abstract = {Cancer treatment with adoptively transferred
tumor-associated antigen-specific CD4+ T-helper cells is a
promising immunotherapeutic approach. In the pancreatic
cancer model RIP-Tag2, the intraperitoneal (i.p.)
application of Tag-specific TH1 cells exhibited a profound
antitumoral efficiency. We investigated, whether an
intravenous (i.v.) application of Tag-TH1 cells induces an
equivalent therapeutic effect. Adoptively transferred
fluorescent Tag-TH1 cells revealed a pronounced homing to
the tumors after either i.p. or i.v. transfer, and both
routes induced an almost equivalent therapeutic effect as
demonstrated by magnetic resonance imaging, blood glucose
level course and histology. The i.v. administration of
Tag-TH1 cells induced p16INK4-positive/Ki67-negative tumor
senescence more efficiently than i.p. administration. Both
routes replenish host CD4+ T cells by transferred T cells
and recruitment of B and dendritic cells to the tumors while
reducing CD8+ T cells and depleting macrophages. Both
administration routes efficiently induced a similar
antitumoral efficiency despite the pronounced senescence
induction after i.v. administration. Thus, a combinatory
i.v./i.p. injection of therapeutic cells might overcome
limitations of the individual routes and improve therapeutic
efficacy in solid tumors.},
