摘要
T淋巴细胞是具有特异性免疫功能的一种白细胞，它接受抗原刺激变成致敏细胞后乃分化繁殖成具有免疫活性的细胞，其免疫作用包括排斥移植来的异体组织、破坏肿瘤细胞、抑制病毒与细胞繁殖等。炎症性肠病（IBD）是一种病因尚不十分清楚的慢性非特异性肠道炎症性疾病，包括溃疡性结肠炎（UC）和克罗思病（CD）。炎症性肠病与自身免疫密切相关，T淋巴细胞在其发生发展中发挥重要的作用。
T lymphocytes, as one kind of white blood cells with specific immune function, develop into sensitized cells under antigenic stimulation, and differentiate into immunological competent cells. The allergized T lymphocytes are mainly involved in graft rejection, killing tumor cells, and inhibition of virus and bacteria replication, etc. The inflammatory bowel diseases, as one kind of cause-undetermined, chronic, and non-specific intestinal tract inflammatory diseases, include ulcerative colitis （UC） and Crohn＇s disease （CD）. Inflammatory bowel diseases were closely related to autoimmunity and T lymphocytes play significant roles in their development.
