Description :CD223, also known as LAG-3, is a 70 kD type I transmembrane glycoprotein that is involved inT-cell signaling. Similar to CD4, CD223 binds MHC class II, but with a higher affinity. CD223negatively regulates T-cell activation. It is expressed by activated T-cells and natural killer cells(NKs), as well as regulatory T-cells. It is transiently expressed on the surface of activated Tcells in acute conditions but high expression is maintained under tolerizing conditions. CD223deficiency results in reduced tumor growth. CD223 and PD-1 can act in synergy and reverseexhausted phenotypes, improve tumor rejection, and control viral load.

流式课堂 | 易被忽略的 CD4、CD8 共表达细胞——胸腺淋巴细胞
做过流式实验的同学,对 CD4、CD8 这两个指标都不会陌生。检测 CD4+ T 细胞和 CD8+ T 细胞分型,是流式中最常见的实验之一。 通常,我们会先检测 CD3,来圈总T淋巴细胞,再分别用 CD4 抗体和 CD8 抗体,来区分 CD4+ T 淋巴细胞(辅助或调节性T细胞)和 CD8+ T 淋巴细胞(细胞毒性 T 细胞)。 新生小鼠脾脏细胞 上图为新生小鼠脾脏细胞进行的 CD3-PE、CD4-FITC、CD8-APC 三色流式实验结果。从图中可以看出,在新生小鼠脾脏中,绝大
69、CD38 等活化指标,及 IFN-γ、IL-4、IL17A 等细胞因子,则需要设置同型对照,实现阴阳性细胞群的良好区分。 CD4 CD25 (2)在某些特殊情况下,如单核细胞被 PE/Cyanine 7、APC/Cyanine 7 等串联染料标记的抗体染色时,使用同型对照抗体是十分有必要的。单核细胞一般倾向于与 Cyanine7 等染料非特异性结合,使用同型对照抗体有助于获得理想结果。 (3)不清楚抗原表达情况的时候,一定要使用同型对照来界定阴性细胞群。 (4)胞内染色时
