However, compared to the ghrelin-treated and non-infected groups (CG), the infection with T. cruzi (I) stimulated the T cell proliferation only the samples incubated with CoA (post-hoc test: P < 0.0001) and T. cruzi (post-hoc test: P = 0.0002) for 4 days (Fig. 6d and f). This evidence concerns the gene GHRL and infection.
