Abstract

血管免疫母细胞性T细胞淋巴瘤(AITL)是较常见的外周T细胞淋巴瘤,不同患者临床过程、预后及对治疗的反应差异较大。AITL肿瘤微环境(TME)的细胞数量和成分可变,除肿瘤细胞外,还包括非肿瘤细胞和基质,如肿瘤浸润淋巴细胞(tumor infiltrating lymphocytes,TILs)、巨噬细胞、肥大细胞等,以及丰富的细胞因子成分,其中,TILs是TME的关键成员,可能对AITL的发生发展具有重要意义。本文将从AITL中TILs的主要构成与预后、不同TILs与治疗的关系及其研究方法等进行综述,总结AITL中TILs的特征并探讨其潜在的临床意义,以期寻找免疫治疗的新靶点,开辟AITL免疫药物治疗研发的新领域。.
