Scientists engineer safe, virus-resistant E coli for research

Drug Discovery World

In a step forward for genetic engineering and synthetic biology, US researchers have modified E coli bacteria to be immune to infection by all natural viruses tested so far. The team used two safeguard methods to prevent the bacteria and their modified genes from escaping into the wild.

Scientists discover small RNA that regulates bacterial infection

The Pharma Data

Scientists discover small RNA that regulates bacterial infection People with weakened immune systems are at constant risk of infection. But the bacteria can sometimes change their behavior and enter the bloodstream, causing chronic localized infections to become acute and potentially fatal. aeruginosa infections.

Gene-editing produces tenfold increase in superbug slaying antibiotics

Scienmag

Martins Scientists have used gene-editing advances to achieve a tenfold increase in the production of super-bug targeting formicamycin antibiotics. The John Innes Centre researchers used the technology to create a new strain of Streptomyces formicae bacteria which over-produces the medically promising molecules.

Exa-Cel CRISPR Gene Therapy for Sickle Cell Disease Deemed Safe by FDA Advisory Panel

XTalks

After spending almost an entire day deliberating the safety of Vertex Pharmaceuticals’ and CRISPR Therapeutics’ CRISPR-based gene therapy exa-cel for sickle cell disease, a US Food and Drug Administration (FDA) advisory panel appears to be satisfied with what it saw. CRISPR works as genetic scissors to edit parts of the genome.
