轮班工作会损害免疫细胞的反应,导致炎症减弱和感染风险增加. 这项研究揭示了轮班工人炎症信号之间的干扰联系,突出了潜在的健康风险.
科学领域:
- 免疫学 免疫学 免疫学
- 职业健康 职业健康 职业健康
- 睡眠医学 睡眠医学
背景情况:
- 轮班工作影响了近30%的美国劳动力.
- 长期轮班工作与慢性全身炎症和增加感染易感性有关.
- 轮班工人的细胞介导免疫反应尽管存在慢性免疫激活,但仍然不太了解.
研究的目的:
- 研究轮班工作对细胞介导炎症反应的影响.
- 为了比较轮班工人和健康的日班工人之间的免疫细胞反应能力.
主要方法:
- 从轮班和日班工人中分离了周围血液单核细胞 (PBMC).
- 用脂聚糖 (LPS) 刺激PBMC,以评估炎症和抗炎症反应.
- 血脂多糖结合蛋白 (LBP) 水平被测量为全身炎症的标志物.
主要成果:
- 轮班工人的PBMC表现出对LPS的抑制炎症反应,TNF-α分泌量显著降低.
- 抗炎性IL-10分泌在两组中都是相似的.
- 血LBP和LPS诱导反应之间的相关性在轮班工人中被破坏.
结论:
- 轮班工作破坏细胞介导免疫力,以低反应性PBMCs为特征.
- 削弱亲和抗炎信号的受损机制可能是这种低反应的基础.
- 这些免疫干扰增加了轮班工人感染和炎症相关病理的风险.

Carbohydrate Metabolism
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in the...
