To elucidate the transcriptional characteristics of COVID-19. We utilized an integrative approach to comprehensively analyze the transcriptional features of both COVID-19 patients and SARS-CoV-2 infected cells. Widespread infiltration of immune cells was observed. We identified 233 genes that were codifferentially expressed in both bronchoalveolar lavage fluid and lung samples of COVID-19 patients. Functional analysis suggested upregulated genes were related to immune response such as neutrophil activation and antivirus response, while downregulated genes were associated with cell adhesion. Finally, we identified , and as core genes during SARS-CoV-2 infection. The identification of core genes involved in COVID-19 can provide us with more insights into the molecular features of COVID-19.
为了阐明 COVID-19 的转录特征。我们采用了一种综合的方法来全面分析 COVID-19 患者和 SARS-CoV-2 感染细胞的转录特征。观察到免疫细胞广泛浸润。我们在 COVID-19 患者的支气管肺泡灌洗液和肺组织样本中鉴定出 233 个差异表达的基因。功能分析表明，上调的基因与免疫反应有关，如中性粒细胞的激活和抗病毒反应，而下调的基因与细胞黏附有关。最后，我们鉴定出、和在 SARS-CoV-2 感染过程中的核心基因。鉴定出 COVID-19 相关的核心基因可以使我们更深入地了解 COVID-19 的分子特征。
