Organ-derived dendritic cells have differential effects on alloreactive T cells.
Dendritic cells (DCs) are considered critical for the induction of graft-versus-host disease (GVHD) after bone marrow transplantation (BMT). In addition to their priming function, dendritic cells have been shown to induce organ-tropism through induction of specific homing molecules on T cells. Using adoptive transfer of CFSE-labeled cells, we first demonstrated that alloreactive T cells differe...
متن کاملCutting edge: instructive role of peripheral tissue cells in the imprinting of T cell homing receptor patterns.
Tissue-specific homing of effector and memory T cells to skin and small intestine requires the imprinting of specific combinations of adhesion molecules and chemokine receptors by dendritic cells in the draining lymph nodes. In this study, we demonstrate that CD8(+) T cells activated by Ag-pulsed bone marrow-derived dendritic cells were induced to express the small intestine homing receptors al...

متن کاملMaintenance of peripheral tolerance through controlled tissue homing of antigen-specific T cells in K14-mOVA mice.
Immunological tolerance is crucial to avoid autoimmune and inflammatory diseases; however, the mechanisms involved are incompletely understood. To study peripheral tolerance to skin-associated Ags, we generated new transgenic mice expressing a membrane-bound form of OVA in skin under the human keratin 14 (K14) promoter (K14-mOVA mice). In contrast to other transgenic mice expressing similar sel...
متن کاملLymph node stromal cells support dendritic cell-induced gut-homing of T cells.
T cells are imprinted to express tissue-specific homing receptors upon activation in tissue-draining lymph nodes, resulting in their migration to the site of Ag entry. Expression of gut-homing molecules alpha(4)beta(7) and CCR9 is induced by retinoic acid, a vitamin A metabolite produced by retinal dehydrogenases, which are specifically expressed in dendritic cells as well as stromal cells in m...
