Coronavirus envelope protein. The envelope (E) protein is the smallest and least well-characterized of the four major structural proteins found in coronavirus virions. [ 2 ][ 3 ][ 4 ] It is an integral membrane protein less than 110 amino acid residues long; [ 2 ] in SARS-CoV-2, the causative agent of Covid-19, the E protein is 75 residues long ...
The SARS-related coronavirus is an enveloped, positive-sense, single-stranded RNA virus. Its genome is about 30 kb, which is one of the largest among RNA viruses. The virus has 14 open reading frames which overlap in some cases. [ 19 ] The genome has the usual 5′ methylated cap and a 3′ polyadenylated tail. [ 20 ]
The authors conclude that damage to the brainstem associated with infection may help explain some of the symptoms of long COVID. Following infection with SARS-CoV-2, the virus that causes COVID-19 ...
The mRNA COVID-19 vaccines do this by causing the body to create a piece of a protein similar to one found in the coronavirus. (The protein that the body creates in response to the mRNA vaccine is ...

[ 2 ][ 3 ] This usually takes the form of a bone marrow or peripheral blood stem cell transplantation, but the cells can also be derived from ...
The authors came to the conclusion that no further trials of hydroxychloroquine or chloroquine for treatment of COVID-19 should be carried out.
