---|---|---|---|
MUC5B | 0.65 ± 0.05 | 2.1 ± 0.9 | 4.6 ± 0.9 |
Lactoferrin | >12.5 | >12.5 | |
Salivary gp-340 | 0.22 ± 7 | 0.05 ± 0.01 | 0.13 ± 0.02 |
Thrombospondin | >7.5 | ≥4.4 |
Results are mean ± SEM of three or more experiments and are expressed as μg/ml of the indicated purified proteins required to inhibit HA activity of 40 HA units of the Phil82 or PR-8 strain of influenza A virus or Sendai virus. Thrombospondin had detectable HA inhibitory activity against the PR-8 strain of IAV in three of five experiments and not in the other two (hence, ≥4.4).
