Host Cell Surface Receptor for Viral Entry (None)

Target: None
Molecular classification: Receptor, Protein, Proteoglycan, Heparan Sulfate Proteoglycan (HSPG), Cell Surface Protein

Overview

Host cell surface receptors are molecules on the cell membrane that mediate viral attachment and entry. They include heparan sulfate proteoglycans (HSPGs) and other serotype-specific proteins. These receptors determine viral tropism and are exploited by gene therapy vectors like rAAVs for targeted gene delivery via endocytosis or membrane fusion.
