MHC class I-dependent Vγ4 ⁺ pulmonary T cells regulate αβ T cell-independent airway responsiveness

Abstract excerpt

Mice exposed to aerosolized ovalbumin (OVA) develop increased airway responsiveness when deficient in gammadelta T cells. This finding suggests that gammadelta T cells function as negative regulators. The regulatory influence of gammadelta T cells is evident after OVA-sensitization and -challenge, and after OVA-challenge alone, but not in untreated mice. With aerosolized Abs to target pulmonary T cells, we now...
