The current COVID-19 pandemic, which continues to spread across the globe, is caused by severe acute respiratory syndrome coronavirus (SARS-Cov-2). Soon after the pandemic emerged in China, it became clear that the receptor-binding domain (RBD) of angiotensin-converting enzyme 2 () serves as the primary cell surface receptor for SARS-Cov-2. Subsequent work has shown that diabetes and hyperglycemia are major risk factors for morbidity and mortality in COVID-19 patients. However, data on the pattern of expression of on human pancreatic β cells remain contradictory. Additionally, there is no consensus on whether the virus can directly infect and damage pancreatic islets and hence exacerbate diabetes. In this mini-review, we highlight the role of receptor and summarize the current state of knowledge regarding its expression/co-localization in human pancreatic endocrine cells. We also discuss recent data on the permissiveness of human pancreatic β cells to SARS-Cov-2 infection.
当前的 COVID-19 大流行仍在全球范围内蔓延，它是由严重急性呼吸系统综合症冠状病毒 2 型（SARS-CoV-2）引起的。在中国出现大流行后不久，人们就清楚地认识到血管紧张素转化酶 2（ACE2）的受体结合域（RBD）是 SARS-CoV-2 的主要细胞表面受体。随后的研究表明，糖尿病和高血糖是 COVID-19 患者发病率和死亡率的主要危险因素。然而，关于 ACE2 在人胰腺β细胞上的表达模式的数据仍然存在矛盾。此外，关于该病毒是否可以直接感染和损伤胰岛并因此加重糖尿病，目前也没有共识。在这篇小型综述中，我们强调了 ACE2 受体的作用，并总结了目前关于其在人胰腺内分泌细胞中的表达/共定位的知识状况。我们还讨论了关于人胰腺β细胞对 SARS-CoV-2 感染易感性的最新数据。
