Revisiting T Cells in Chronic Rhinosinusitis.

Area of Science:

• Immunology
• Otorhinolaryngology
• Cell Biology

Background:

• Chronic rhinosinusitis (CRS) involves complex immune cell interactions in nasal tissues.
• T cells are critical in CRS immunopathogenesis, producing key cytokines that drive inflammation.

Purpose of the Study:

• To review the multifaceted roles of T cells in CRS pathophysiology.
• To highlight alterations in T cell phenotypes and functions within CRS endotypes.

Main Methods:

• Literature review of recent studies on T cell biology in CRS.
• Analysis of T cell subset alterations in CRS patients.
• Examination of effector and regulatory T cell functions.

Main Results:

• T cells orchestrate immune dysregulation in CRS through cytokine production.
• Specific T cell subsets exhibit altered phenotypes and functions in CRS.
• Functional studies reveal potential therapeutic targets within T cell populations.

Conclusions:

• T cell biology is central to understanding CRS.
• Targeting T cell populations presents promising therapeutic strategies for CRS.
• Further research into T cell-oriented treatments is warranted for CRS management.
