FIG. 3.

Cytolytic effect of rmTNF-α on T. cruzi trypomastigotes. T. cruzi trypomastigotes were treated with rmTNF-α or with rmTNF-α preincubated with either anti-TNF-α MAb 1F3F3, an anti-TNF-α TIP MAb, (▴), or N,N′-diacetylchitobiose. T. cruzi epimastigotes were not lysed by rmTNF-α. Data are means ± SEM of three independent experiments performed in triplicate.
