Formation of fibroblastic reticular network in the brain after infection with neurovirulent murine coronavirus.

ABSTRACT: cl-2 virus is an extremely neurovirulent murine coronavirus. However, during the initial phase of infection between 12 and 24 h post-inoculation (hpi), the viral antigens are detected only in the meninges, followed by viral spread into the ventricular wall before invasion into the brain parenchyma, indicating that the viruses employ a passage between the meninges and ventricular wall as an entry route into the brain parenchyma. At 48 hpi, the passage was found to be constructed by ER-TR7 antigen (ERag)-positive fibers (ERfibs) associated with laminin and collagen III between the fourth ventricle and meninges at the cerebellopontine angle. The construct of the fibers mimics the reticular fibers of the fibroblastic reticular network, which comprises a conduit system in the lymphoid organs. I
