The cell receptors that facilitate adenovirus internalization into
cells have been identified; however, the infectious pathway of virus
entry has not been established. Adenovirus entry and infection were
examined in HeLa cells lacking or overexpressing mutant dynamin, a
protein that specifically regulates clathrin-mediated endocytosis.
Expression of mutant dynamin significantly reduced adenovirus
internalization and gene delivery, indicating a functional requirement
for this molecule. These findings are consistent with virus entry via
the clathrin-coated pit pathway.
