Abstract: The present disclosure relates to a JAK3 gene-mutated severe combined immunodeficiency animal model and a method of constructing the same. In the JAK3 gene-mutated severe combined immunodeficiency animal model of the present disclosure, the JAK3 gene is specifically deficient, the expression of cytokines is regulated by controlling the number and activity of macrophages, and the thymus, lymphocytes, and Peyer's patches, which are observed in conventional severe combined immunodeficiency animal models, particularly mini-pigs, are completely lacking. In addition, the animal model of the present disclosure can be used as a treatment model for JAK3 SCID patients, as similar phenotypes are observed in patients with human severe combined immunodeficiency caused by a JAK3 gene mutation, and can be used for artificial blood development or xenotransplantation.
