摘要/Abstract

摘要：

胰腺导管腺癌（PDAC)是一种高度恶性的消化系统实体肿瘤，能影响机体免疫系统功能。PDAC病人外周循环和肿瘤微环境中的免疫细胞在分布、百分比、功能、活性等特征上均呈现出异常表现。T细胞是参与细胞免疫和发挥抗肿瘤效应的主要淋巴细胞，根据功能和分化抗原不同，可以分为CD4⁺、CD8⁺、CD4⁺ CD25⁺等亚群。PDAC病人循环免疫及肿瘤微环境中T细胞亚群水平的异常可能是促进肿瘤发生发展的重要因素。

关键词: 胰腺导管腺癌, 循环免疫, 肿瘤微环境, T细胞亚群

Abstract:

Pancreatic ductal adenocarcinoma (PDAC) is a highly malignant solid tumor of digestive system, which can affect the immune system. The abnormalities of distribution, percentage, function, and activity of immune cells in both peripheral circulation and tumor microenvironment (TME) are detected in patients with PDAC. T cells are the main lymphocytes that participate in cell-mediated immunity and exert anti-tumor effects. According to the function and the cluster of differentiation, T cells can be divided into different subsets, such as CD4⁺, CD8⁺, CD4⁺ CD25⁺, etc. The abnormalities of T cell subsets in the circulating immunity and TME of patients with PDAC may play an important role in cancer progress.

Key words: Pancreatic ductal adenocarcinoma (PDAC), Circulating immunity, Tumor microenvironment (TME), T cell subset
