Fig 5. Immunoreactivity against the adenosine A₁ and A₃ receptors in rats simultaneously having hypertension and diabetes.

Representative photomicrographs of kidney sections from 4 SHR-STZ rats incubated with a primary antibody against the adenosine A₁ (left panels) and A₃ (right panels) receptors. The six renal structures studied in separate are represented: superficial (SG) and deep glomeruli (DG), proximal (PCT) and distal (DCT) convoluted tubule, loop of Henle (LH) and collecting tubule (CT). Scale bars: 20 μm.
