New Structure of Key Protein Holds Clues for Better Drug Design

odies. In addition to Wthrich and Eddy, authors of the study, "Allosteric Coupling of Drug Binding and Intracellular Signaling in the A2a Adenosine Receptor," were Tatiana Didenko and Pawel Stanczak of The Scripps Research Institute; Reto Horst of The Scripps Research Institute and Pfizer Worldwide Research and Development; Zhan-Guo Gao and

Pulmonary Fibrosis Caused by Single Transcription Factor

Idiopathic pulmonary fibrosis is currently an incurable lung disease, in which sufferers lose the ability to absorb adequate oxygen. Although the word 'idiopathic' means that the cause is unknown, the disease primarily affects former and active heavy smokers from the age of 50. An important role in idiopathic pulmonary fibrosis is

Harnessing sperm to treat gynecological Diseases

Creating an effective way to target cancer cells with drugs is challenging on multiple fronts. For example, the drugs don't always travel deeply enough through tissues, and they can get diluted in body fluids or sidetracked and taken up by healthy organs. To get around these issues, scientists have turned

Hunting for Immune Cells’ Cancer Targets

The screening technology, developed by Howard Hughes Medical Institute Investigator (HHMI) Christopher Garcia and colleagues after almost 20 years of basic molecular studies of the immune system, may ultimately lead to more effective immunotherapies, which harness the body's immune system to fight cancer. "This is going to widen the scope

New Methods Reveal the Biomechanics of Blood Clotting

The extensive results are published in two separate studies, in the Proceedings of the National Academy of Sciences (PNAS) and in Nature Methods. "We show conclusively that, in order to activate clotting, the cell needs a targeted force of a magnitude of just a few piconewtons -- or a force about a billion times
