Figure 9. Ultrastructural localization of Ang I/II in the SFO.
(A) Strong expression of Ang I/II (arrows) in the nucleus, cytosol, and vesicular structures of SFO neurons of an uninjected SRAflox mouse. (B) Fragment of cytoplasm of an SFO neuron in A containing immunoreactive vesicular structures (arrows). (C) Note the very low level of immunoreactivity around the neuronal nucleus (arrows) and absence of immunoreactivity in cytoplasm and neuropil after AdCre/AdEGFP was directly injected into the SFO. N, neuron. Scale bars: 2.0 μm (A and C); 1.0 μm (B).
