摘要:

目的 检测SARS冠状病毒(SARS-CoV)S蛋白的功能性受体血管紧张素转换酶2(ACE2)在小鼠胰腺内、外分泌腺的表达。方法 ① RT-PCR:麻醉小鼠后取胰腺和肺组织,采用RTPCR方法检测各组织ACE2的表达。② 免疫电镜:麻醉小鼠后取胰尾,采用免疫电镜方法检测胰腺组织ACE2的表达。结果 胰腺和肺脏组织均表达ACE2 mRNA,且胰腺内、外分泌腺均表达ACE2。结论 ACE2在小鼠胰腺内、外分泌腺的表达可介导SARS-CoV侵入并损害胰腺,使胰岛素耗竭。

Abstract:

Objective This study was designed to investigate the expression of angiotensin-converting enzyme 2(ACE2) in endocrine and exocrine tissue of mouse pancreas. Methods The expressions of ACE2 in mouse pancreas was detected by reverse transcriptase polymerase chain reaction(RT-PCR) and the expressions of ACE2 in mouse pancreas was detected by immunoelectron microscopy. Results The expression of ACE2 mRNA was detected in whole mouse pancreas and lung tissues, while ACE2 protein was detected in both endocrine tissue and exocrine tissue of mouse pancreas. Conclusion These data demonstrated a tissue specific pattern of ACE2 expression in mouse pancreas and this indicated ACE2 might be present in islet of pancreas of human. Since ACE2 works as a negative regulator of the angiotensin system, the expression of ACE2 protein in endocrine tissue of pancreas may give us more clue for the treatment of diabetes.
