A new study from scientists at The Scripps Research Institute (TSRI) show that two avian influenza strains recently seen in human infections in Asia, do not have the ability to easily infect humans.
TSRI researchers have analyzed a key protein from two influenza strains that recently began causing sporadic infections among people in China and Taiwan.
Yet the studies also highlight the versatility that bird flu viruses apparently have in attaching to host cells.
“These bird flu viruses seem able to bind to receptors on host cells in different ways and thus can probably mutate in different ways to jump to humans—so we shouldn’t be complacent about our ability to predict the viral changes required to get a pandemic,” said Ian A. Wilson, Hansen Professor of Structural Biology and chair of TSRI’s Department of Integrative Structural and Computational Biology.

The new research, from Wilson’s laboratory and the laboratory of James C. Paulson, acting president and CEO of TSRI, is reported in two papers in the journal Cell Host & Microbe on March 11, 2015.
