Mayo researchers discover HIV dependence on a human protein

...permanently integrated viruses in long-lived cells prevent elimination of HIV. In the future, it will be of interest to examine whether HIV's dependence on p75 can be exploited therapeutically." How They Did It The researchers started by noticing that p75 "tethers" HIV integrase to human chromosomes like...

Transmission of antibiotic-resistant bacteria linked to previous intensive care unit room occupants

...guidelines, indicating that such guidelines do not prevent transmission of disease-causing bacteria. However, the low overall risk among patients exposed to the bacteria "suggests that levels of contamination do not pose a high risk for transmission or that current cleaning methods generally reduce contamin...

From a lowly yeast, researchers divine a clue to human disease

...op signs near the beginning of some genes normally prevent RNA polymerase II from making RNA from those genes. Sen1 mutations, on the other hand, allow access to these messages, triggering genes that normally aren't operational. These garbled genetic messages -- whether with too much or too little genetic...

HIV gets a makeover

...-1 uses a protein called Vif to destroy APOBEC and prevent the attack. Monkey APOBEC proteins, however, aren't susceptible to the human virus's Vif. So Hatziioannou did another swap -- the SIV Vif gene for the HIV one -- and then another round of forced adaptation to create viruses that would multiply with v...

T for two: Scientists show how immune system chooses best way to fight infection
