Carnegie Mellon scientists find key HIV protein makes cell membranes bend more easily

...ng this energy should help explain in part how HIV infection occurs so readily,” said Tristram-Nagle. “Our findings definitely will change how theoreticians think about virus-cell interactions. This same phenomenon could provide a general way that viruses use to infect cells, so it will be exciting to look at ...

Genomic Analysis Uncovers New Targets for HIV Vaccine

...multiple blood tests documenting viral loads after infection and before they started receiving antiretroviral treatment. The three polymorphisms were identified after all the blood samples of the selected patients were screened for more than 555,000. Additionally, the researchers discovered many other geneti...

Research identifies protein that signals flowering in squash plants

...r. Analysis of such induced plants showed that the infection zone of ZYMV was not coincident with the plant’s floral meristems, indicating that FT mRNA is unlikely to be the florigenic signal in this system. Next, heterografting studies were conducted using flowering Cucurbita maxima (pumpkin) stocks (the stoc...
