项目摘要

COVID-19 continues to be a global catastrophe despite development of anti-SARS-CoV-2 vaccines. This is due to the worldwide limited vaccine availability, vaccination hesitancy, and the emergence of new variants of SARS- CoV-2. Moreover, there is a lack of complete knowledge about SARS-CoV-2 biology, including potential transmission routes and variable pathogenesis, especially in ethnic groups, such as African American (AA) and Hispanic/Latino that were disproportionally affected by COVID-19 compared to White Non-Hispanic (WNH) population. The role of biological factors contributing to high infection, hospitalization, and death rates in these groups remains to be investigated. Cell entry of SARS-CoV-2 depends on binding of the viral spike (S) protein to the host cell receptor ACE2 and its priming/cleavage by host protease TMPRSS2. It is well accepted that the main route of the SARS CoV-2 entry into the body is via respiratory epithelial cells. However, cells in other tissues/organs including the heart, kidney, pancreas, eye and skin (mostly epidermis) also express ACE2 and TMPRSS2. Some recent studies indicate that skin could be directly targeted by SARS-CoV-2. Indeed, viral RNA and capsid proteins were detectable in skin biopsies. Importantly, some inflammatory skin diseases, such as psoriasis and atopic dermatitis, significantly increased the risk of COVID-19. This correlates with the findings that ACE2 and TMPRSS2 expression was increased in lesional skin of psoriasis patients as well as in wounded skin. In addition, COVID-19 is associated with dermatological immediate or sometimes persistent manifestations which could occur because of direct (topical) or systemic (via circulating virus) infection by SARS-CoV-2. Nevertheless, the potential role of human healthy or inflamed skin in SARS-CoV-2 entry and COVID-19 pathogenesis has not been addressed. It is known that TNF-α, IL-6, IL-1β, and IFN-γ cytokines are involved in the development of different inflammatory skin diseases and their level is increased during cytokine storm frequently associated with viremia, multi-organ failure, and development of severe deadly COVID-19 . In our pilot experiments, we showed that combination of TNF-α + IL-6 + IL-1β + INF-γ strongly induced expression of ACE2 and TMPRSS2 in 3D human skin equivalents (3D-HSE) made from primary human epidermal keratinocytes (NHEK). Based on these novel findings, we hypothesize that inflamed skin could be infected by wild type SARS- CoV-2 virus and its emerging mutated variants, and that higher infection rates reported for specific ethnic populations may depend on higher expression levels of proteins involved in SARS-CoV-2 cell entry. To test these hypotheses, we will use pseudotyped Spike (S) protein-containing reporter lentiviruses, 2D- and 3D-HSE cultures made from AA, Hispanic and WNH keratinocytes pretreated with cytokine cocktails related to COVID- 19 cytokine storm (TNF-α+IL-6+IL-1b+INF-γ) or cytokines proven to induce pro-psoriasis (IL17+IL22+TNFa) or pro-atopic dermatitis (IL4+IL13) molecular and morphological changes in in vitro skin models.
尽管抗SARS-CoV-2疫苗已开发出来,COVID-19仍是全球性灾难。这是由于 由于全球疫苗供应有限,疫苗接种犹豫不决,以及SARS新变种的出现, 二型冠状病毒此外,缺乏关于SARS-CoV-2生物学的完整知识,包括潜在的 传播途径和可变的发病机制,特别是在种族群体中,如非洲裔美国人(AA)和 与白色非西班牙裔(WNH)相比,受COVID-19影响较大的西班牙裔/拉丁裔 人口生物学因素在这些疾病中的作用是导致高感染率、住院率和死亡率。 团体仍有待调查。SARS-CoV-2进入细胞依赖于病毒S蛋白的结合 与宿主细胞受体ACE 2的结合及其被宿主蛋白酶TMPRSS 2引发/切割。人们普遍认为, SARS CoV-2进入人体的主要途径是通过呼吸道上皮细胞。然而,其他细胞 包括心脏、肾脏、胰腺、眼睛和皮肤(主要是表皮)在内的组织/器官也表达ACE 2, TMPRSS 2.最近的一些研究表明,皮肤可能是SARS-CoV-2的直接靶点。事实上,病毒RNA 在皮肤活检中可检测到衣壳蛋白。重要的是,一些炎症性皮肤病,如 银屑病和特应性皮炎,显著增加了COVID-19的风险。这与研究结果相关, ACE 2和TMPRSS 2在银屑病患者皮损中的表达增加, 皮肤此外,COVID-19与皮肤病的即时或有时持续的表现有关 这可能是由于SARS-CoV-2的直接(局部)或全身(通过循环病毒)感染而发生的。 然而,人类健康或发炎皮肤在SARS-CoV-2进入和COVID-19中的潜在作用 发病机制尚未解决。已知TNF-α、IL-6、IL-1β和IFN-γ细胞因子参与了 在细胞因子风暴期间,不同炎症性皮肤病的发展及其水平增加 经常与病毒血症、多器官衰竭和严重致命COVID-19的发展相关 . 在我们的试播集里 实验结果表明,TNF-α + IL-6 + IL-1β + INF-γ联合作用可强烈诱导ACE 2的表达, 和TMPRSS 2在由原代人表皮角质形成细胞制成的3D人皮肤等同物(3D-HSE)中 (NHEK)。基于这些新的发现,我们假设发炎的皮肤可能被野生型SARS感染- CoV-2病毒及其新出现的突变变体,以及特定种族报告的较高感染率, 群体可能依赖于参与SARS-CoV-2细胞进入的蛋白质的较高表达水平。测试这些 假设,我们将使用含有假型刺突(S)蛋白的报告慢病毒,2D和3D-HSE 由用COVID相关细胞因子混合物预处理的AA、西班牙裔和WNH角质形成细胞制成的培养物- 19细胞因子风暴(TNF-α+IL-6+IL-1b+INF-γ)或经证实可诱导促银屑病的细胞因子(IL 17 + IL 22 + TNF α),或 在体外皮肤模型中的促特应性皮炎(IL 4 + IL 13)分子和形态学变化。
