Other authors have reported increased number of CD68+ macrophages in tissue sections either from biopsies specimens of Crohn’s disease or ulcerative colitis patients or from intestines of DSS-treated mice, corroborating our data (Vong et al., 2012; Hong et al., 2014; Lissner et al., 2015; Reischl et al., 2020). Here, CD68 is linked to Crohn disease.
