CD14(hi) HLA-DRdim macrophages, with a resemblance to classical blood monocytes, dominate inflamed mucosa in Crohn's disease
The increase of CD14(+) lamina propria macrophages in active Crohn's disease is due to a subset discriminated by HLA-DR, likely from CD16(-) blood monocytes. Intestinal M phi play an important role in maintaining gut homeostasis. However, little is known about these cells, their precursors, and their role in intestinal inflammation. Here, we characterize the CD14(+) mononuclear cell populations in
