And to make use of this, the researchers added a sequence of short interfering RNA that silences the genes responsible for producing the HLA class 1 protein. And along with this genetic tweak, they introduced the CARG-GSL in another gene that encodes either PD-L1 or a single chain protein, both which help strengthen the NK cell's cancer-fighting ability. This is repeater station kilo-kilo-7. And the last little bit of this is that all the internet components are combined into a single DNA framework which allows the team to convert donor NK cells into a mutavasive CARN-K cell. And using this method, the engineered cells target a protein commonly found in malignant B cells in the form of patients.
