However, during cysticercosis caused by T. crassiceps infection, we observed an increased number of parasites in the peritoneal cavity of WT mice at four and eight weeks post-infection (wpi, Figure 1A) which was associated with a Th2-biased profile in the antibody response, with increased IgG1 and total IgE and reduced IgG2a production (Figure 1B) and IL-4 but not IL-13 detection in serum (Figure 1C). Here, IL13 is linked to cysticercosis.
