The Need

The urgent need to address lymphoproliferative disorders, including B cell malignancies such as acute lymphoblastic leukemia (ALL) and high-grade lymphomas, drives the demand for innovative and effective therapeutic approaches. These aggressive diseases, characterized by the uncontrolled proliferation of B cells, pose significant challenges for patients and healthcare professionals. Developing reliable and predictive animal models to screen and identify potential therapeutic agents is crucial to advance the understanding and treatment of these life-threatening conditions.

The Technology

The technology offered by this invention revolves around the use of transgenic mice carrying a miR155 gene, specifically targeted to B cells using an Ig heavy chain-Eμ enhancer. These mice undergo a preleukemic pre-B cell proliferation, followed by the development of B cell malignancies. The overexpression of miR155 in these transgenic mice closely resembles human lymphoproliferative diseases, making them valuable tools for exploring novel therapeutic strategies for B cell malignancies like acute lymphoblastic leukemia and high-grade lymphomas.
