The human body has the ability to ward off viruses by activating a naturally occurring protein at the cellular level, setting off a chain reaction that disrupts the levels of cholesterol required in cell membranes to enable viruses to enter cells. The findings, discovered by researchers in molecular microbiology and immunology at the Keck School of Medicine of USC, hold promise for the development of therapies to fight a variety of viral infections. "Previous studies have shown that our...

By Richard Harth, Science Writer: The Biodesign Institute Under the electron microscope, a coronavirus may resemble a spiny sea urchin or appear crownlike, (the shape from which this family of pathogens takes its name). Previously recognized as the second leading cause of the common cold in humans and for economically important diseases in many domesticated animals, a new disease form abruptly emerged as a major public health concern in 2002, when the SARS coronavirus (CoV) surfaced in Asia....

Structural biologists at the University of Pittsburgh School of Medicine have described the architecture of the complex of protein units that make up the coat surrounding the HIV genome and identified in it a "seam" of functional importance that previously went unrecognized. Those findings, reported today in Cell, could point the way to new treatments for blocking HIV infection. The researchers used a combination of nuclear magnetic resonance and cryoEM, which are standard structural biology...

Scientists may need to rethink the design of drugs meant to block HIV from infecting human cells, according to a study that appears in the May 1st issue of the journal Cell, a Cell Press publication. That's because the new report shows that HIV doesn't enter cells in the way that experts had generally assumed it did.Rather than fusing directly with the plasma membrane at cells' outer surfaces to release its contents, HIV fusion primarily occurs via smaller, membrane-bound compartments inside...
