Neutrophil microRNAs.

Area of Science:

• Immunology
• Cell Biology
• Molecular Biology

Background:

• Neutrophils are critical "first-line defence" immune cells.
• They employ phagocytosis, degranulation, and neutrophil extracellular traps (NETs) to combat pathogens.
• Emerging research highlights neutrophil immunoregulatory roles via secreted mediators, including extracellular vesicles (EVs) containing microRNAs (miRNAs).

Purpose of the Study:

• To review the utility of miRNA molecules as biomarkers for diagnostics in neutrophil-mediated immune reactions.
• To explore the potential of miRNAs as therapeutic targets in these responses.
• To summarize current knowledge on miRNA functions in gene regulation and immune response.

Main Methods:

• Literature review of recent scientific reports.
• Analysis of findings on miRNA molecules within neutrophil-derived EVs.
• Synthesis of information on miRNA's role in gene expression and immune regulation.

Main Results:

• Extracellular vesicles (EVs) secreted by neutrophils contain microRNAs (miRNAs).
• EVs reflect the physiological and pathological state of the releasing cell.
• miRNA molecules are endogenous regulators of gene expression and involved in immune response.
• miRNAs within EVs show promise as biomarkers for diagnostics and potential therapeutic strategies.

Conclusions:

• Neutrophil-derived EVs carrying miRNAs represent a significant area of scientific interest for intercellular communication.
• miRNA molecules hold potential as biomarkers for effective diagnostics in neutrophil-mediated immunity.
• Further research into miRNAs may lead to novel therapeutic strategies for immune-related conditions.
