GITR activation does not alter antibody production.

<p>C57BL/6 mice were treated or not with 500 μg of DTA-1 one day before experimental infection. In the control group, PBS was administered. Infection was performed with 20 cysts injected i.p. A blood sample was collected on days 10, 20 and 30 after infection. Levels of IgG1 (A), IgG2a (B), Total IgG (C) and IgG2a/IgG1 ratio (D) were assessed by ELISA. Error bars indicate mean +/- SEM (n = 5/group).
