A Spanish team announced the successful development of a new mouse model of the immune system.

The researchers at the Josep Carreras Leukaemia Research Institute have bred new humanised mice, whose immune systems have been generated using mononuclear cells from cord blood.

The use of ‘humanised’ mice has aided the study of the interaction between various cancers and the immune system, and boosted development of cancer immunotherapies.

However, previous methods for generating humanised mice were either too slow or often led to severe graft-versus-host disease. The resulting humanised mice also had an imbalance in the representation of myeloid versus lymphoid immune cells.

Reporting in the Journal for Immunotherapy of Cancer, the scientist say their new method, using cord-blood cells and a new type of immunodeficient mouse, has limited graft-versus-host-disease, and has sustained a balanced representation of all immune cell types.
