[Morphological changes in the murine medulla during experimental West Nile virus (strain 986) infection]
Abstract:
The trends in antigen expression and structural changes in the medulla of albino mice infected by West Nile virus (WNV) were studied in different periods of an infectious process, by using monoclonal antibodies to WNV. The maximum amount of immunoreactive material was found in the damaged neurons of dead animals, although WNV antigen expression in the perikaryonic cytoplasm of individual neurons was observed in all the experimental groups. Small amount of neuronal immunoreactive material and its significant levels in the glial cells of symptomatic animals are regarded as a manifestation of individual differences in the neuronal microelement.
Insights
West Nile virus (WNV) infection in mice shows antigen expression in neurons and glial cells. Damaged neurons in deceased animals had the most WNV material, indicating disease progression.
Area of Science:
- Immunology
- Virology
- Neuroscience
Context:
- Investigating the neuropathogenesis of West Nile virus (WNV) infection.
- Examining the temporal dynamics of WNV antigen expression in the mouse medulla.
- Utilizing monoclonal antibodies for precise WNV detection.
Purpose:
- To characterize antigen expression trends and structural changes in the medulla of WNV-infected albino mice.
- To correlate WNV antigen localization with the progression of the infectious process.
- To explore the role of neuronal and glial cells in WNV pathogenesis.
Summary:
- WNV antigen expression was detected in both neuronal and glial cells across all experimental groups.
- The highest concentration of WNV immunoreactive material was observed in damaged neurons of moribund animals.
- Lower neuronal and higher glial cell antigen levels in symptomatic mice may reflect individual variations in neuronal microenvironment.
Impact:
- Provides insights into the cellular tropism and distribution of WNV in the central nervous system.
- Highlights the potential role of glial cells in WNV infection dynamics.
- Contributes to understanding the pathological mechanisms underlying WNV-induced neurological disease.
