Immunohistochemical profiles of high endothelial venules (HEVs) in human peripheral lymph nodes (PLNs), mesenteric LNs (MLNs) and Peyer’s patches (PPs). Serial sections of indicated tissues were immunostained for MECA-79, 297-11A or 5D4. For 297-11A staining, sections were treated with (w/) or without (w/o) HCl, and HCl-treated sections were further treated with peptide N-glycanase F (PNGase F). Signals were visualized with 3,3′-diaminobenzidine (brown), and tissues were counterstained with hematoxylin. Bar = 40 μm
