In vivo chimeric antigen receptor (CAR)-T cell therapy - Nature Reviews Drug Discovery In vivo chimeric antigen receptor (CAR)-T cell engineering uses targeted delivery systems to generate CAR-T cells directly in patients, bypassing ex vivo manufacturing. This Review examines emerging viral and lipid nanoparticle platforms, early clinical proof of concept and potential applications beyond cancer.

For readers interested in finding out more about in vivo CAR-T therapies such as those at the centre of the $1.5 billion acquisition of Orbital Therapeutics by Bristol Myers Squibb today, here's a comprehensive review

Systematic discovery of CRISPR-boosted CAR T cell immunotherapies - Nature CELLFIE, a CRISPR platform for optimizing cell-based immunotherapies, identifies gene knockouts that enhance CAR T cell efficacy using in vitro and in vivo screens.

CAR T cells showcase the enormous potential of cell therapies, but often fail due to lack of evolutionary optimization. Today in @nature.com , we use #CELLFIE to engineer cell therapies at scale and share the largest resource of CRISPR screens in CAR T cells. www.nature.com/articles/s41...
