Lakdawala, S.S. et al., Nature 526, 122–125 (01 October 2015) doi:10.1038/nature15379 http://www.ncbi.nlm.nih.gov/pubmed/26416728 The epidemiological success of flu viruses relies on successful airborne transmission from person to person. But the viral properties governing the airborne transmission of flu viruses are complex. A new study reveals that the soft palate at the back of the roof of the mouth plays a key role in the flu viruses’ ability to transmit through air. Previous research had shown that airborne transmissibility is dependent on the viral surface hemagluttinin (HA) glycoprotein’s ability to bind to receptors on human respiratory cells. Some viral strains bind better to alfa 2
