adventitial cell

In regards to his discovery of "Kupffer cells" in 1876, he initially suggested that this type of cell belonged to a group of perivascular cells of the connective tissues or to the adventitial cells (pericytes).

Meningoencephalitis characterized by perivascular cuffing with proliferating adventitial cells, histiocytes, and a few plasma cells was seen in the gray and white matter of the cerebrum and in the leptomeninges of PPV-infected stillborn pigs.
