To determine whether influenza virus neuraminidase plays a role in facilitating viral entry and the initiation of infection in human airway epithelial cells.
Infected cultures of human airway epithelium with human and avian influenza viruses.
Treated viral cultures with the neuraminidase inhibitor oseltamivir carboxylate compared against untreated control cultures.
Quantified the number of infected epithelial cells at 7 hours after viral inoculation.
Treated cultures demonstrated a 20- to 500-fold reduction in infected cells compared with untreated cultures at 7 hours post-inoculation (P < 0.0001).
Oseltamivir carboxylate treatment suppressed the initiation of influenza infection, confirming that neuraminidase functions during early viral entry.

Implication

Experimental study demonstrates that neuraminidase inhibition reduces influenza infection initiation in human airway epithelium, supporting prophylactic neuraminidase inhibitor use.
