CD4~+CD25~+调节性T细胞(Treg)在自身免疫疾病的研究中备受关注,作为肿瘤免疫的主要效应细胞,其对肿瘤的治疗及预后起着关键性的作用。卵巢癌作为女性生殖器常见的三大恶性肿瘤之一,由于其解剖位置的特殊性,早期不易发现,晚期病例也缺乏有效的治疗手段。因此,本文旨在通过对CD4~+CD25~+Treg的概述以及现有涉及CD4~+CD25~+Treg与卵 CD4 ~ + CD25 ~ + regulatory T cells (Treg) in the study of autoimmune diseases in the attention, as the main effector cells of tumor immunity, which plays a key role in the treatment of cancer and prognosis. As one of the three most common malignant tumors of female genitalia, ovarian cancer is not easy to be found early due to the particularity of its anatomic location. In the late stage, ovarian cancer also lacks effective treatment. Therefore, this article aims to summarize the CD4 ~ + CD25 ~ + Treg and the existing CD4 ~ + CD25 ~ + Tregs and eggs
