JCLA:通过对健康人群中干扰素-γ水平的测量,揭示了中性粒细胞-淋巴细胞比和自然杀伤细胞活性之间的关系

2019-06-01 不详 网络

虽然目前已经有通过测量NK细胞释放的大量的γ干扰素(IFN)方法来分析自然杀伤(NK)细胞活性,但是目前仍没有数据可用于分析影响干扰素γ水平与NK细胞活性的因素。最近报道表明NLR可作为几种疾病的预测因子。在目前的研究中,我们通过测量干扰素γ和NLR和NK细胞活性之间的关系分析了NK细胞活性分析前变量。

虽然目前已经有通过测量NK细胞释放的大量的γ干扰素(IFN)方法来分析自然杀伤(NK)细胞活性,但是目前仍没有数据可用于分析影响干扰素γ水平与NK细胞活性的因素。最近报道表明NLR可作为几种疾病的预测因子。在目前的研究中,我们通过测量干扰素γ和NLRNK细胞活性之间的关系分析了NK细胞活性分析前变量。

研究人员通过NK细胞兴奋剂(NK Vue, ATgen) 刺激细胞评估NK细胞活性。本研究招募106名成年志愿者,并对他们的全血细胞计数数据和血清C‐反应蛋白进行了分析。其中,59名参与者的血液样本也被用来分析淋巴细胞亚群。

研究表明,自然杀伤细胞活性差异很大(范围为44.21775.6 pg/mL)。女性NK细胞活性高于男性(P = 0.014)NK细胞活性随NLR的增加而降低(P = 0.004, r = - 0.32),但NK细胞活性与NK细胞计数或其他淋巴细胞亚群无显著相关性。CRP四分位数与NK细胞活性水平有显著性差异(P = 0.025)

评估时我们发现NK细胞活性,干扰素γ标高测量与NLR负相关。这一结果对于解释或预测NK细胞在临床环境中的活性有一定的帮助。
