摘要: 黑色素瘤缺乏因子(Absent in melanoma 2,AIM2),作为一种细胞内DNA感受器,能够感受到DNA病毒或细菌感染时释放到细胞浆的dsDNA,经ASC产生炎症复合体,进而活化Caspase-1,引起炎症因子IL-1β和IL-18的成熟和分泌,或引起Pyroptosis样细胞死亡,因此AIM2在固有免疫应答中发挥重要作用。近年的研究显示,AIM2能影响肿瘤的发生与发展,在肝癌、乳腺癌中表现为抑癌因子,抑制肿瘤的进展;在宫颈癌、口腔鳞状细胞癌中却表现出致癌效应,促进肿瘤的发展。这些研究结果对恶性肿瘤的诊断及预后起到帮助作用。

Abstract: Absent in melanoma 2(AIM2),as a cytoplasmic DNA sensor,can perceive the cytoplasmic dsDNA which released by the cells infected with DNA virus or bacteria.AIM2 will be raised by Apoptosis-associated speck-like protein containing a CARD to produce inflammation complex,activate of Caspase-1,promote the maturation,and secretion of IL-1β and IL-18,or lead to pyroptosis.AIM2 plays an importation role in initiating immunity.Recent research shows that AIM2 has an influence on the occurrence and progress in tumor,it acts as a tumor suppressor and inhibits tumor progression in liver and breast carcinoma;However,AIM2 shows the carcinogenic effect of promoting tumor development on cervical carcinoma and oral squamous cell carcinoma.These results contribute to the diagnosis and prognosis of malignant tumor.

Key words: AIM2, Malignant tumor, Inflammasome
