Th17/Treg Imbalance: Implications in Lung Inflammatory Diseases

Area of Science:

• Immunology
• Cell Biology
• Respiratory Medicine

Background:

• Regulatory T cells (Tregs) maintain immune homeostasis.
• T helper 17 cells (Th17) promote inflammation.
• Both Treg and Th17 cells are implicated in inflammatory diseases.

Purpose of the Study:

• To review the current understanding of Treg and Th17 cell functions.
• To focus on the roles of these cells in various lung inflammatory diseases.

Main Methods:

• Literature review of recent studies.
• Analysis of the involvement of CD4+ T cell subsets in respiratory conditions.

Main Results:

• Th17 cells and Tregs exhibit antagonistic functions.
• These T cell subsets are central to the pathogenesis of lung inflammatory diseases.

Conclusions:

• Tregs and Th17 cells are critical players in lung inflammation.
• Understanding their balance is vital for treating diseases like COPD, ARDS, asthma, and infections.
