abstract = {While the primary purpose of radiotherapy (RT) is the
elimination of cancer cells by inducing DNA-damage,
considerable evidence emerges that anti-neoplastic effects
extend beyond mere tumor cell killing. These secondary
effects are based on activation of dendritic cells (DCs) via
induction of antitumoral immune reactions. However, there is
an ongoing debate whether or not irradiation of the DCs
themselves may negatively affect their maturation and
functionality. Human monocytes were irradiated with
different absorbed doses (1 × 15 Gy relative biological
effectiveness (RBE), 5 × 2 Gy (RBE), 1 × 0.5 Gy (RBE))
with photons, protons and carbon ions. Differentiation and
maturation of DCs were assessed by staining of corresponding
cell surface molecules and functional analysis of irradiated
DCs was based on in vitro analysis of phagocytosis,
migration and IL-12 secretion. Irradiation of CD14-positive
DCs did not alter surface phenotypes of immature DCs and
mature DCs. Not only differentiation, but also functionality
of immature DCs regarding phagocytosis, migration and IL-12
secretion capacity was not negatively influenced through RT
with photons, protons or carbon ions as well as with
different dose levels. After proton irradiation migratory
capacity of immature DCs was increased. Our experiments
reveal that phenotypic maturation of DCs remains unchanged
after RT with different fractionations and after irradiation
with particle therapy. Unaffected functionality
(phagocytosis, migration and cytokine secretion) after RT of
DCs indicated possible persistent potential for inducing
adaptive immune response. Additional effects on the
immunogenic potential of DCs will be investigated by further
functional assays.},
