Myelin basic protein (MBP) was measured in cerebrospinal fluid (CSF) of patients with acquired immunodeficiency syndrome (AIDS) dementia complex (ADC) in order to investigate the degree of white matter destruction. Results show that increased CSF levels of MBP were detected in all patients with severe ADC (10/10) and, less often, in subjects with mild (2/7)(More)
The polymerase chain reaction (PCR) for detection of cerebral spinal fluid (CSF) Toxoplasma gondii DNA was combined with the study of intrathecal antibody synthesis by antibody specific index calculation (ASI) and the detection of specific oligoclonal IgG bands (OCB) by affinity mediated immunoblotting (AMI) in 11 AIDS patients with T. gondii encephalitis(More)
Tumour necrosis factor (TNF-alpha) concentrations were determined in the CSF from 42 HIV-infected patients, with or without CNS involvement. In addition, 14 subjects with various neurological disorders but without HIV antibodies were included as controls. Raised CSF concentrations of TNF-alpha (greater than 40 ng/l) were detected both in patients with AIDS(More)
After a focal ischemic lesion in the hand representation of the primary motor cortex in squirrel monkeys, manual skill was mildly and transiently impaired on a reach-and-retrieval task. Performance was significantly poorer during weeks 1 and 3 post-lesion, but was normal by week 4. An unusual behavioral event was also observed after the lesion. Monkeys(More)
Progressive multifocal leukoencephalopathy (PML) is a fatal demyelinating disease of the central nervous system (CNS) caused by the human polyomavirus JC (JCV). JCV has a hypervariable noncoding transcriptional control region (TCR) that spans the origin of replication of the JCV genome through to the first ATG start codon for late gene transcription. The(More)
Degradation of purified myelin basic protein (MBP) was studied by SDS gel electrophoresis after addition of CSF samples obtained from HIV-1-infected patients. An increase in MBP degradation was detected in patients with neurological complications, such as AIDS dementia complex (ADC) or progressive multifocal leukoencephalopathy (PML), when compared with(More)
