However, emerging evidence underscores the critical roles of innate T cells, such as invariant natural killer T (iNKT), mucosal-associated invariant T (MAIT), and γδ T cells, in airway inflammatory diseases. These innate T cells are enriched in sinonasal tissues and contribute to mucosal inflammation through cytokine production, exhibiting functional polarization that reflects local inflammatory cues. In particular, MAIT17 and Vγ1⁺ γδ T cells have been associated with tissue eosinophilia and disease severity in patients with eosinophilic CRSwNP, whereas iNKT cells display subset-specific distributions across eosinophilic and neutrophilic endotypes. In asthma, iNKT cells consistently contribute to disease development in murine models, whereas the functions of MAIT and γδ T cells remain controversial, showing both pro- and anti-inflammatory effects depending on anatomical location and disease context.
