Abstract:
Among the various biological properties presented by Mesenchymal Stem Cells (MSCs), their ability to control the immune response and fight pathogen infection through the production of antimicrobial peptides (AMPs) have been the subject of intense research in recent years. AMPs secreted by MSCs exhibit activity against a wide range of microorganisms, including bacteria, fungi, yeasts, and viruses. The main AMPs produced by these cells are hepcidin, cathelicidin LL-37, and β-defensin-2. In addition to acting against pathogens, those AMPs have also been shown to interact with MSCs to modulate MSC proliferation, migration, and regeneration, indicating that such peptides exert a more diverse biological effect than initially thought. In the present review, we discuss the production of AMPs by MSCs, revise the multiple functions of these peptides, including their influence over MSCs, and present an overview of clinical situations in which the antimicrobial properties of MSCs may be explored for therapy. Finally, we discuss possibilities of combining MSCs and AMPs to generate improved therapeutic strategies.
Insights
Mesenchymal Stem Cells (MSCs) produce antimicrobial peptides (AMPs) that fight infections and modulate MSC functions. This review explores their therapeutic potential in various clinical situations.
Area of Science:
- Stem cell biology
- Immunology
- Antimicrobial research
Background:
- Mesenchymal Stem Cells (MSCs) possess immunomodulatory and antimicrobial properties.
- MSCs secrete antimicrobial peptides (AMPs) like hepcidin, cathelicidin LL-37, and β-defensin-2.
- These AMPs target a broad spectrum of pathogens, including bacteria, fungi, yeasts, and viruses.
Purpose of the Study:
- To review the production of AMPs by MSCs.
- To revise the diverse functions of MSC-derived AMPs, including their impact on MSCs.
- To present an overview of clinical applications for MSC antimicrobial properties.
Main Methods:
- Literature review of studies on MSCs and AMPs.
- Analysis of AMP production mechanisms by MSCs.
- Evaluation of existing and potential therapeutic strategies.
Main Results:
- MSCs are a source of potent AMPs with broad-spectrum antimicrobial activity.
- AMPs produced by MSCs also influence MSC proliferation, migration, and regeneration.
- Clinical applications for MSC-based antimicrobial therapies are being explored.
Conclusions:
- MSC-derived AMPs offer a promising avenue for combating infections.
- Understanding the dual role of AMPs in pathogen defense and MSC modulation is crucial.
- Combining MSCs and AMPs may lead to enhanced therapeutic strategies for infectious diseases.
