| Research Abstract |
Humanized mice, in which human hematopoietic and immune systems are reconstituted in severe immunodeficient NOG mice by transplanting human hematopoietic stem cells, have a lot of attention. In the humanized mouse, humoral immune responses against exogenous substances are generally weak. IgG responses, especially, have been difficult to induce. To improve the immune systems, we established a novel mouse strain which expresses human HLA class II genes. We found that the HLA-DR4 expressing NOG mice could produce antigen specific human IgG responses, when they were transplanted with HSC from HLA-haplotype identical donors. This model will be useful to study human immune responses and in developing various therapeutic drugs.
