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.

The evolution of assays for immuno-oncology research

Drug Discovery World

The first such research dates back to 1891, when William Coley attempted to inject heat-inactivated bacteria to treat osteosarcoma. Genetically engineered mouse models (GEMM) recapitulate the stromal biology of different human cancers including the tumour microenvironment that regulates the disease process. Front Immunol.
