Figure 6. Intestinal resident macrophages are located in proximity to enteric neurons.

Figure 6

A. Staining of F4/80 positive intestinal resident macrophages (brown) surrounding a myenteric ganglion (blue). Efferent vagus nerve fibers are shown in black. B.1 Regular distribution of resident macrophages (F4/80) in the muscularis of the murine small bowel. B.2 & C. Confocal image showing the distribution of the resident macrophage (F4/80, blue) close to enteric neurons (PGP9.5, red) in the muscle layers of the small intestine. D. Epifluorescence image showing the presence of resident macrophages (F4/80, blue) in close proximity to ChAT positive enteric ganglion (red). Scale bar represents 25 µm, except for B.1 it represents 0.1 mm.
