Process for producing a composition of engineered T cells

Abstract

The present disclosure provides methods for genetically engineering T cells, such as CD4+ T cells and/or CD8+ T cells, for use in cell therapy. In some aspects, the provided methods include one or more steps for pooling enriched CD4+ and CD8+ cells, such as at a 1:1 ratio, and then incubating the cells under stimulating conditions, introducing a recombinant polypeptide to the cells through transduction or transfection, and/or cultivating the cells under conditions that promote proliferation and/or expansion. In some aspects, the provided methods are an efficient, reliable means to produce genetically engineered T cells with a high degree of success.
