FIG. 1.
L. amazonensis infection in mice following adoptive transfer of Th1 cells. Groups of five to eight C57BL/6 mice were intravenously injected with 107 S1A Th1 cells or with PBS alone 1 day prior to infection with 2 × 106 stationary-phase promastigotes (A) or 105 tissue-derived amastigotes (B). Parasite burdens were assayed at 10 weeks after promastigote infection (A) or at 6 weeks after amastigote infection (B). (Insets) Lesion sizes at different times. The data represent the data from three independent experiments.
