摘要：

The distribution of neurofilament proteins and peripherin in the pituitary gland of the rat was studied with a panel of monoclonal and polyclonal antibodies recognizing different neurofilament subunits. In the posterior lobe, a dense plexus of neurofilament- and peripherin-immunoreactive fibers was seen. In the intermediate lobe neurofilament- and peripherin-immunoreactivity was seen only in nerve fibers in the connective tissue septa, while no immunoreactivity was seen in parenchymal nerve fibers. Bilateral sympathetic ganglionectomy did not affect peripherin-immunoreactivity, indicating that the peripherin-immunoreactive fibers are of central origin. In the anterior lobe, a few solitary neurofilament- and peripherin-immunoreactive fibers were observed. Western blotting confirmed the presence of 150 kD and 200 kD neurofilament proteins in the posterior lobe. No neurofilament protein was detected in the intermediate and anterior lobes. Abundant intermediate filaments were seen with electron microscopy in the nerve fibers of the connective tissue septa in the intermediate lobe. In the parenchymal nerve fibers only microtubules were seen, indicating that the lack of neurofilament immunoreactivity is due to absence of neurofilaments.
