Natural killer (NK) cells are a discrete subset of lymphocytes of the innate immune response. They are rapid mediators of cytotoxicity against a variety of 'stressed cells' that include microbe-infected cells, transformed cells or cells in distress as a result of physical or chemical injuries. ...
Natural Killer Cells Natural killer (NK) cells, the first line of defense against viral infection, parasites, and tumor cells, are generally regarded as a key component of the innate immune system. They can promote inflammation by secreting tumor necrosis factor α (TNF-α) and IFNγ but also...
解析 自然杀伤细胞(natural killer cell): 即NK 细胞,又称大颗粒淋巴细胞,来源于骨髓,CD56和CD16是其具有鉴别意义的表面标志。NK 细胞表面没有抗原识别受体,可以直接或通过 ADCC 效应非特异性杀伤肿瘤细胞和病毒感染细胞。结果一 题目 自然杀伤细胞〔Natural killer cell,NK〕 答案 自然杀伤细胞〔natural killer ...
The article provides information on natural killer (NK) cells. A recent research has showed that NK cells may have more traits in common with cells of the adaptive immune system, including the concept of immunological memory. The latest discovery supported this notion indicating that NK cells ...

自然杀伤细胞,也称为NK 细胞或大颗粒淋巴细胞( LGL ),是一种对先天免疫系统至关重要的细胞毒性 淋巴细胞。它们属于快速扩增的已知先天淋巴细胞(ILC)家族,占人类所有循环淋巴细胞的 5-20%。 NK 细胞的作用类似于脊椎动物适应性免疫反应中的细胞毒性 T 细胞。NK 细胞基于来自几种激活和抑制受体的信号,对病毒感染细...
NK 细胞 通常,您的身体会对以前未知的威胁做出第一、立即的反应。 由于NK 细胞功能会随着年龄的增长而下降,我们应该考虑在冬季采取特殊措施来补充这一免疫的重要组成部分。功能。 ,与 现实世界对病毒感染和恶性肿瘤病例的影响都得到了证明。...
Natural killer (NK) cells are a discrete subset of lymphocytes characterized by a unique array of phenotypic markers (CD3/CD16+/CD56+). They are rapid mediators of cytotoxicity against infected or transformed cells and potent producers of lymphokines. Through these functions, they act as both eff...
自然杀伤细胞(natural killer cell,NK)是机体重要的免疫细胞,不仅与抗肿瘤、 抗病毒感染和免疫调节有关,而且在某些情况下参与超敏反应和自身免疫性疾病的发生,能够识别靶细胞、杀伤介质。 “癌症”这个词几乎让人闻声色变。数据显示,我国...
