2023年5月24日 · cd69作为淋巴细胞活化最早表达的分子，也就是当免疫系统激活时，cd69成为最早的信号，调节t细胞、b细胞、自然杀伤细胞等多种免疫细胞的功能，因此，cd69被认为是一种多向性调控者，在免疫系统中发挥着重要的作用。

2021年4月7日 · 这些研究表明，cd69是t细胞活化后上调的 最早标志物之一，cd69表达的早期动力学和广泛分布使其成为在体外刺激试验中鉴定抗原反应性t细胞并有效纯化这些细胞的理想方法。但是，由于它会随细胞增殖而稀释，因此不能用于长期刺激试验。

2021年7月25日 · cd69是细胞表面糖蛋白，属于c型选择素受体家族，是t细胞活化后上调的最早标志物之一。它在静止的淋巴细胞中以非常低的基础水平表达，一旦被植物血凝素激活（通过tcr激活的促分裂原）激活，1-2h即可在t细胞表面发现cd69，且其表达会在3-12小时之间呈时间依赖 ...

cd69 和 cd25 会通过 tcr 信号转导出现上调，但有不同动力学特征，cd69 可在 tcr 连接后数小时内被检测到，而 cd25 则在之后增加。 由不良效应子功能界定的且在慢性感染和癌症期间出现的 T 细胞耗竭以 PD-1、TIM-3 和 LAG3 表达为特征；但这些分子还会在 T 细胞激活 ...

2023年5月24日 · cd69是淋巴细胞激活后最早表达的表面抗原，后来发现经诱导后它几乎可在所有的血细胞上表达。cd69可诱导表达在t细胞、b细胞、nk细胞、单核细胞、中性和嗜酸性粒细胞、胸腺细胞等。cd69这种仅在细胞活化后表达的特性，使其成为细胞活化的标记分子。

2024年12月24日 · CD69 (CD69 Molecule) is a Protein Coding gene. Diseases associated with CD69 include Coccidioidomycosis and Eosinophilic Pneumonia. Among its related pathways are Extrafollicular and follicular B cell activation by SARS-CoV-2 and Hematopoietic Stem Cells and Lineage-specific Markers.

CD69 is a membrane-bound, type II C-lectin receptor. It is a classical early marker of lymphocyte activation due to its rapid appearance on the surface of the plasma membrane after stimulation. CD69 is expressed by several subsets of tissue resident immune cells, including resident memory T …

CD69 is an early leukocyte activation marker involved in the regulation of the immune response. Initial in vitro studies evaluated its function using monoclonal antibodies until knock-out mice were developed. Subsequently, four ligands for CD69 have been identified, namely galectin-1, S100A8/S100A9 complex, myosin light chains 9 and 12, and ...

CD69 is an early leukocyte activation molecule expressed at sites of chronic inflammation. The precise role of CD69 in immunity has not been elucidated owing to the absence of a known ligand and adequate in vivo models to study its physiological function.
