Localization of CRF1 receptors on three different GABAergic populations within the BLA. (A) Colocalization of CRF1 receptors (green) and the calcium-binding protein PV (red). Many somata showed dual-labeling (arrows), but many CRF1 receptor-containing neurons did not express PV (arrowhead). Scale bar: 50 μm. (B) Colocalization of CRF1 receptors (green) and the peptide CCK (red). Many somata showed dual labeling (arrows). Some CCK+ neurons did not express CRF1 receptors (arrowhead). Scale bar: 50 μm. (C) Higher magnification revealed two neurons expressing both CRF1 receptors (green) and CCK (red). Scale bar: 20 μm. (D) Colocalization of CRF1 receptors (green) and the peptide SOM (red). The majority of SOM neurons do not express CRF1 receptors (arrowheads). Scale bar: 50 μm
