...that sickened people across the country and worried many more left its mark on Harvard during the past year. Harvard University Health Services (UHS) officials began preparing for the potential outbreak before a single case had been diagnosed on campus. After popping up in local schools, the virus first made its Harvard debut at Harvard Dental School, which closed temporarily after detecting its first case. At the end of last school year, UHS refrained from testing patients for H1N1 unless they were at risk for complications, but suggested that the Harvard community forgo...
...colloquially known as swine flu had bounced to almost every corner of the world in April, health officials were girding for a once-in-a-lifetime pandemic with the potential to kill millions. H1N1 ripped through the U.S., prompting President Obama to declare a national emergency. But while the virus has been formidable--some 50 million Americans have been sickened since April, according to Centers for Disease Control and Prevention estimates, and about 10,000 have died--it hasn't been the seismic event some feared. At least...
Further research revealed that the same proteins also help cells resist illnesses such as West Nile virus, dengue fever, and yellow fever. But the proteins did not seem to be effective in defending cells from HIV or hepatitis...
...which the study took place. With this understanding, Elledge and his team systematically deactivated every gene in the human genome—testing some 20,000 different genes—using new RNA interference technology, hoping to determine the genes in the host cells that the virus relied upon for infection...
...researchers, who had already used this same process in studies of HIV and the hepatitis C virus, hoped to find that some of the treated cells could not be infected with the influenza virus, which would suggest that the virus needed the deactivated gene to function. Instead, the researchers were surprised to find that the rate of infection increased dramatically when certain genes were deactivated...
