The influence of interferon-lambda on restricting Middle East Respiratory Syndrome Coronavirus replication in the respiratory epithelium.

ABSTRACT: Middle East Respiratory Syndrome Coronavirus (MERS-CoV) causes severe respiratory in human with high mortality and it has been a challenge to determine optimum treatment for MERS-CoV-induced respiratory infection. Here, we observed the distribution of MERS-CoV receptors using human respiratory mucosa and also evaluated the contribution of interferon-lambdas (IFN-λs) in response to MERS-CoV infection using in vitro normal human nasal epithelial (NHNE) and bronchial epithelial (NHBE) cells. We found that the gene and protein expression of DPPIV, MERS-CoV receptor, were more dominantly located in nasal and bronchial epithelium although human nasal mucosa exhibited relatively lower DPPIV expression than lung parenchymal tissues. The quantitative mRNA level of the MERS-CoV envelope (upE) gene w
