概括

增加的总巨细胞和M2巨细胞与声音刺细胞瘤的更好的结果相关. 与瘤相关的巨细胞 (TAMs),特别是M2类型,可能代表这种脑瘤的治疗标.

科学领域:

神经瘤学神经瘤学
免疫学免疫学免疫学
病理学病理学病理学

背景情况:

瘤相关巨细胞 (TAMs) 是脑瘤瘤微环境 (TME) 的关键组成部分.
巨细胞两极分化显著影响TME,但它们在声波刺 (SHH) 脑膜细胞瘤中的特定作用尚不清楚.

研究的目的:

调查TAMs在SHH髓母细胞瘤中的极化特征和影响.
分析TAM透和SHH髓母细胞瘤患者的临床结果之间的相关性.

主要方法:

使用多重免疫光染色对42个SHH髓母细胞瘤患者样本的分析.
检测M1和M2巨细胞表型 (CD68,HLA-DR,CD163) 和与临床特征和预后因素的相关性.

主要成果:

在年轻患者 (<5岁) 中观察到更高的M_total (总巨细胞) 和M_mix (CD68+HLA-DR+CD163+).
在非转移性病例中,M_total较高. 在经典脑膜母细胞瘤 (CMB) 中,M2巨细胞的发病率更高,相比之下,在脱质/结节性脑膜母细胞瘤 (DNMB) /具有广泛结节性脑膜母细胞瘤 (MBEN) 中,M2巨细胞的发病率更高.
高M_总和M2巨细胞水平与更好的5年无进展生存率 (PFS) 和整体生存率 (OS) 相相关,M2巨细胞是独立的预后因素.

结论:

增加的总和M2巨细胞水平预测了SHH髓母细胞瘤的改善结果.
TAMs,特别是M2巨细胞,代表了SHH髓母细胞瘤的潜在治疗标.

The Tumor Microenvironment

The Tumor Microenvironment

Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...
