    FLT3L-Induced Virtual Memory CD8 T Cells Engage the Immune System against Tumors

    Albumin-conjugated FLT3L (Alb-FLT3L) was generated and used to treat naïve C57BL/6 and OT1 mice for CD8 T cell response analysis. Syngeneic B16ova and E.G7ova mouse models were employed for adoptive cell transfer to evaluate the effects of Alb-FLT3L preconditioning of CD8 T cells on tumor progression.
