Figure 4. NPY expression in ensheathing cells in the olfactory bulb is inhibited by intranasal instillation of ATP.

Figure 4

Z-stack images of NPY-IR in the olfactory nerve layer and bulbs. (A) Intranasal instillation of ATP inhibits the NPY-IR in the olfactory ensheathing cells. Inset: representative cryostat section depicting the region from which images A–D were taken. Scale bars = 20μm. Dashed line distinguishes the outer nerve layer (ONL) from the glomeruli (G). (B) NPY-IR (green) was not co-localized with olfactory sensory neuron marker olfactory marker protein (OMP)-IR (red). Thin arrows, single localization of NPY. (C) The NPY-IR (green) between glomeruli was co-localized with p75 (red). Thick arrows, co-localization of NPY. (D) NPY-IR in the outer nerve layer was co-localized with s100-β (red).
