Abstract Surfactant protein A (SP-A) inhibits hemagglutination (HA) activity and infectivity of influenza A viruses (IAV). As we have showed before in different assays, SP-A2 gene products are more active than SP-A1. Here, we hypothesized that SP-A1 and SP-A2 mammalian CHO-cell-expressed proteins also differentially modulate HA inhibition of IAV. We found that both SP-A1 and SP-A2 equally displayed α(2,3)-linked sialic acids, and had similar activity against a strain (PR-8) that preferentially binds to α(2,3)-linked sialic acids. Based on these findings, we speculate that in human lung SP-A1 and SP-A2 will not be different in their activity against IAV that preferably bind to α(2,3)-linked sialic acids (like avian strains).
