Genetically Engineering a Susceptible Mouse Model for MERS-CoV-Induced Acute Respiratory Distress Syndrome 2019-09-14 .txt text/plain 6023 371 50 Precise molecular engineering of mouse DPP4 (mDPP4) with clustered regularly interspaced short palindromic repeats (CRISPR)/Cas9 technology maintained inherent expression profiles, and limited MERS-CoV susceptibility to tissues that naturally express mDPP4, notably the lower respiratory tract wherein MERS-CoV elicits severe pulmonary pathology. utilized a unique approach for producing susceptible mice that could replicate human isolates of MERS-CoV in the lungs by infecting mouse lungs with an adenovirus that constitutively expresses the full-length hDPP4 gene ( Fig. 1) [37] . Attempts to restrict hDPP4 expression to epithelial cells of the lungs using constitutive tissue specific promoters (e.g., cytokeratin K18) yielded outcomes similar to those observed with SARS-CoV mouse models, wherein high levels of MERS-CoV infection/replication were detected in the brains (Fig. 1 ) [39] . Elevated human dipeptidyl peptidase 4 expression reduces the susceptibility of hDPP4 transgenic mice to Middle East respiratory syndrome coronavirus infection and disease ./cache/cord-265380-2gs34xcw.txt ./txt/cord-265380-2gs34xcw.txt
