Synthesized proteins such as M, E, and S are entered into the endoplasmic reticulum (ER)-Golgi intermediate compartment (ERGIC) complex and make the structure of viral envelope.[22] On the other hand, the replicated genome binds to N protein and forms the ribonucleoprotein (RNP) complex. The outer cover is formed by the M, E, and S proteins.[22] Finally, the virus particle comes out of the ERGIC by making a bud-like structure.[23] These mature virions form a vesicle, which fuses with the plasma membrane and releases the virus particles into the extracellular region.[2324] The detailed structure of CoV and its life cycle is depicted in Figures 1 and 2. On infection, the SARS-CoV and MERS-COV cause a surge of pro-inflammatory cytokines and chemokines, which cause damage to lung tissue,[13] deterioration of lung function, and then finally lung failure in some cases.[25]
