| Function | Integral membrane glycoprotein that plays an essential role in the immune response and serves multiple functions in responses against both external and internal offenses. In T-cells, functions primarily as a coreceptor for MHC class I molecule:peptide complex. The antigens presented by class I peptides are derived from cytosolic proteins while class II derived from extracellular proteins. Interacts simultaneously with the T-cell receptor (TCR) and the MHC class I proteins presented by antigen presenting cells (APCs). In turn, recruits the Src kinase LCK to the vicinity of the TCR-CD3 complex. LCK then initiates different intracellular signaling pathways by phosphorylating various substrates ultimately leading to lymphokine production, motility, adhesion and activation of cytotoxic T-lymphocytes (CTLs). This mechanism enables CTLs to recognize and eliminate infected cells and tumor cells. In NK- cells, the presence of CD8A homodimers at the cell surface provides a survival mechanism allowing conjugation and lysis of multiple target cells. CD8A homodimer molecules also promote the survival and differentiation of activated lymphocytes into memory CD8 T-cells. |
| Cellular Location | Isoform 1: Cell membrane; Single-pass type I membrane protein Note=CD8A localizes to lipid rafts only when associated with its partner CD8B. |
| Tissue Location | CD8 on thymus-derived T-cells usually consists of a disulfide-linked alpha/CD8A and a beta/CD8B chain. Less frequently, CD8 can be expressed as a CD8A homodimer. A subset of natural killer cells, memory T-cells, intraepithelial lymphocytes, monocytes and dendritic cells expresses CD8A homo-dimers Expressed at the cell surface of plasmacytoid dendritic cells upon herpes simplex virus-1 stimulation. |

文献和实验。我们在这里介绍收集到的一些经验和最佳实践，建立可重复的工作流程的四个关键步骤，包括抗体组合开发、染色、图像采集和分析，可节省研究人员的时间，并最终提高药物发现和开发的效率。 1. 建立最佳抗体组合 使用 Opal 多重荧光免疫组化工作流程准确、可重复地鉴定组织中的不同细胞群及其关系，需要仔细设计、开发和优化用于多重生物标志物定量的抗体组合[1]。 a 从预先设计的抗体组合开始 要选择在多重荧光免疫组化中具有高灵敏度、特异性、再现性和优异性能的可识别所需靶标的抗体似乎并不那么容易
Nature Cancer I 生物标志物多参数评估mTLS预测实体瘤免疫治疗效果
TLS 成熟度，需要对 CD8、CD4、CD20、CD21 和 CD23 进行多参数分析。 阻断 PD-1 受体与其主要配体 PD-L1 之间的相互作用具有显著抗癌作用，已有多种抗 PD-1 或抗 PD-L1 药物被批准用于多种实体瘤治疗。然而，大多数接受抗 PD-1 或抗 PD-L1 单克隆抗体的患者并没有从中获益。 免疫组织化学、肿瘤突变负荷 (TMB) 和微卫星不稳定性状态评估的 PD-L1 表达状态是迄今为止唯一被批准用于指导抗 PD-1 治疗的伴随诊断标志物。这些方法并不能有效区分出可能
