Retractable Protein Nanoneedles The ability to control the transfer of molecules through cellular membranes is an important function in synthetic biology; a new study from researchers at Harvard’s Wyss Institute for Biologically Inspired Engineering and Harvard Medical School (HMS) introduces a novel mechanical method for controlling release of molecules inside cells.Advancing Synthetic Biology Living systems rely on a dizzying variety of chemical reactions essential to development and survival. Most of these involve a specialized class of protein molecules — the enzymes.Insights into the Function of the Main Class of Drug Targets About thirty percent of all medical drugs such as beta-blockers or antidepressants interact with certain types of cell surface proteins called G protein coupled receptors.Honey’s Potential to Save Lives The healing powers of honey have been known for thousands of years. Muscles on-a-Chip This study may help explain why stem cell-based therapies have so far shown limited benefits for heart attack patients in clinical trials.3-D Printed Lifelike Liver Tissue for Drug Screening A team led by engineers at the University of California, San Diego has 3D-printed a tissue that closely mimics the human liver's sophisticated structure and function. The new model could be used for patient-specific drug screening and disease modeling. Envigo Rat Models Proven to be Susceptible to Intra-Vaginal HSV-2 Infection and Protectable Scientific findings establish the effectiveness of new approach to investigate the protective effects of vaccine candidates and anti-viral microbodies and to study asymptomatic primary genital HSV-2 infection.Valvena, GSK Sign New R&D Collaboration Valneva to supply process development services for EB66® -based Influenza vaccines. Food Triggers Creation of Regulatory T Cells IBS researchers document how normal diet establishes immune tolerance conditions in the small intestine.Counting Cancer-busting Oxygen Molecules Researchers from the Centre for Nanoscale BioPhotonics (CNBP), an Australian Research Centre of Excellence, have shown that nanoparticles used in combination with X-rays, are a viable method for killing cancer cells deep within the living body.
