炎症可能在某些恶性肿瘤的早期发生中起作用。白细胞介素(IL)-15,一种促炎细胞因子和生长因子,是淋巴细胞稳态所必需的。有趣的是,IL-15蛋白的表达受到多种转录后机制的严格控制。在这里,我们通过消除这些转录后检查点来改造转基因小鼠以过表达IL-15。IL-15转基因小鼠具有自然杀伤(NK)和CD 8 + T淋巴细胞的早期扩增。后来,这些小鼠发展为具有T-NK表型的致命淋巴细胞白血病。这些数据提供了新的证据,表明白血病,像某些其他癌症,可以作为慢性刺激的结果,由促炎细胞因子。
Inflammation likely has a role in the early genesis of certain malignancies. Interleukin (IL)-15, a proinflammatory cytokine and growth factor, is required for lymphocyte homeostasis. Intriguingly, the expression of IL-15 protein is tightly controlled by multiple posttranscriptional mechanisms. Here, we engineered a transgenic mouse to overexpress IL-15 by eliminating these posttranscriptional checkpoints. IL-15 transgenic mice have early expansions in natural killer (NK) and CD8+ T lymphocytes. Later, these mice develop fatal lymphocytic leukemia with a T-NK phenotype. These data provide novel evidence that leukemia, like certain other cancers, can arise as the result of chronic stimulation by a proinflammatory cytokine.
