Abstract:
Literature pertaining to the interactions between Marek's disease virus (MDV) entry-related glycoproteins and corresponding receptors is still limited. Results from a Western blot analysis of cellular proteins for virus receptors and co-immunoprecipitation suggest that heat shock protein 70 (HSP70) is a potential cellular receptor for MDV glycoprotein gH. Plaque inhibition assays confirm the involvement of HSP70 in the early stages of MDV entry into chicken embryo fibroblasts (CEF). The present work supports that HSP70 is implicated in the MDV entry process by binding to gH, and enhances the understanding of multifunctional HSP70 and the MDV infection process.
Insights
Heat shock protein 70 (HSP70) acts as a cellular receptor for Marek's disease virus (MDV) glycoprotein gH. This interaction is crucial for early-stage MDV entry into chicken cells, advancing our understanding of viral infection.
Area of Science:
- Virology
- Cell Biology
- Immunology
Background:
- Interactions between Marek's disease virus (MDV) entry glycoproteins and cellular receptors are not well understood.
- Limited literature exists on the specific receptors involved in MDV entry.
Purpose of the Study:
- To identify the cellular receptor for the MDV glycoprotein gH.
- To elucidate the role of this receptor in the early stages of MDV infection.
Main Methods:
- Western blot analysis to identify potential cellular receptors.
- Co-immunoprecipitation assays to confirm protein interactions.
- Plaque inhibition assays to assess viral entry into chicken embryo fibroblasts (CEF).
Main Results:
- Heat shock protein 70 (HSP70) was identified as a potential cellular receptor binding to MDV glycoprotein gH.
- HSP70 was confirmed to be involved in the early stages of MDV entry into CEF.
- This binding interaction facilitates the MDV infection process.
Conclusions:
- HSP70 plays a significant role as a cellular receptor in MDV entry by interacting with gH.
- This finding enhances the understanding of both HSP70's functions and the MDV infection mechanism.
