Leonard Shultz

Leonard Shultz is a Professor at the University of Maine Graduate School of Biomedical Science and Engineering. His research focuses on the development and application of humanized SCID mice for translational biomedical research, particularly in immunodeficiency diseases, autoimmunity, and hematological disorders. He has pioneered mouse models like the NOD/SCID/IL2rγ null strain to study human immune system development and disease mechanisms.

• Education: PhD in Immunology from the University of Massachusetts (1972).

Shultz’s work leverages genetically engineered mouse models to investigate diabetes, bone development, anemia, thrombocytopenia, infectious diseases, and transplantation tolerance. His research has significant implications for regenerative medicine and preclinical testing of therapies.

In 2010, he identified the Abcg5 gene mutation in the trac mouse model, linking elevated plant sterols to thrombocytopenia and cardiomyopathy, mirroring human Mediterranean Macrothrombocytopenia. This discovery established a critical single-gene model for studying sterol-related hematological and cardiovascular pathologies.

His publications from 2008–2011 highlight interdisciplinary applications of humanized mice in leukemia stem cell research, HIV-1 gene editing, dengue virus studies, and solid tumor xenografts. Collaborations span institutions like the University of Massachusetts Medical School and Riken Research Center for Allergy and Immunology.
