Myeloid-Derived Suppressor Cells in Infection: A General Overview

Area of Science:

• Immunology
• Pathogenesis
• Infectious Diseases

Background:

• Immune responses must be calibrated post-infection to prevent self-damage.
• Suppressor mechanisms mitigate excessive inflammation and tissue injury.
• Myeloid-derived suppressor cells (MDSC) are critical regulators of inflammatory responses.

Purpose of the Study:

• To review the role of MDSC in various infections.
• To highlight how pathogens exploit MDSC functions.
• To summarize current knowledge on MDSC in infectious diseases.

Main Methods:

• Literature review of studies on MDSC and infections.
• Analysis of MDSC's role in bacterial infections.
• Examination of MDSC's involvement in viral, parasitic, and fungal infections.

Main Results:

• MDSC are key in controlling inflammation during infections.
• Pathogens can manipulate MDSC to promote their survival.
• MDSC's dual role impacts infection outcome.

Conclusions:

• MDSC are crucial for immune homeostasis during infection.
• Pathogen exploitation of MDSC can lead to chronic disease.
• Understanding MDSC is vital for managing infectious diseases.
