Cancer Research | 三级淋巴结构中的细胞亚型做为癌症复发的预测标志物
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">越来越多的证据<span style="color: black;">显示</span>肿瘤浸润淋巴细胞的空间组织关系可能是肿瘤<span style="color: black;">发展</span>和治疗反应的<span style="color: black;">重点</span>决定<span style="color: black;">原因</span>。<span style="color: black;">因此呢</span>,绘制和分析精细的肿瘤免疫微环境结构可能为预测癌症预后<span style="color: black;">供给</span>新的见解。近期Cancer research杂志<span style="color: black;">发布</span>了一项探索性和前瞻性的临床<span style="color: black;">科研</span>,用来<span style="color: black;">评定</span>肿瘤微环境内的结构<span style="color: black;">是不是</span><span style="color: black;">能够</span>预测头颈鳞状细胞癌(HNSCC)的术后复发。该<span style="color: black;">科研</span><span style="color: black;">运用</span><strong style="color: blue;">PhenoCycler-Fusion(PCF)空间单细胞蛋白组</strong>(原CODEX)检测了<span style="color: black;">重点</span>的免疫亚群。空间<strong style="color: blue;">细胞邻域</strong>分析<span style="color: black;">发掘</span>了高频率的由<strong style="color: blue;">CD31highCD38high 浆细胞</strong><span style="color: black;">构成</span>的三级淋巴结构(TLS)与HNSCC术后复发率降低<span style="color: black;">明显</span><span style="color: black;">关联</span>。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">经过</span>PCF空间单细胞蛋白组技术对来自9个病人的组织全片进行了30个抗体的检测,这些抗体<span style="color: black;">能够</span>识别<span style="color: black;">重点</span>的淋巴细胞亚群、肿瘤细胞、血管和基质细胞。质控之后对79万多个单细胞进行了定义,总共注释了20种细胞亚型,说明了肿瘤微环境<span style="color: black;">繁杂</span>的细胞<span style="color: black;">构成</span>。</p>

<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">空间关系分析定义了11个<strong style="color: blue;">细胞邻域(cellular neighborhood, CN)</strong>。这些<strong style="color: blue;">CN</strong>由不同的细胞类型<span style="color: black;">构成</span>,反映了不同细胞类型间在空间上存在<span style="color: black;">繁杂</span>的互作关系。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><img src="//q1.itc.cn/images01/20240228/d41bd1cdce80467d8bceeea07564f5d6.png" style="width: 50%; margin-bottom: 20px;"></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">对<span style="color: black;">每一个</span><strong style="color: blue;">CN</strong>中细胞类型进行配对细胞-细胞互作分析(pairwise cell–cell contacts)<span style="color: black;">发掘</span>了有些<strong style="color: blue;">CN</strong>中同源性互作占主导,有些<strong style="color: blue;">CN</strong>中<span style="color: black;">重点</span>是异源性互<span style="color: black;">做为</span>主。异源性互作占比最多的是<strong style="color: blue;">TLS1</strong>、<strong style="color: blue;">TLS2</strong>和<strong style="color: blue;">hot tumor</strong> 这3个<strong style="color: blue;">CN</strong>。<strong style="color: blue;">例如浆细胞主导了TLS1<span style="color: black;">周边</span>的细胞相互<span style="color: black;">功效</span>。这些细胞与其他浆细胞相互<span style="color: black;">功效</span>,还与CD90+ MSC-like细胞、血管细胞以及CD4+和CD8+T细胞相互<span style="color: black;">功效</span>。对比之前的<span style="color: black;">科研</span>说明TLS1或许<span style="color: black;">相关</span>好的预后。而在TLS2中,M2型巨噬细胞主导了相互<span style="color: black;">功效</span>,这些巨噬细胞与Treg、PMN-MDSC、CD4+和CD8+ T细胞相互<span style="color: black;">功效</span>,暗示了TLS2中或许与<span style="color: black;">控制</span>抗肿瘤免疫<span style="color: black;">关联</span>。</strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;">在hot tumor中,大约三分之一的肿瘤细胞与淋巴细胞亚群接触,例如中性粒细胞、CD4+ 和CD8 +T细胞,还有M2巨噬细胞和PMN-MDSC。相比之下,在cold tumor中,大<span style="color: black;">都数</span>肿瘤细胞是同类型的互作。</strong></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><strong style="color: blue;">总之,这些CN对于肿瘤生长和免疫逃逸或有效抗肿瘤免疫的产生可能<span style="color: black;">拥有</span><span style="color: black;">要紧</span>的功能。</strong></p>
