概括

口腔状细胞癌 (OSCC) 显示了免疫调节分子的改变表达,如细胞毒性T-淋巴细胞相关蛋白4 (CTLA-4) 和其连接体,这表明免疫检查点抑制剂 (ICI) 的新诊断和治疗标.

科学领域:

免疫学免疫学免疫学
在瘤学瘤学.
分子生物学分子生物学

背景情况:

口腔状细胞癌 (OSCC) 的生存率很低,特别是在晚期.
免疫检查点抑制剂 (ICI) 在OSCC治疗中表现有前途.
了解OSCC中的免疫抑制对于开发新疗法至关重要.

研究的目的:

在OSCC中研究细胞毒性T淋巴细胞相关蛋白4 (CTLA-4),CD28及其配体CD80和CD86的差异表达.
评估这些分子在OSCC中的诊断和治疗意义.

主要方法:

分析mRNA表达的横截面研究.
用于分析的反转录-聚合酶连锁反应 (RT-PCR).
在104个OSCC样本中的表达水平与65个健康的口腔粘膜 (NOM) 样本之间的比较.

主要成果:

在OSCC中增加CTLA-4 (可溶性和膜结合) 的表达.
在OSCC中显著增加CD80和膜结合的CD86的表达.
没有观察到CD28或可溶性CD86表达的显著差异.

结论:

CTLA-4,CD80和膜结合的CD86表达与OSCC诊断有显著的相关性.
这些分子可能会改善OSCC的多标志物诊断方法.
在OSCC中,CD80似乎比CD86具有更强的免疫抑制作用,支持抗CTLA-4和抗CD80组合疗法.

T Cell Activation and Clonal Selection

T Cell Activation and Clonal Selection

T cells are integral to our adaptive immune system, recognizing and effectively responding to foreign antigens. T cell activation and clonal selection are pivotal in orchestrating this immune response. This article elucidates these mechanisms, detailing the roles of cluster of differentiation (CD) markers, major histocompatibility complex (MHC) molecules, costimulatory signals, and the process of clonal selection.
Naive T cells that have not yet encountered an antigen express two primary CD...
