Immunostaining of Crohn’s disease mesenteric adipose tissue (MAT) showed an increase in B, T and plasma cell infiltration. a Immunohistochemical analysis of CD45, CD20, CD3 and CD138 were performed on paraffin-embedded slides from the MAT of CD and CTR groups. The arrows show cells positive to the staining. 20× objective lens was used. b Double-immunofluorescent staining of CD20 with CD3 or IgG was performed on paraffin-embedded slides from the MAT of CD and CTR groups. Positive cells for CD20 are shown in red, while positive cells for CD3 and IgG are shown in green. 20× objective lens was used
