[Research Progress in Transgenic Animal Models of Chronic Lymphocytic Leukemia -Review].

Transgenic mouse models of chronic lymphocytic leukemia (CLL) are crucially required for the elucidation of the underlying pathogenic mechanisms and for finding new therapies. So far, several mouse models have been established, mimicking either genetic aberrations or dysregulated gene expression in CLL. Among all the models, TCL1 transgenic model is the most commonly used one. Additionally, there are also other models, such as 13q14-deletion model. In this review, the major genetically engineered mouse models of CLL in current use are summarized, the main problems include TCL-1 transgenic mice, miR15a/16-1 gene knockdown mice and miR29 transgeneic mice, BAFF and APRIL transgeneic mice, BCL-2:Traf2DN double transgeneic mice, IRF4-/-Vh11 transgeneic mice and so on.
