Mouse model with human immune system

摘要

The present invention provides a non-human genetically immunodeficient mammal the peripheral blood of which contains a non-lethal percent of T-cells of human origin which is at least 20% as well as a non-human genetically immunodeficient mammal having a lethal percent of T-cells of human origin in the peripheral blood which is at least 60%. Also provided is a method of screening a substance for anti-HIV activity comprising obtaining a non-human genetically immunodeficient mammal having a lethal percent of human T-cells in the peripheral blood which is at least 60%; infecting the mammal with an amount of HIV sufficient to rescue the mammal from death from the effects of the lethal percent of human T-cells; administering the substance to the mammal; and determining if the substance kills the mammal by inhibiting the rescue of the mammal by HIV, the death of the mammal indicating a substance having anti-HIV activity.
