Immunohistochemistry for H3R in paraffin-embedded liver sections from normal and 1-week BDL rats. By immunohistochemistry (scale bar=50 μm), there was cytoplasmic and membranous staining for H3R in cholangiocytes from normal and BDL rats. H3R were also expressed by hepatocytes from normal and BDL rats. No immunohistochemical reaction was observed when normal or BDL liver sections were incubated with non-immune serum.
