Abstract:
MicroRNAs are small single-stranded, non-coding RNAs which have a known role in post-transcriptional regulation of gene expression. Recent studies have reported that extracellular vesicles are capable of specific delivery of miRNAs to a target cell or tissue from a host cell. MiRNAs are generated by host cells, selectively packaged into EVs, and then delivered to nearby target cells with full functionality. After delivery to the target cells, these EV-packaged miRNAs regulate the translation of their target genes. Thus, EV transported miRNAs have become a newly understood method for intercellular communication. In this review, we summarize the novel findings of EV-miRNA transfer in acute lung injury, chronic obstructive pulmonary disease, bronchopulmonary dysplasia, asthma, and idiopathic pulmonary fibrosis.

Inflammatory Response
Inflammation can be triggered by various stimuli, such as impact, abrasion, chemical irritation, infections, and extreme hot or cold temperatures. These can damage cells and connective tissue fibers,...
Receptor Downregulation in MVBs
The EGFR can initiate signaling pathways that lead to cell proliferation, migration, and differentiation. Overexpression of EGFR stimulates cells to proliferate. Excessive EGFR...
