概括
在皮肤T细胞淋巴瘤 (CTCL) 中,CD5的表达有所不同. 恶性T细胞在早期显示CD5的增加,但晚期瘤通常会失去CD5,影响向治疗的有效性.
科学领域:
- 免疫学 免疫学 免疫学
- 皮肤病学 皮肤病学
- 在瘤学瘤学.
背景情况:
- 皮肤T细胞淋巴瘤 (CTCL) 是一种皮肤恶性瘤,在晚期有不良结果.
- CD5是系统性淋巴瘤中CAR T细胞治疗的潜在标,但其在CTCL中的作用尚不清楚.
- 在CTCL中的恶性T细胞中,CD7和CD26的表达往往会丢失.
研究的目的:
- 分析最常见的CTCL亚型菌菌病 (MF) 中的CD5基因表达.
- 评估CD5表达与MF临床表现相关的CD5表达 (贴片/斑块与瘤阶段).
- 评估CD5在不同MF阶段作为治疗点的潜力.
主要方法:
- 单细胞RNA测序 (scRNA-seq) 来自5个贴片/斑块MF活检,8个瘤MF活检和8个健康对照活检.
- 在CD4 T细胞上分析病变特异性CD5基因表达.
- 亚组分析比较CD5表达在贴片/斑块和瘤阶段MF之间的CD5.
主要成果:
- 恶性MF CD4 T细胞 (21.1%) 的CD5表达明显高于健康对照组 (5.2%).
- 补丁/斑块MF活检显示CD4 T细胞中的CD5表达高于瘤阶段MF活检.
- 与补丁/斑块MF (76.6%的损失) 相比,晚期瘤阶段MF表现出显著的CD5损失 (94.3%的损失).
结论:
- 在MF中CD5表达是动态的,并且取决于临床病变类型.
- CD5可能是早期MF (贴片/斑块) 的可行的治疗标.
- 由于抗原逃逸,CD5向可能在晚期MF中较不有效,瘤呈现.

Tumor Immunotherapy
1.7K
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

T Cell Activation and Clonal Selection
14.6K
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.
