Fig. 7From: Localization of neonatal Fc receptor for IgG in aggregated lymphoid nodules area in abomasum of Bactrian camels (Camelus bactrianus) of different agesMacrophages and DCs highly expressed FcRn in sLFs in LMFR of young abomasum ALNA. From left to right column, the paraffin sections were stained with hematoxylin and eosin (H&E), immunohistochemistry for FcRn, hematoxylin counterstain (as negative control), respectively. a sLF represents second lymphatic follicles (star) (original magnification: 100×); b GCs represents germinal centers, and many macrophages (arrow) and dendritic cells (DCs) (triangle) with high FcRn expression were seen (original magnification: 1000×); c IFRs represents interfollicular regions, also called B lymphocyte zone, and some DCs (triangle) with high FcRn expression were seen (original magnification: 1000×); d Corona represents corona area, also called B lymphocyte zone, and many DCs (triangle) with high FcRn expression were seen (original magnification: 1000×)Back to article page
