PTPRC and colitis: Also evident when assessing the overall immune make-up of CD45+ cells was that although DSS-induced colitis significantly increased the proportion of neutrophils in the gut of Jα18−/− mice to a greater extent than in WT mice (Figure S6A in Supplementary Material), there were no significant differences between the proportions of monocytes and T cells between post-DSS WT mice and Jα18−/− mice (Figures S6B,C in Supplementary Material).
