Examples of immunoreactive HT7 (A-D), T231 (E-H), and PHF-1 (I-L) nerve
elements (black arrows) within submandibular glands of AD (left) and ND (right)
cases. Immunoreactive ganglion cells (A, E), nerve fibers surrounding an
arteriole (B), stromal nerve fascicles (A, C, E, F, H, J, L), and nerve fibers
intertwined amongst glandular acini (D, G, I, K). Photos were taken at 40x
magnification, except for C, F, and J which were taken at 20x.
