Airway hyperresponsiveness (AHR), a hallmark of asthma and several other diseases, can be modulated by γδ T cells. In mice sensitized and challenged with ovalbumin, AHR depends on allergen-specific αβ T cells, but Vγδ1+ γδ T cells spontaneously enhance AHR, whereas Vγ4+ γδ T cells after being induced by airway challenge suppress AHR. The activity of these γδ T cell modulators is allergen-nonspecific, and how they develop is unclear. We now show that CD8 is essential for the development of both the AHR-suppressor and enhancer γδ T cells although neither type needs to express CD8 itself. Both cell types encounter CD8-expressing non-T cells in the spleen, and their functional development in an otherwise CD8-negative environment can be restored with transferred spleen cell preparations containing CD8+ DC, but not CD8+ T cells or CD8− DC. Our findings suggest that CD8+ DC in the lymphoid tissues enable an early step in the development of γδ T cells, through direct cell-contact. DC-expressed CD8 might take part in this interaction.
