Dysfunction of the central nervous system (CNS) is a prominent feature of the acquired immune deficiency syndrome (AIDS). Many of these patients have a subacute encephalitis consistent with a viral infection of the CNS. We studied the brains of 12 AIDS patients using in situ hybridization to identify human immunodeficiency virus [HIV, referred to by others(More)
Patterns of demyelination are described in several autoimmune and virus-induced demyelinating diseases of the peripheral and central nervous system. Myelin can be destroyed by injuries that affect either the myelin-supporting cells and/or the myelin lamellae. After destruction of the supporting cells, the related disintegrating sheaths are stripped off(More)
Strains of the murine coronavirus mouse hepatitis virus type 4 (MHV-4) which contained a mutation in the E2 peplomer glycoprotein were obtained by selection for resistance to neutralization by monoclonal antibodies. Characterization of six variants representing two independent epitopes on E2, E2B and E2C, by in vitro neutralization and antibody-binding(More)
Peripheral nerves of diabetic rats were studied 2 years after alloxan injection. We observed demyelination and remyelination, axonal degeneration and regeneration, reduplication of basal laminae around vessels and Schwann's cells, as well as onion bulb formation by proliferated Schwann's cells. Crystalline deposits composed of aggregates of fibrillary(More)
Light microscopic studies on experimental allergic encephalomyelitis (EAE) demonstrated that the morphology of the lesions depends on the intensity and duration of the disease, which may vary from species to species and with the type and mode of administration of the antigen (WOLF et al., 1947; F~g~ARo and ROIZIN, 1954; RolzrN and KoLB, 1959).
