IL-7在人类健康和疾病中起着许多重要作用。IL-7信号传导的先天性缺陷导致严重的免疫缺陷,IL 7 R α的多态性调节对自身免疫性疾病的易感性,IL 7 R α的获得性体细胞激活突变有助于B细胞和T细胞白血病的肿瘤转化。响应于淋巴细胞减少症,IL-7积累至超正常水平,这通过增强T细胞对自身和同源抗原的反应性来改变T细胞稳态。这种生理反应现在被常规地用于提高癌症过继细胞疗法的功效。重组IL-7的临床试验已经证明了安全性和有效的免疫恢复作用,目前的研究正在调查rhIL-7治疗是否可以改善慢性病毒感染和癌症免疫治疗的结果。基于大量的关于IL-7的基础生物学的知识,本文将讨论IL-7在人类健康和疾病中的许多不同的作用。
IL-7 plays many essential roles in human health and disease. Congenital deficiencies in IL-7 signaling result in profound immunodeficiency, polymorphisms in IL7Rα modulate susceptibility to autoimmune disease, and acquired somatic activating mutations in IL7Rα contribute to neoplastic transformation in B cell and T cell leukemia. In response to lymphopenia, IL-7 accumulates to supranormal levels, which alters T cell homeostasis by augmenting T cell reactivity toward self and cognate antigens. This physiologic response is now routinely exploited to improve the efficacy of adoptive cell therapies for cancer. Clinical trials of recombinant IL-7 have demonstrated safety and potent immunorestorative effects, and current studies are investigating whether rhIL-7 therapy can improve outcomes in chronic viral infection and in the context of cancer immunotherapies. Building upon the large fund of knowledge regarding the basic biology of IL-7, this review will discuss the many and varied roles of IL-7 in human health and disease.
