GR and MR immunoreactivity in the nucleus and perikaryon.

<p>(A) Supporting light level qualitative analysis, immunoreactivity was observed in the nuclear compartment of GR-ir labeled LA neurons and (B) MR-ir (rMR1-18 1D5) labeled neurons compared to primary antibody omitted control slices (C). Little immunoreactivity was observed in the nucleus of LA neurons labeled with the MR antibody MA1-620. MR immunoreactivity with both antibodies was observed on cytosolic structures including the Golgi Apparatus and cell membrane (B). Scale bars = 500 nm.
