We found that CatE deficiency had no effect on the expression of tissue‐type plasminogen activator (tPA), insulin‐degrading enzyme (IDE) Aβ‐degrading enzymes including neprilysin (NEP) and angiotensin‐converting enzyme (ACE) in the cortex and hippocampus of 6‐month‐old AD and AD/CatE−/− mice (Figure S2a,b). The gene discussed is CTSE; the disease is Alzheimer disease.
