    COVID-19 MESHD morbidity and mortality is significantly increased in patients with diabetes MESHD and kidney disease MESHD via unknown mechanisms. SARS-CoV-2 uses angiotensin-converting enzyme 2 (ACE2) for entry into human host cells, and ACE2 levels in target cells may influence SARS-CoV-2 susceptibility. We investigated how pre-existing conditions and drug treatments alter receptor expression in kidney tissue. Using single cell RNA profiling (scRNAseq) to assess ACE2 and associated SARS-CoV-2 proteases in healthy living donors (LD) kidneys, diabetic kidney disease MESHD ( DKD MESHD), and in kidney injury MESHD during viral infection MESHD, ACE2 expression was primarily associated with proximal tubular epithelial cells (PTEC). ACE2 mRNA expression levels were significantly upregulated in DKD MESHD versus LD, however, ACE2 levels were not altered by exposures to renin angiotensin aldosterone system (RAAS) inhibitors. ACE2+ expression signatures were defined by differential expression analysis and characterized by Bayesian integrative analysis of a large compendium of public -omics datasets, resulting in the identification of network modules induced in ACE2 positive PTEC in DKD MESHD and BK virus nephropathy MESHD nephropathy HP. These ACE2 upregulated cell programs were linked to viral entry, immune activation, endomembrane reorganization, and RNA processing and overlapped significantly with the cellular responses induced by SARS-CoV-2 infection MESHD. Similar cellular programs were activated in ACE2-positive PTEC isolated in a urine sample from a COVID19 MESHD patient with acute kidney injury HP acute kidney injury MESHD, suggesting a consistent ACE2-coregulated expression program that may interact with SARS-Cov-2 infection MESHD processes. The SARS-CoV-2 receptor associated gene signatures could seed further research into therapeutic strategies for COVID-19 MESHD. Functional networks of gene expression signatures are available for further exploration to researchers at HumanBase (hb.flatironinstitute.org/covid-kidney).
