UBC maps B.C. teen's H5N1 mutations and finds they weakened human-cell binding
Cryo-electron microscopy of Canada's first locally acquired human bird-flu case shows two surface-protein changes reduced receptor latching, challenging early fears the virus was adapting toward people.

The Vancouver Sun reported Subramaniam's working hypothesis that the virus may have bypassed upper-airway sugar receptors and reached deeper airways, though that pathway has not been proven. B.C. Centre for Disease Control sequencing of the patient's samples enabled the lab follow-up. Researchers stress genetic surveillance alone cannot show what mutations do in practice, and other changes in the same region could behave differently. The work was supported by a Canada Biomedical Research Fund grant through the PROGENITER platform.
