate in gene regulation of microglia by directly regulating transcription or sponging downstream miRNAs, for example. Through proper regulation, microglia can exert neuroprotective effects, reduce neurological damage and improve the prognosis of many neurological diseases. This paper reviews the progress of research linking lncRNAs to microglia polarization and neurological diseases.
Insights
Long non-coding RNAs (lncRNAs) show promise in regulating microglia polarization, offering a new therapeutic avenue for neurological disorders by modulating their M1/M2 phenotypes to reduce neuroinflammation and damage.
Area of Science:
- Neuroscience
- Molecular Biology
- Genetics
Background:
- Neurological disorders cause significant disability and death, with treatments often having suboptimal efficacy.
- Microglia, the immune cells of the central nervous system, are implicated in the pathogenesis of various neurological conditions.
- Modulating microglia polarization (pro-inflammatory M1 vs. anti-inflammatory M2) is a key therapeutic strategy.
Purpose of the Study:
- To review the current research on the role of long non-coding RNAs (lncRNAs) in microglia polarization.
- To explore how lncRNAs influence microglia phenotypes and their impact on neurological disease progression.
- To highlight the therapeutic potential of targeting lncRNAs for neurological disorders.
Main Methods:
- Literature review of studies investigating lncRNAs, microglia polarization, and neurological diseases.
- Analysis of mechanisms by which lncRNAs regulate microglia gene expression (e.g., transcription, miRNA sponging).
- Synthesis of findings on the neuroprotective or detrimental effects of lncRNA-mediated microglia modulation.
Main Results:
- lncRNAs are increasingly recognized as critical regulators of microglia polarization.
- lncRNAs can influence M1/M2 microglia balance, affecting neuronal apoptosis, synaptic plasticity, and blood-brain barrier integrity.
- Specific lncRNAs demonstrate potential in mitigating neurological damage and improving disease outcomes.
Conclusions:
- lncRNAs represent a promising target for therapeutic intervention in neurological disorders.
- Understanding lncRNA-microglia interactions is crucial for developing novel treatment strategies.
- Further research into lncRNA functions can unlock new pathways for neuroprotection.
