Because no biomarkers exist for Alzheimer’s disease, preclinical diagnosis is impossible and assessment of therapies that could prevent or reverse the course of the disease is inhibited. By combining mouse models, multiphoton microscopy, and unique imaging agents, researchers at Massachusetts General Hospital in Boston are providing important information about the mechanisms of this progressive neurodegenerative disease and techniques to test new drugs more quickly. Their work also provides a springboard for developing new approaches to image the disease in humans.

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.

Receiving an R01 grant can literally change a researcher’s life, but getting that first grant can be a daunting task. To ease the process, NIBIB has implemented a new investigator funding policy. Follow three investigators with unique stories who have successfully earned grants under the new policy and whose work is moving biomedical research forward.
