The frequency of spot-forming cells expressing IFN-γ or IL-2 was determined by ELISPOT. The magnitude of the IFN-γ-secretion response produced by stimulation of splenic lymphocytes in normal mice and Mtb latently infected mice with Ag85b (A), ESAT6 (B), and CFP10 (C) peptides. The secretion of IL-2 cells stimulated by Ag85b (D), ESAT6 (E), and CFP10 (F) peptides was detected in the splenocytes of the two mouse models. */** The infection-CT-AEC/BC02 group was compared with the infection group. #/## The infection-CT-AEC/BC02 group was compared with the infection-CT-BC02 group.
