WebBoth types can be expanded simultaneously, but differences in the ratio in the final product could affect clinical outcomes. In vivo experiments demonstrated that the optimal product composition to start a CAR T cell expansion is a 1:1 ratio of CD4 + naïve to CD8 + central memory T cells (Sommermeyer et al. 2016). The CD4 /CD8 ratio is the ratio of T helper cells (with the surface marker CD4) to cytotoxic T cells (with the surface marker CD8). Both CD4 and CD8 T cells contain several subsets. The CD4 /CD8 ratio in the peripheral blood of healthy adults and mice is about 2:1, and an altered ratio can indicate diseases relating to immunodeficiency or autoimmunity.
