[Inhibition of excretory - secretory antigens on growth of murine Lewis lung carcinoma].

Objective: To investigate the effect of excretory-secretory antigens (ESA) on CD4 CD25 Foxp3 T (Treg) cells in mice carrying Lewis lung carcinoma, and examine the inhibitory effect of ESA on tumor growth.

Methods: C57BL/6 mice were randomly assigned into the PBS group ( = 14) and the Lewis group ( = 34). Mice in the Lewis group were subcutaneously injected with 2 × 105 Lewis lung carcinoma cells in the right axilla, while animals in the PBS group were injected with the same volume of sterile PBS.
