Immunolocalization of tyrosine hydroxylase and vasoactive intestinal polypeptide in nerve fibers innervating human palatine tonsil and paratonsillar glands.
The presence of tyrosine hydroxylase (TH) and vasoactive intestinal polypeptide (VIP) in the nerve fibers of the human palatine tonsil and paratonsillar secretory glands is reported. By immunohistochemistry TH-immunoreactive nerves and those immunoreactive to VIP were localized to the tonsil, in particular, the tonsillar vessel wall, extranodular lymphoid tissue and lymph nodule, and to the acinar basal surface of the paratonsillar glands. In the lymph nodule, immunoreactive varicose nerve profiles were observed inside the marginal zone. The germinal center was devoid of immunoreactive fibers.
