GUT:高脂饮食会影响精子的运动能力 

2020-08-11 MedSci原创 MedSci原创

在多数人印象中,高脂饮食会让人变胖,其实,除了致胖,还可能导致你患上不育哦!

        在多数人印象中,高脂饮食会让人变胖,其实,除了致胖,还可能导致你患上不育哦!不育是一种影响着全球大约10%-15%育龄夫妇的一种公共健康问题,对男性不育的评估和分类依赖于对其精液的分析,这其中包括三个参数,即精子的浓度、形态和运动性。越来越多的数据表明,生活方式或会通过改变机体的内分泌特征、精子发生和精子的功能来影响男性的生育力。有研究显示,肥胖的雄性小鼠容易生下不健康的后代,而最近一项研究证实高脂饮食是通过影响肠道菌群进而影响精子的发生和运动能力的。

        研究人员做了一项试验,将高脂饮食(HFD)的肠道微生物移植到正常饮食(ND)的小鼠中,发现小鼠的精子发生和精子活力显着降低,而用ND喂养的小鼠进行的类似移植却未能起到这样明显的改善作用。对微生物群的分析显示,拟杆菌属和普雷沃氏菌属大量增加,这两者都可能导致了HFD-FMT小鼠的代谢性内毒素血症。有趣的是,来自临床受试者的肠道微生物显示,拟杆菌属和拟杆菌属的丰富度与精子运动之间呈负相关,血液内毒素与拟杆菌属之间呈正相关。用HFD微生物移植还导致T细胞和巨噬细胞的肠道浸润以及附睾中促炎性细胞因子的显着增加,这表明附睾炎症很可能导致了精子活力的损害。RNA测序显示,HFD-FMT小鼠中参与配子减数分裂和睾丸线粒体功能的那些基因的表达显着降低。

        最后研究者说道。高脂饮食(HFD)引起的微生物群失调与精子发生缺陷之间的密切联系,内毒素升高,睾丸基因表达失调和局部附睾炎症是潜在的原因。

Blood:高脂饮食以血栓调节蛋白依赖性方式延迟血浆纤溶酶的产生

中心点:一项新的实验显示,高脂肪饮食小鼠血浆纤溶酶的生成延迟。蛋白质组学和功能分析表明,是凝血调节蛋白和TAFI依赖性机制导致纤溶酶生成延迟。摘要:肥胖是一种常见的血栓形成前危险因素,其特征是纤维蛋白形成增强和纤维蛋白溶解抑制。纤维蛋白不仅可促进血栓形成,还可驱动肥胖病理生理,但是由于缺乏必要的分析工具,肥胖导致纤溶的机制仍不明确。采用纤溶酶特异性荧光基质,研究人员开发了一种血浆纤溶酶生成 (PG

PNAS:一胖毁三代?高脂饮食引起的肥胖会跨代传递,并且这还不是全部……

最近发表于《美国国家科学院院刊》上的一项研究显示,母亲营养过剩,会将肥胖和代谢障碍传给直系后代,甚至会传到第三代。苏黎世大学的Gitalee Sarker博士与其同事给母鼠喂食高脂饮食诱导肥胖后,发现母鼠所生的儿子们会通过精子中的一类RNA分子继续影响第三代,不仅跨代传递肥胖,还让第三代出现了容易“沉溺于享乐”的行为,比如对酒精、药物等成瘾物质更敏感。

高脂饮食不仅导致肥胖,还会导致抑郁

近日,来自格拉斯哥大学和格莱斯顿研究所的研究人员发现了导致肥胖的高脂饮食与抑郁发生的联系,他们采用脂质组学和转录组学的方法,发现下丘脑中膳食脂肪酸可干扰cAMP/PKA信号通路,进而导致抑郁的发生。

Mol Psychaitr:颠覆认知!妊娠期间母亲高脂饮食可以预防后代阿尔茨海默症

高脂肪饮食可能会带来健康风险,但对准妈妈们来说,当涉及到为孩子预防阿尔茨海默症时,高脂肪饮食可能会带来很大的不同。
