Depletion of CD4⁺ T cells does not reverse T. muris-mediated protection from papain-induced allergic airway inflammation. (A) Experimental time course of CD4 depletion during the infection/airway challenge model. (B) Bronchoalveolar lavage (BAL) fluid eosinophil counts. (C) Lung mRNA expression of Cd4, Ifng, and Il10 (relative to Actb). Data are means ± SEM, representative of 2 independent experiments (n = 3 to 6 mice per experiment) (B and C). Ctrl, control; Tm, T. muris infected; pap, papain; Rel., relative.
