Abstract

Glial cells that contain the glial fibrillary acidic protein (GFAP; the major protein constituent of glial filaments) were stained immunohistochemically in thick frozen sections of the neurohypophysis of the Mongolian gerbil (Meriones unguiculatus). The resulting Golgi-like images provided informations on cytological features and distributional patterns of tanycytes and pituicytes. In the proximal median eminence, numerous bundled processes of tanycytes were revealed. They emerged from the ependymal and sub-ependymal layer and mostly reached the brain surface. Several tanycytic processes extended into the anatomical neural stalk. In the whole neural lobe, a dense network of GFAP-immunoreactive pituicyte processes was visualized. Stained pituicytes were highly asymmetric and exhibited a great morphological variability. Immunopositive fibers which were encountered in the intermediate lobe might be derived from pituicytes. Electron-microscopically further evidence was obtained that GFAP-positive pituicytes correspond to filament-rich fibrous pituicytes at the ultrastructural level.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.
