中文摘要
本研究描述了一套高效的工作流程,可从人外周血单核细胞生成功能性树突状细胞(DC),并将其应用于抗原特异性T细胞激活实验。单核细胞被分化为高表达共刺激分子和MHC分子的成熟DC。当用特定抗原致敏并与自体T细胞共培养时,这些DC能有效激活CD4+、CD8+和调节性T细胞群体,这一点通过增殖实验和细胞因子谱分析得到证实。不同T细胞亚群之间的差异化激活动力学为抗原特异性免疫应答的时相动态提供了见解。我们的工作流程展示了一种标准化方法,为研究DC-T细胞相互作用、评估候选疫苗以及评估抗原特异性T细胞应答提供了可靠的研究平台。此外,我们可重复的工作流程可作为免疫学研究应用中的宝贵工具,包括疫苗开发、肿瘤免疫治疗和自身免疫性疾病研究。

This study describes an efficient workflow to generate functional dendritic cells (DCs) from human peripheral blood monocytes and their application in antigen-specific T cell activation assays. Monocytes were differentiated into mature DCs expressing high levels of co-stimulatory molecules and MHC molecules. When pulsed with specific antigens and co-cultured with autologous T cells, these DCs effectively activated CD4+, CD8+, and regulatory T cell populations, as demonstrated by proliferation assays and cytokine profiling. The differential activation kinetics between T cell subsets provided insights into the temporal dynamics of antigen-specific immune responses. Our workflow demonstrates a standardized approach that offers a reliable research platform to investigate DC-T cell interactions, evaluate vaccine candidates, and assess antigen-specific T cell responses. Furthermore, our reproducible workflow may serve as a valuable tool for applications in immunology research, including vaccine development, cancer immunotherapy, and autoimmune condition studies.
