Murine models of disease are vital to the understanding of pathogenesis and the development of novel therapeutics. We have previously established interleukin (IL)-15 transgenic (tg) mice that demonstrate rapid proliferation of natural killer (NK) and T cells, followed by spontaneous transformation to lethal leukemia. Herein, we have characterized this model, which has many features in common with the aggressive variants of NK and T large granular lymphocyte leukemia (LGLL) in humans. The LGLL blasts are cytolytic and produce IFN-gammaex vivo. Cytogenetic analysis revealed trisomy of chromosome 17 and/or 15. This model should provide opportunities to develop effective standard therapies for this fatal disease.
疾病的小鼠模型对于理解发病机制和开发新型治疗方法至关重要。我们之前建立了白细胞介素(IL)-15转基因(tg)小鼠,这些小鼠表现出自然杀伤(NK)细胞和T细胞的快速增殖,随后自发转化为致死性白血病。在此,我们对该模型进行了表征,它具有许多与人类NK和T大颗粒淋巴细胞白血病(LGLL)侵袭性变体相同的特征。LGLL母细胞具有细胞溶解性,并且在体外产生γ干扰素。细胞遗传学分析显示17号和/或15号染色体三体性。该模型应为开发针对这种致命疾病的有效标准疗法提供机会。
