CRISPR opens door to new type of medicine - genome surgery

29.10.2018   |   Press monitoring

Within a few years, Jim Johnsen and Delaney Van Riper may be among the first to benefit from CRISPR-Cas9 gene editing, a breakthrough that has already revolutionized biology research and promises to resurrect gene therapy. UC San Francisco doctors working closely with UC Berkeley scientists plan to edit their genomes to correct rare genetic...

Cellular dust provides new hope for regenerative medicine

26.10.2018   |   Press monitoring

While stem cells have the most therapeutic potential, the benefits of regenerative medicine may best be mobilised using extracellular vesicles (EVs), also known in the past as "cellular dust." A team of researchers from CNRS, AP-HP, INSERM and Paris Descartes and Paris Diderot Universities have tested these vesicles for the first time in a...

Vaccinating humans to protect mosquitoes from malaria

24.10.2018   |   Press monitoring

For decades, scientists have been trying to develop a vaccine that prevents mosquitoes from spreading malaria among humans. This unique approach – in which immunized humans transfer anti-malarial proteins to mosquitoes when bitten – is called a transmission-blocking vaccine (TBV). A few malarial TBVs have shown promise but they have not been...

Smallest life forms have smallest working CRISPR system

22.10.2018   |   Press monitoring

An ancient group of microbes that contains some of the smallest life forms on Earth also has the smallest CRISPR gene-editing machinery discovered to date. The peewee protein machinery, dubbed Cas14, is related to but one-third the size of the Cas9 protein, the business end of the revolutionary gene-editing tool CRISPR-Cas9. While Cas9 was...

Engineered enzyme eliminates nicotine addiction in preclinical tests

19.10.2018   |   Press monitoring

Scientists at Scripps Research have successfully tested a potential new smoking-cessation treatment in rodents. In a study published online in Science Advances on Oct. 17, 2018, the scientists gave nicotine-dependent rats an engineered enzyme that breaks down nicotine in the bloodstream before it can reach the brain. Treatment quickly reduced the...

Protein derived from cottonseed for human nutrition one step closer to reality

17.10.2018   |   Press monitoring

Cottonseed ground into flour to deliver protein to millions of people, a project to which Dr. Keerti Rathore has devoted more than half his professional career, is one step closer to reality. Through a project funded by Cotton Incorporated, Rathore and the Texas A&M team have developed a transgenic cotton plant – TAM66274 – with ultra-low...

Nanoparticles to treat snakebites

15.10.2018   |   Press monitoring

Venomous snakebites affect 2.5 million people, and annually cause more than 100,000 deaths and leave 400,000 individuals with permanent physical and psychological trauma each year. Researchers reporting in PLOS Neglected Tropical Diseases have now described a new approach to treating snake bites, using nanoparticles to bind to venom toxins and...

Human retinas grown in a dish explain how color vision develops

12.10.2018   |   Press monitoring

Biologists at Johns Hopkins University grew human retinas from scratch to determine how cells that allow people to see in color are made. The work, set for publication in the journal Science, lays the foundation to develop therapies for eye diseases such as color blindness and macular degeneration. It also establishes lab-created "organoids" as...

Adult heart attack risk can be predicted in childhood with new cheap genetic test

10.10.2018   |   Press monitoring

The current way doctors evaluate a patient's risk for coronary heart disease involves monitoring one's blood pressure and cholesterol while also identifying other factors such as smoking, family history or diabetes. The problem with this strategy is that it is age-dependent, with monitoring only beginning when a person reaches the age of 40 or...

Bionic algae barrel through blood to deliver drugs

8.10.2018   |   Press monitoring

Swimming algae have been enlisted to carry drugs to individual cells, raising the prospect that such ‘microswimmers’ could deliver targeted therapies. Miniscule devices propelled by living organisms can ‘swim’ through the body to deliver cargo such as doses of drugs. A variety of organisms have been joined with artificial structures to treat some...
