HTLV-III-like particles within a cell process surrounded by a myelin sheath in an AIDS brain
Acta Neuropathologica
|January 1, 1987
Abstract:
HTLV-III-like particles were observed within a cell process surrounded by a myelin sheath, in the brain of a 4-year-old boy with AIDS encephalopathy. Similar particles were also observed in the mononuclear macrophage-like cells.
Insights
Human T-lymphotropic virus type III (HTLV-III)-like particles were found in the brain of a child with AIDS encephalopathy. These viral particles were present in both myelin sheath cells and mononuclear macrophage-like cells.
Area of Science:
- Neurology
- Virology
- Pathology
Background:
- Acquired immunodeficiency syndrome (AIDS) can affect the central nervous system, leading to AIDS encephalopathy.
- The presence and role of specific viral agents in the neuropathology of AIDS are critical areas of research.
Purpose of the Study:
- To investigate the presence of human T-lymphotropic virus type III (HTLV-III)-like particles in the brain tissue of a patient with AIDS encephalopathy.
- To identify the specific cell types infected by these viral particles within the affected brain regions.
Main Methods:
- Electron microscopy was utilized to visualize viral particles within brain tissue samples.
- Cellular localization of observed particles was determined through ultrastructural analysis.
Main Results:
- HTLV-III-like viral particles were identified within a cell process ensheathed by myelin.
- Similar viral particles were also detected in mononuclear macrophage-like cells in the brain.
Conclusions:
- The findings suggest that HTLV-III-like viruses may infect cells associated with myelin and macrophages within the brain.
- This observation contributes to understanding the cellular tropism of HTLV-III in the context of AIDS encephalopathy.
