概括
阿波蛋白E4 (ApoE4) 基因存在没有影响类似流感的疾病或COVID-19的严重程度或持续时间. 年龄较大,男性性别,BMI较高和并发症增加了严重的COVID-19风险.
科学领域:
- 遗传学和传染病的研究
- 分子生物学和病毒学.
背景情况:
- 假设阿波利波蛋白E (ApoE) 基因型,特别是ApoE4异型,会影响呼吸道病毒感染的严重程度,但证据仍然不确定.
- ApoE4等位基因对类似流感综合征和COVID-19的特定影响需要进一步调查.
研究的目的:
- 调查Apolipoprotein E4 (ApoE4) 异型与流感状综合征的严重程度和持续时间之间的关联,包括2019年新冠肺炎疾病 (COVID-19).
主要方法:
- 在280个患有类似流感症状的人群中,Apolipoprotein E (ApoE) 异型的基因定型.
- 收集临床数据,并发症,营养状况,生化和炎症标志物以及SARS-CoV-2 PCR结果.
- 根据世卫组织的标准,分析疾病严重程度 (轻度,中度,严重),在COVID-19和非COVID-19类似流感综合征组中比较ApoE4携带者和非携带者.
主要成果:
- 在总人口,COVID-19和类似流感综合征群体 (17-18%) 中,ApoE4等位基因的频率相似.
- 在临床参数,并发症或炎症标志物中,在类似流感综合征组中,在ApoE4携带者和非携带者之间没有发现显著差异.
- 在COVID-19组中,ApoE4等位基因与疾病严重程度,持续时间,并发症或炎症生物标志物无关. 与中度至重度COVID-19增加相关的因素包括年龄较大,男性性别,BMI较高和并发症. 介素-4 (IL-4) 与严重疾病风险降低有关.
结论:
- ApoE4等位基因的存在似乎不会影响流感状综合征的持续时间或严重程度,包括COVID-19.
- 人口统计和临床因素,如年龄较大,男性性别,BMI升高和并发症是严重COVID-19的重要预测因素.
- 这个队列中的SARS-CoV-2-阳性个体的特点是年龄较大,男性性别,BMI较高,经常超重或肥胖.

During most eukaryotic translation processes, the small 40S ribosome subunit scans an mRNA from its 5' end until it encounters the first start AUG codon. The large 60S ribosomal subunit then joins the smaller one to initiate protein synthesis. The location of the translation initiation is largely determined by the nucleotides near the start codon as there may be multiple translation initiation sites present on the mRNA. Marilyn Kozak discovered that the sequence RCCAUGG (where R...

Simple proteins and protein complexes contain only amino acids. In contrast, many other proteins, called conjugated proteins, covalently bond with non-protein moieties.
Nucleoproteins are protein complexes that contain nucleic acids, categorized as deoxyribonucleoproteins (DNPs) or ribonucleoproteins (RNPs) respectively. The nucleosome is a typical example of a DNP where nuclear DNA is associated with histone proteins. The major antigen for the Covid-19 virus SARS-CoV is an RNP that is critical...
