Bacteria that cause two common ailments, traveler’s diarrhea and the sexually transmitted disease gonorrhea, grab hold of humans because of tiny anchors, or pili, on the bacteria’s surface. A University of Virginia researcher has developed a novel approach to imaging these flexible filaments. Understanding the pili’s structure may help other researchers develop new vaccines to treat highly infectious diseases.

Researchers from the University of North Carolina, Chapel Hill, have developed a suite of imaging tools that enable investigators to visualize and manipulate living cells, molecules, and strands of DNA with unprecedented control. The imaging systems are providing new insights into how blood clots form and how the lungs clear mucus.

Ultrasound creates temporary gaps in cell membranes. These gaps are large enough to allow macromolecules to enter, thus offering the potential to use this noninvasive technology to deliver drugs and genes to specific organs and tissues within the body. Understanding the mechanism by which ultrasound creates these gaps is bringing researchers one step closer to using this technology for targeted drug and gene delivery.
