For example, reports of new-onset diabetes in patients suffering from COVID-19 led to the speculation that the pancreas is a possible target for SARS-CoV-2, yet a co-expression of ACE2 and TMPRSS2 was not found within pancreatic ß-cells, and ACE2 had a broader tissue expression than TMPRSS2 [59]. This evidence concerns the gene TMPRSS2 and COVID-19.
