    Although mounting evidence demonstrated that pancreas is infected by SARS-CoV-2 the severity and pathophysiology of pancreatic COVID-19 disease are still unclear. Here we investigated the consequences of SARS-CoV-2 infection of the pancreas and the role of Placenta-associated protein-8 (PLAC8). Our data showed pancreatic damage in patients who died from COVID-19. Notably, circulating pancreatic enzymes stratified patients according to COVID-19 severity and outcome. PLAC8 expression was associated with SARS-CoV-2 infection in postmortem analysis of COVID-19 patients and functional assays demonstrated the requirement of PLAC8 in SARS-CoV-2 pancreatic infection. Full SARS-CoV-2 infectious virus revealed a requirement of PLAC8 for efficient viral infection of pancreatic cell lines. Finally, we observed colocalization of PLAC8 and SARS-CoV-2 in the pancreas of deceased patients. In conclusion, our data confirm the human pancreas as a SARS-CoV-2 target and demonstrate the requirement of PLAC8 for SARS-CoV-2 pancreatic infection thereby opening new target opportunities for COVID-19-associated pancreatic pathogenesis.N
