概括
新的研究确定了特定的免疫细胞,如细胞皮肤居民巨细胞和树突细胞-T细胞群,可以预测皮肤状细胞癌 (cSCC) 在治疗后是否会复发.
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:
- 目前皮肤状细胞癌 (cSCC) 的基因病学分类在预测患者复发方面缺乏可靠性.
- 在初级瘤切除过程中,急需分子签名来分层cSCC患者.
研究的目的:
- 确定原发性cSCC的免疫格局,并确定分辨复发性和非复发性瘤的分子特征.
- 基于免疫细胞透和空间相互作用,发现cSCC的预后生物标志物.
主要方法:
- 使用高维成像质量细胞计与39个抗体面板的初级cSCC和周围皮肤样本.
- 采用空间解析的单细胞数据的计算分析来识别不同的免疫细胞子集.
- 在新鲜瘤活检上进行光谱流细胞计,以评估巨细胞的细胞性质.
主要成果:
- 确定了12个免疫细胞子集,使初级cSCC与周围皮肤区分开来,包括调节性T细胞,CD8+T淋巴细胞和瘤中的瘤相关巨细胞.
- 在皮肤中存在的巨细胞 (CD206+,CD11c+,HLA-DR+,CD14-) 更有效地透到非复发性瘤中,并显示出更高的增殖和细胞毒性.
- 在非复发性cSCC中观察到树突细胞 (DC-LAMP+) 和T淋巴细胞之间的近距离,表明活性适应性免疫.
结论:
- 细胞皮肤寄存巨细胞和树突细胞-T细胞群是区分非复发性cSCC和复发风险的关键特征.
- 这些发现为cSCC提供了潜在的预后生物标志物,有助于患者分层和治疗决策.

T Cell Activation and Clonal Selection
14.8K
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.

Skin Cancer
5.7K
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.
