Barrier Tissue-Resident Macrophages: Natural Compounds as Modulators in Immune Function and Disease

Area of Science:

• Immunology
• Cell Biology
• Pharmacology

Background:

• Tissue-Resident Macrophages (TRMs) are crucial immune cells residing in barrier tissues like skin, lungs, and intestines.
• TRMs originate from early progenitor cells and possess unique features for local immune responses and tissue homeostasis.
• Their functional plasticity allows adaptation to microenvironments, supporting roles in repair, inflammation, and immune surveillance.

Purpose of the Study:

• To review the critical role of TRMs in immune responses.
• To explore the potential of Natural Compounds (NCs) in modulating TRM function.
• To highlight NCs as a therapeutic strategy for inflammatory and immune-related diseases.

Main Methods:

• Literature review of studies on TRMs and Natural Compounds (NCs).
• Analysis of research on NCs' effects on macrophage activation and function.
• Synthesis of findings on TRM modulation by NCs for therapeutic applications.

Main Results:

• TRMs are vital for tissue health and immune defense.
• Natural Compounds (NCs) can significantly influence macrophage activities, either enhancing or suppressing them.
• Evidence suggests NCs can modulate TRM activation and function, impacting immune responses and healing.

Conclusions:

• Understanding TRMs is essential for developing new therapies.
• Natural Compounds (NCs) offer a promising avenue for modulating TRM function.
• Targeting TRMs with NCs could lead to innovative treatments for immune-related diseases.
