description

Humanized mice represent a suitable preclinical test system for example therapeutic interventions in various disease settings, including infections. Here, we intended to establish such system for cutaneous leishmaniasis by infecting T, B and NK cell-deficient mice adoptively transferred with human peripheral blood mononuclear cells (PBMC). L major infection led to the establishment of parasite lesions harbouring viable parasites and human T cells, but parasite elimination was not seen due to a species-specific activity of T cell-derived human IFNγ. In addition, up to 50% of infected mice succumbed to severe graft-versus-host disease. In summary, even though long-term disease outcome assessments are impossible, this model of humanized mice can be used for studying lesion development and generation of oligoclonal anti-parasite human T cell responses in vivo.
