Neuroinflammation can be induced under several conditions including pathogen infection such as virus. As the main immune cells in brain, microglia activation plays a pivotal role in neuroinflammation by responding to the invading pathogens (viral DNA/RNA) through toll-like receptors. Chronic activation of microglia caused by sustained viral infection will lead to persistent release of pro-inflammatory...
Background Although microRNA (miRNA) regulation is widely considered as a mechanism to regulate gene expression in metazoans, plants and viruses, there are recent reports that show the interaction between viruses and their mammal hosts via miRNAs produced from both sides. MiRNAs are highly conserved among mammals, whereas the early miRNAs seem to be more diverse, implying a dynamic functional evolution...
MicroRNAs are small non-coding RNAs containing about 18–25 nucleotides which modulate gene expression post-transcriptionally. Recently, microRNAs have been detected in the extracellular space including a wide range of body fluids. These extracellular miRNAs, often encapsulated in secreted extracellular vesicles, can be transferred into recipient cells and thus inhibits the expression of targeted genes...
