Figure 7From: Monoarticular antigen-induced arthritis leads to pronounced bilateral upregulation of the expression of neurokinin 1 and bradykinin 2 receptors in dorsal root ganglion neurons of ratsDisplacement control for SP–gold with the specific NK1 receptor agonist [Sar9, Met(O2)11]-SP in DRG neurons ipsilateral and contralateral to the injected knee. The histograms on the left show the distribution of the grey values after treatment with SP–gold; the histograms on the right show the distribution of the grey values after the administration of SP–gold and [Sar9, Met(O2)11]-SP (1 μmol/ml) together.Back to article page
