Macrophages 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×)
