Fig. 9. Representative micrographs of MOR-SIG particles in PARV-containing interneurons in the hilus of the dentate gyrus from Sal- and Oxy-CIS rats.

Fig. 9.

A. Low magnification light microscopic photomicrograph shows PARV-labeled cells are primarily located in the subgranular region of the dentate gyrus (gcl = granule cell layer). B. Electron micrograph shows example of a somata in the subgranular zone of the hilus dually labeled for MOR (SIG particles) and PARV (immunoperoxidase; N = nucleus). C-F. Electron micrographs show the distribution of MOR-SIG particles within peroxidase-labeled PARV dendrites in the DG from a Sal-CIS female (C), an Oxy-CIS female (D), a Sal-CIS male (E), and an Oxy-CIS male (F) rat. Triangles and arrows indicate near plasmalemmal and cytoplasmic MOR-SIG particles, respectively. PARV-labeled dendrites are often contacted by unlabeled terminals (T). Scale bars: 500 μm (A); 500 nm (B-F).
