Discovery may help design effective therapies for the genetic disease that mainly affects Ashkenazi Jews
An interdisciplinary team of Weizmann Institute scientists has solved the three-dimensional structure of an enzyme called glucocerebrosidase. Mutations occurring in this enzyme cause Gaucher disease, a genetic illness that mainly affects Ashkenazi Jews. The Institute study, published recently in EMBO Reports, may lead to the design of effective new therapies for treating the disease.
Gaucher disease was first described in 1882 by the French physician Philippe Gaucher. It is characterized by swelling and enlargement of the spleen and liver and disruption in the function of these organs, and in rare cases it also affects the brain. In the 1920s, the disease was found to be caused by the excessive accumulation of a fatty substance, or lipid, called glucosylceramide. In the 1960s, researchers discovered that the accumulation occurs due to a defect in the glucocerebrosidase enzyme, whose function is to break down this lipid and regulate its amount. In the 1980s, the gene responsible for manufacturing the enzyme was isolated; scientists found that mutations in this gene disrupt the function of the enzyme, leading to the development of Gaucher disease.

Abnormal scarring is a serious threat resulting in non-healing chronic wounds or fibrosis. Scars form when fibroblasts, a type of cell of connective tissue, reach wounded skin and deposit plugs of extracellular matrix. Until today, the question about the exact anatomical origin of these fibroblasts has not been answered. In order to find potential ways of influencing the scarring process, the team of Dr. Yuval Rinkevich, Group Leader for Regenerative Biology at the Institute of Lung Biology and Disease at Helmholtz Zentrum München, aimed to finally find an answer. As it was already known that all scars derive from a fibroblast lineage expressing the Engrailed-1 gene - a lineage not only present in skin, but also in fascia - the researchers intentionally tried to understand whether or not fascia might be the origin of fibroblasts.

Conventional light microscopes cannot distinguish structures when they are separated by a distance smaller than, roughly, the wavelength of light. Superresolution microscopy, developed since the 1980s, lifts this limitation, using fluorescent moieties. Scientists at the Max Planck Institute for Polymer Research have now discovered that graphene nano-molecules can be used to improve this microscopy technique. These graphene nano-molecules offer a number of substantial advantages over the materials previously used, making superresolution microscopy even more versatile.
Microscopy is an important investigation method, in physics, biology, medicine, and many other sciences. However, it has one disadvantage: its resolution is...
