Beschreibung
Zusammenfassung:	Un ratón Rag-/-, γc-/-, Flk2-/- deficiente para el gen activador de recombinación 2 (Rag2) y/o el gen activador de recombinación 1 (Rag1), cadena gamma del receptor de interleuquina-2 (γc) y quinasa de hígado fetal 2 (Flk2) que comprende una alteración en el(los) gen(es) Rag1 y/o Rag2, en el gen γc y el gen Flk2, (i) con células progenitoras hematopoyéticas humanas injertadas, y (ii) al que se administra ligando de la quinasa de hígado fetal 2 humano exógeno (Flk2L). The present invention relates to a transgenic animal model system based on the development of transgenic mice bearing components of the human immune system. Specifically, the invention relates to a Flk2 deficient Rag−/−γc−/− transgenic mouse and the engraftment of said mouse with human hematopoietic stem cells. The present invention further provides methods for increasing the numbers of functionally competent human dendritic cells and the hematopoietic targets cells that they interact with in said transgenic mouse through the administration of Flk2L. The transgenic animal model system of the invention may be used for testing human vaccine candidates, for screening potential immune adjuvants and for developing novel therapeutics.
