Similarly, ROR1RCD28+ and ROR1RCD137+ T cells generated from PBMC of a patient with CLL were able to lyse EL4-ROR1 and autologous tumor cells (ROR1+; isolated with CD19-specific magnetic beads), while autologous T cells and parental EL4 (both ROR1neg) cells were spared (Fig 5c). The gene discussed is ROR1; the disease is neoplasm.
