LONDON – Oxford University spinout Oxdx Ltd. has raised £2.6 million (US$3.6 million) in pre-seed funding to advance development of a technology for directly identifying infectious pathogens without the need to purify, culture or amplify samples first. The instant testing method uses a mixture of a single universal reagent, high resolution microscopy and machine learning, to identify specific species and strains of bacteria, viruses and other pathogens within minutes.

Researchers at Inserm have developed a method to direct pre-existing antibodies toward new targets. Their bimodular fusion proteins could be a broadly useful method for expanding access to antibody therapy. In a study that appeared in the Feb. 11, 2022, issue of Science Advances, the teams showed that antibodies to Epstein-Barr virus (EBV), which are present in 95% of the global population, could be redirected to a target cell of their choosing by fusing an EBV antigen to a cellular targeting ligand.
