New approach to prevent bacterial infections from taking hold

Dr Quinn Parks and colleagues describe how they used enzymes against products of the body's own defence cells to prevent Pseudomonas aeruginosa bacteria from building a protective biofilm which enables them to avoid both the body's immune mechanisms and antibiotics.

Cells get two chances, not just one, to fix their mistakes

Cells have two chances to fix the same mistake in their protein-making process instead of just one - a so-called proofreading step - that had previously been identified, according to new research.

Experimental microbicide containing natural compound provides protection in monkeys against simian version of HIV

An experimental microbicide containing a naturally occurring compound provides protection in monkeys against the simian version of HIV by diminishing immune responses to the virus, according to a study published Wednesday in the journal Nature, the Los Angeles Times reports.

New protein identified in bacterial arsenal

Nearly a billion years ago, bacteria evolved an insidious means of infecting their hosts - a syringe-like mechanism able to inject cells with stealthy hijacker molecules. These molecules, called virulence factors, play a sophisticated game of mimicry, imitating many of the cells' normal activities but ultimately co-opting them to serve the bacteria's needs.

Researchers block immune cell rush behind deadly sepsis

Researchers have found a way to block the ability of white blood cells to sprint toward the sites of infection when such speed worsens the damage done by sepsis, the often fatal, whole-body bacterial infection, according to a study published today in the journal Blood.
