mCD14是由含有CD14基因的单核细胞、 巨噬细胞,自行转录、翻译蛋白质多肽链,在 高尔基复合体 内糖化后,其 羧基端 再与PI结合,并由PI的 磷脂 部分与细胞膜连接 [4]。 IL-1β和 TNF -α能够调节CD14基因的表达,促进CD14 mRNA 的转录 [8];FMLP和 GM-CSF 可刺激 中性粒细胞,使其 细胞表面 的mCD14增多 [8]。 sCD14则是由 单核细胞 产生。 单核细胞产生sCD14的方式可能有两种:①由 内源性 酶促反应 (由 蛋白酶 或 磷脂酶 催化),使mCD14分解(脱去PI成 …
CD14 - Wikipedia
CD14 (cluster of differentiation 14) is a human protein made mostly by macrophages as part of the innate immune system. [5][6] It helps to detect bacteria in the body by binding lipopolysaccharide (LPS), a pathogen-associated molecular pattern (PAMP).
CD14—细菌脂多糖的膜受体 - 知乎 - 知乎专栏
CD14 (cluster of differentiation 14)原称MY23抗原,是一种表面抗原,属细胞表面糖蛋白家族成员之一。 CD14基因编码的蛋白,优先表达于单核/巨噬细胞。 CD14是革兰阴性菌内毒素脂多糖 LPS 和LPS结合蛋白 (LBP)复合物的高亲和力受体。 CD14识别并结合LPS,引起细胞酪氨酸磷酸化、核因子NF-κB转位、触发细胞因子释放和氧自由基产生,在机体免疫、防御系统引起的一系列反应中发挥重要作用。 1. CD14的发现. 1981年,Todd首次从人单核细胞表面发现了CD14。 1985 …

Role of CD14 in human disease - PMC - PubMed Central (PMC)
The cell surface antigen CD14 is primarily understood to act as a co-receptor for toll-like receptors (TLRs) to activate innate immunity responses to pathogens and tissue injury in macrophages and monocytes. However, roles for CD14 are increasingly being uncovered in disease responses in epithelial and endothelial cells.
CD14: Biology and role in the pathogenesis of disease
2019年8月1日 · Human monocyte differentiation antigen CD14 is a pattern recognition receptor (PRR) that enhances innate immune responses. CD14 was first identified as a marker of monocytes to signal intracellular responses upon bacterial encounters. Given the absence of an intracellular tail, CD14 was doubted to have the signaling capacities.

CD14的介绍:白细胞分化抗原与LPS受体的双重身份解析_生物器材网
2024年4月2日 · mCD14是一种分子量为5.3万~5.5万的糖蛋白,主要通过糖基磷脂酰肌醇(glycosylphosphatidylinositol,GPI)锚着在细胞膜上,少数mCD14也可通过跨膜肽与细胞膜结合,其附膜形式不影响其功能活性。 mCD14在细胞内合成后,先在高尔基复合体内糖化,其羧基端再与GPI结合,通过GPI的磷脂部分附着在细胞膜上。 sCD14存在于人和许多动物血清或血浆内,其蛋白质结构与mCD14 蛋白质结构相同,但不含GPI结构,故分子量较mCD14小,为4.8万 …
