  • Publication number: 20250002854
    Abstract: Methods of generating populations of tumour-infiltrating T cells The present invention provides a method of generating a population of tumour-infiltrating T cells, said method comprising administering to a subject a positively charged amphipathic amino acid derivative, peptide or peptidomimetic which is able to lyse tumour cell membranes and then collecting a cellular sample from a tumour within said subject and separating T cells therefrom. The present invention further provides a method of generating a population of tumour-infiltrating T cells, said method comprising separating T cells from a cellular tumour sample taken from a subject treated with a positively charged amphipathic amino acid derivative, peptide or peptidomimetic which is able to lyse tumour cell membranes and optionally culturing said T cells.
