LGALS9 and influenza: Hattori et al. reported that Gal-9 exhibited anti-influenza function via directly binding to IAVs including A/Puerto Rico/8/34 (H1N1), A/Aichi/2/68 (H3N2), and A/Hong Kong/483/97 (H5N1), further blocking the virus from interacting with the sialic acids receptors on the host cells [51].
