Methods are provided for suppressing the immune system response in recipients of transplanted organs, tissues or cells. An extracorporeal quantity of blood from the intended transplant recipient is treated to induce monocytes contained in the blood to differentiate and form dendritic cells. The maturation of the dendritic cells is truncated at a stage where the dendritic cells can inactivate T cell clones which would otherwise generate an undesired immune system response. The immature dendritic cells can be directly administered to the transplant recipient, or the dendritic cells can be co- incubated with the bone marrow or stem cell preparation, prior to transplantation, in order to suppress or eliminate anti-recipient donor T cells contaminating the bone marrow or stem cell preparation. The methods can be used to suppress graft versus host disease in recipients of transplanted bone marrow or stem cells, or to suppress rejection of transplanted organs or tissue.

L'invention concerne des procédés de suppression de la réponse du système immunitaire chez des receveurs d'organes, de tissus ou de cellules greffés. Une quantité extracorporelle de sang du receveur du greffon est traitée afin d'induire les monocytes contenus dans le sang à se distinguer et à former des cellules dendritiques. La maturation des cellules dendritiques est tronquée à un niveau où les cellules dendritiques peuvent inactiver des clones de cellules T qui peuvent, en outre, générer une réponse du système immunitaire non souhaitée. Les cellules dendritiques immatures peuvent être directement administrées au receveur du greffon, ou les cellules dendritiques peuvent être co-incubées avec la préparation de la moelle osseuse ou de la cellule souche, avant la transplantation, afin de supprimer ou d'éliminer les cellules T de donneurs qui réagissent contre le receveur et qui contaminent la préparation de la moelle osseuse ou des cellules souches. Ces procédés peuvent être utilisés pour supprimer la réaction du greffon contre l'hôte chez des receveurs de moelle osseuse ou de cellules souches greffées ou pour supprimer le rejet d'organes ou de tissus greffés.
