Glomerular and tubulointerstitial phosphorylated signal transducer and activator of transcription 3 (p-STAT3) expression in normal and COVID-19-associated AKI kidney. Normal and non-COVID-19 autopsy kidney shows a small amount of p-STAT3 (both Tyr705 and Ser727) positive staining in glomeruli, tubules and interstitium. Compared with normal kidney and non-COVID-19 autopsy kidney, there was an increase in glomerular and tubulointerstitial p-STAT3 (Tyr705) and p-STAT3 (Ser727) staining in kidney from cases with COVID-19-associated AKI kidney
