Detection by immunofluorescence of avian myeloblastosis virus reverse transcriptase
Acta Virologica
|August 1, 1976
Abstract:
Peripheral blood cells of avian myeloblastosis virus (AMV-(infected chickens were examined at various intervals post infection by immunofluorescence. AMV revertase was identified in pro- and myeloblasts; it was localized mainly in the perinuclear zone or throughout the cytoplasm. No revertase was found in erythrocytes or granulocytes. Blood cells from uninfected chickens of man contained no revertase.
Insights
Avian myeloblastosis virus (AMV) reverse transcriptase was detected in specific blood cells of infected chickens. This enzyme was absent in mature blood cells and in cells from healthy chickens.
Area of Science:
- Virology
- Cell Biology
- Immunology
Background:
- Avian myeloblastosis virus (AMV) is a retrovirus known to cause myeloblastosis in chickens.
- Understanding the expression and localization of viral proteins is crucial for studying viral pathogenesis.
Purpose of the Study:
- To investigate the presence and cellular localization of AMV reverse transcriptase in peripheral blood cells of AMV-infected chickens.
Main Methods:
- Immunofluorescence staining was employed to detect AMV revertase.
- Peripheral blood cells were collected at various time points post-infection.
Main Results:
- AMV reverse transcriptase was identified in pro- and myeloblasts.
- The enzyme was primarily localized to the perinuclear zone or throughout the cytoplasm of these cells.
- No revertase activity was detected in erythrocytes or granulocytes from infected chickens.
- Blood cells from uninfected control chickens showed no detectable revertase.
Conclusions:
- AMV reverse transcriptase expression is restricted to specific immature myeloid cell populations in infected chickens.
- The findings provide insights into the cellular tropism of AMV during infection.
