Redirection of therapeutic T cells to a bone marrow niche improves their persistence and anti-tumor functions: transcription profiling by array of resting memory OT-I T_CXCR4) or OT-I T_Control cells isolated from the spleen 90 days following DC vaccination.

ABSTRACT: This study reports the improvement in function and antitumor efficacy of CXCR4 overexpression in therapeutic CD8+ T cells. Polyclonal CD8+ T cells from OT-I C57BL/6 (B6) mice were transduced with a modified pMP71 retroviral vector containing murine Cxcr4 and Gfp reporter sequences (T_CXCR4) or with a control vector containing Gfp alone (T_Control), and co-transferred into to B6 mice that were then vaccinated with peptide-pulsed DC. 90 days following DC vaccination, lymphocytes were isolated from the spleen and resting memory OT-I T_CXCR4 and OT-I T_Control cells were FACS sorted to perform gene expression profiling.
