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。
CD69、CD25、CD38、HLA-DR这四个细胞活化标记的意义和区别?
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 ...

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: from activation marker to metabolic gatekeeper - PubMed
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 …

Unraveling CD69 signaling pathways, ligands and laterally …
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 immunoregulatory molecule induced following activation
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.
