Flu Viruses Use Different Keys to Enter Cells

Scientists at the University of Vermont have uncovered a major flu breakthrough: H1N1 and H3N2 strains use completely different pathways to infect lung cells, shattering the old assumption that all flu viruses rely on sialic acid. The study reveals that H3N2 depends on a specific protein, Rab11B, to enter cells — without it, the virus can’t infect even if sialic acid is present. H1N1, however, doesn’t need Rab11B. This discovery could revolutionize flu drug development by targeting unique viral entry mechanisms instead of the ubiquitous sialic acid. Experts and public health officials alike are calling it a game-changer, especially as flu continues to wreak havoc — Vermont alone saw 83 outbreaks last year — making smarter treatments more urgent than ever.
