Dual immunolabeling of gp91^phox and TH in mNTS neurons or astroglia. (A). A dual labeled dendritic profile (gp91-TH-d) displays diffuse immunoperoxidase reaction product for TH. Immunogold particles (small closed arrows) are present intracellularly and near the surface membrane adjacent to an unlabeled axon terminal (ut). (B). A single gp91^phox labeled dendritic profile (gp91-d) contains intracellular immunogold labeling (small closed arrows), including near a mitochondria (m). This dendrite receives an asymmetric type synapse (curved closed arrow) from an axon terminal (TH-t) showing dense immunoperoxidase reaction product for TH. (C). A single labeled glial process (gp91-g) contains dispersed immunogold particles (small closed arrows) near a vesicular organelle (vo) and the plasmalemma. This glia is contacted by numerous neuronal profiles, including an unlabeled axon terminal (ut) and a small immunoperoxidase labeled unmyelinated axon (TH-a). Scale Bars = 0.5 μm.
