Transfer of the protective effect with recombinant bacille Calmette–Guérin (rBCG)-induced CD4⁺ CD25⁺ T cells. (a) Protocol for transfer. Approximately 3 × 10⁵ CD4⁺ CD25⁺ T cells were transferred into Der p2-sensitized recipient mice 1 day before airway challenge. (b) Total cell counts and eosinophil numbers in the bronchoalveolar lavage fluid (BALF) from recipients (n = 5). Data represent one of three independent experiments. Labels indicate sensitization/challenge. CFU, colony-forming units; D, Der p2; i.p., intraperitoneal.
