Abstract

Purpose: To investigate the transcriptome of human bronchial epithelial cells (HBEC) in response to serum from patients with different degrees of inflammation.

Methods: Serum from 19 COVID-19 patients obtained from the Hannover Unified Biobank was used. At the time of sampling, 5 patients had a WHO Clinical Progression Scale (WHO-CPS) score of 9 (severe illness). The remaining 14 patients had a WHO-CPS of below 9 (range 1-7), and lower illness. Multiplex immunoassay was used to assess serum inflammatory markers. The culture medium of HBEC was supplemented with 2% of the patient's serum, and the cells were cultured at 37 °C, 5% CO₂ for 18 h. Subsequently, cellular RNA was used for RNA-Seq.

Results: Patients with scores below 9 had significantly lower albumin and serum levels of E-selectin, IL-8, and MCP-1 than patients with scores of 9. Principal component analysis based on 500 "core genes" of RNA-seq segregated cells into two subsets: exposed to serum from 4 (I) and 15 (II) patients. Cells from a subset (I) treated with serum from 4 patients with a score of 9 showed 5566 differentially expressed genes of which 2793 were up- and 2773 downregulated in comparison with cells of subset II treated with serum from 14 patients with scores between 1 and 7 and one with score = 9. In subset I cells, a higher expression of TLR4 and CXCL8 but a lower CDH1, ACE2, and HMOX1, and greater effects on genes involved in metabolic regulation, cytoskeletal organization, and kinase activity pathways were observed.

Conclusion: This simple model could be useful to characterize patient serum and epithelial cell properties.

人类支气管上皮细胞转录组对不同炎症状态患者血清的反应变化

目的：研究人类支气管上皮细胞（HBEC）对不同炎症程度患者血清反应的转录组：方法：使用从汉诺威统一生物库（Hannover Unified Biobank）获得的 19 名 COVID-19 患者的血清。采样时，5 名患者的 WHO 临床进展量表（WHO-CPS）评分为 9（重症）。其余 14 名患者的 WHO-CPS 评分低于 9（范围为 1-7），病情较轻。采用多重免疫测定法评估血清炎症指标。在 HBEC 培养液中添加 2% 的患者血清，在 37 °C、5% CO2 条件下培养细胞 18 小时，然后将细胞 RNA 用于 RNA-Seq 分析：基于 500 个 RNA-Seq "核心基因 "的主成分分析将细胞分为两个子集：暴露于血清的 4 个子集（I）和 15 个子集（II）。与用 14 名患者血清（得分在 1-7 之间，其中一名患者得分 = 9）治疗的子集 II 细胞相比，用 4 名患者血清（得分 9）治疗的子集 I 细胞有 5566 个差异表达基因，其中 2793 个基因上调，2773 个基因下调。在子集 I 细胞中，观察到 TLR4 和 CXCL8 的表达较高，但 CDH1、ACE2 和 HMOX1 的表达较低，参与代谢调节、细胞骨架组织和激酶活性途径的基因受到的影响较大：这种简单的模型可用于描述患者血清和上皮细胞的特性。
