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.

Improving quality control for CAR T cell therapies

Drug Discovery World

Finally, in 2017, after years of improving T cell engineering techniques, the first chimeric antigen receptor (CAR) T cell therapy received FDA approval. The immune system typically identifies foreign entities such as bacteria and viruses and activates lymphocytes such as T cells to destroy them with overwhelming force.
