Glycomics and Proteomics Approaches to Investigate Early Adenovirus-Host Cell Interactions

Area of Science:

• Virology
• Glycobiology
• Proteomics

Background:

• Adenoviruses, a large family of viruses, utilize specific glycan and protein interactions to infect host cells.
• Diverse human adenovirus types exhibit varied tropism due to differences in attachment factors and receptor usage.
• Understanding these interactions is key to deciphering viral entry mechanisms.

Purpose of the Study:

• To review known adenovirus interactions with glycan and protein receptors.
• To explore glycomics and proteomics strategies for identifying novel virus receptors and attachment factors.
• To discuss implications for viral tropism and antiviral drug development.

Main Methods:

• Review of existing literature on adenovirus-receptor interactions.
• Discussion of advancements in mass spectrometry for glycan and peptide identification.
• Highlighting developments in glycan microarray technologies for high-throughput screening.

Main Results:

• Adenovirus attachment and entry are mediated by specific glycan and protein interactions.
• High-throughput analytical techniques enable systematic identification of these interactions.
• Mapping these interactions provides insights into viral tropism and host range.

Conclusions:

• Advanced glycomics and proteomics are essential for identifying elusive adenovirus receptors.
• Understanding virus-host interactions is critical for developing targeted antiviral therapies.
• Future research should focus on overcoming challenges in studying non-enveloped virus entry.
