Diffuse large B-cell lymphoma (DLBCL) is a heterogeneous disease group with CAR T cells offering therapeutic success in otherwise hard-to-treat cases. Here, authors study the in vivo expansion and persistence of CAR T cells in the peripheral blood of successfully treated DLBCL patients, demonstrating that two different CD8+ precursor phenotypes in the initial cell product give rise to two independent waves of clonally expanded CAR T cells with distinct phenotypes in peripheral blood.
