Photomicrographs illustrating Iba-1 microglial marker immunostaining (green) and cell nuclei stained with DAPI (blue) from commissural and intermediate NTS (a, b, magnification × 2.5). High magnification from Sal (3 h), LPS (3 h), and LPS (24 h) groups (c) showing the number of microglia cells in the intermediate NTS region (magnification × 10). The inset on the upper right is showing microglial morphology in the intermediate NTS (c, magnification × 20). Central canal (CC)
