ACE2 is a cell-surface protein on lung cells in corona viral infected patientsAAK1 receptor promoted endocytosis involved in ACE2The study suggests the use of Baricitinib to inhibit AAK1 in patients with 2019-nCoV acute respiratory disease, to reduce both the viral entry and the inflammation in patients, using endpoints such as the MuLBSTA score, an early warning model for predicting mortality in viral pneumonia [58]. This evidence concerns the gene ACE2 and viral pneumonia.
