In the periparasitic infiltrate area, IL-17, disclosed by immunostaining (Figure 4A), was observed in most lymphocytes and macrophages in the periparasitic infiltrate, as well as in fibroblasts, and endothelial cells in hepatic sinusoids, especially around the granulomas, and in infiltrating immune cells of portal spaces, from day 8 to day 360 p.i.. This evidence concerns the gene IL17A and Granuloma.
