Many studies of human immunology have been limited to ex vivo analysis
due to ethical considerations. Detailed study, however, requires in vivo analysis, as ex
vivo analysis of human immune cells does not always represent in vivo status.
Therefore, small animal models have been used to overcome this limitation and several
humanized mouse models that reproduce the human immune system have been
developed. This review summarizes humanized mouse model characteristics and
progress in their use for research of human diseases immunology.
