GluR7 immunoreactivity in taste tissues of TRM5-GFP and GAD67-GFP mice. The expression of GluR7 is shown in circumvallate (CV) papillae in mice expressing GFP (green) under the control of the TRPM5 promoter (A-D) or under the GAD67 promoter (E-H). The GluR7 is co-localized with a subset of GAD67-GFP cells but not with TRPM5-GFP cells suggesting that GluR7 is expressed in a subset of Type III cells. The overlay represents a maximum intensity projection obtained from a z series stack of images, so that the labelled taste cells are not in the same layer.
