H. suis-infected animals also displayed increased expression of pro-inflammatory cytokines Il1β and Kc in the corpus of the stomach, which was significant in case of long-term infection (Figure 2E–H), while no changes in expression levels of other inflammatory markers (i.e., Il6, Lix, Il10, Il17a, and Tnf) were demonstrated (data not shown). Here, CALCA is linked to infection.
