Summary
Nuclear Enriched Abundant Transcript 1 (NEAT1) regulates microglial NLRP3 inflammasome activation, a key driver of neuroinflammation. NEAT1 depletion reduced pro-inflammatory cytokine release, suggesting NEAT1 as a therapeutic target for CNS disorders.
Area of Science:
- Neuroscience
- Immunology
- Molecular Biology
Background:
- Microglia are key immune cells in the central nervous system (CNS).
- Dysregulated microglial activation and NLRP3 inflammasome activation drive neuroinflammation in CNS diseases.
- Long non-coding RNAs (lncRNAs) regulate gene expression and inflammation.
Purpose of the Study:
- To investigate the role of NEAT1 in microglial NLRP3 inflammasome activation.
- To elucidate the mechanisms by which NEAT1 influences neuroinflammation.
Main Methods:
- Utilized in vitro and in vivo models, including NEAT1 knockout mice.
- Employed siRNA to deplete NEAT1 in microglia.
- Assessed NLRP3 inflammasome activation and IL-1β release.
Main Results:
- NEAT1 knockout alleviated NLRP3 inflammasome activation in vivo.
- NEAT1 expression was upregulated upon inflammasome activation in vitro.
- NEAT1 depletion attenuated inflammasome activation and IL-1β release.
- NEAT1 interacts with RNA-binding proteins to regulate inflammasome activation.
Conclusions:
- NEAT1 is a crucial regulator of microglial NLRP3 inflammasome activation.
- Targeting NEAT1 may offer therapeutic strategies for CNS disorders involving neuroinflammation.

9.8K
In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

23.9K
MicroRNA (miRNA) are short, regulatory RNA transcribed from introns—non-coding regions of a gene—or intergenic regions—stretches of DNA present between genes. Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After...

2.9K
Inositol-requiring kinase one or IRE1 is the most conserved eukaryotic unfolded protein response (UPR) receptor. It is a type I transmembrane protein kinase receptor with a distinctive site-specific RNase activity. As the binding mechanics of the misfolded proteins with the N-terminal domain of IRE-1 are unclear, three binding models — direct, indirect, and allosteric -- are proposed for receptor activation. Nevertheless, it is known that once a misfolded protein associates with IRE1, it...
