Figure 3: Immunodetection of tyrosine hydroxylase and parvalbumin in the
retina of P. obesus. Tyrosine hydroxylase immunostaining was intense in
plexiform layers in control (B, arrow) but it was reduced in diabetic animals
(E, asterisk). Histological sections of P. obesus retina immunostained with
parvalbumin antibody were very similar in control (C) and diabetic animals (F).
Bar in F=50μm for all panels. Abbreviation: GCL: Ganglion Cell Layer; INL: Inner Nuclear Layer; IPL: Inner Plexiform Layer; ONL: Outer Nuclear Layer; OPL: Outer Plexiform Layer; OS: Outer Segments; ND: Natural Diet; HDD: High-protein Diet Diabetic. |
