TLDR
It is found that SARS-CoV-2 replication induces a delayed interferon (IFN) response in lung epithelial cells and that IRF-3, -5, and NF-kB/p65 are the key transcription factors regulating the IFN response during Sars-Cov-2 infection.

A pneumonia outbreak associated with a new coronavirus of probable bat origin

TL;DR: Identification and characterization of a new coronavirus (2019-nCoV), which caused an epidemic of acute respiratory syndrome in humans in Wuhan, China, and it is shown that this virus belongs to the species of SARSr-CoV, indicates that the virus is related to a bat coronav virus.
