Microscopic features have been identified by researchers which make pathogen to be much more infectious when compared to SARS virus, thus serving in the form of drug targets. With Coronavirus infections rising at a steady pace across the globe, researchers have been trying to understand the exact cause for its spreading so quickly and easily. Structural and genetic evaluations have helped determine significant feature of this virus. On the surface is present Coronavirus Protein, which perhaps might explain as to why human cells are easily & quickly infected.
There are other groups trying to investigate the exact reasons for its spreading to human tissues, with cell membrane receptor. The virus protein as well as cell receptor provides drugs with potential targets, so as to block this pathogen. However, researchers conclude it to be too early for being right.
The key towards containing this virus and prevent such outbreak in the future is to understand how it transmits. Scientists have been trying to study Recombinant Coronavirus antigens, so as to come up with effective vaccines to cure this ailment. This new virus is found to spread easily when compared to SARS (severe acute respiratory syndrome) also considered to be a coronavirus. This new virus is known to have infected 10 times of the people contracted with SARS.
Spike protein is used by coronavirus for cell infection purpose. The cell membrane is bounded by this protein, a procedure that gets activated by particular cell enzymes. Evaluating the genome of the new virus has determined that the spike proteins of this type tend to differ from its close relatives. It clearly suggests that protein comes with a site that is host cell enzyme activated, referred to as furin.
It is quite significant since furin can be found in good number of human tissues. It also includes the small intestines, liver and lungs. The virus can be stated to have the potentiality to attack multiple organs simultaneously.
Few symptoms noticed in coronavirus affected people are explained by the findings like liver failure. According to leading scientists, coronaviruses along with SARS are bracketed within the same genus like that of the new virus and are not known to develop furin activation sites.
The virus is established by furin activation site quite different when compared to SARS with regards to its entering the human cells. Virus stability is possibly affected and so is its transmission. There are several articles published on COVID-19 antigens that are worth going through, so as to understand what it is all about, its impact and other detailed information.
Activation site also has been identified by various groups as enabling the virus in spreading quickly and efficiently among human beings. According to such groups, the sites can be found in various other viruses which are known to spread between people quite easily including severe strains related to influenza virus. Activation site on such viruses can be found on a specific protein referred to as haemagglutinin and not spike protein.

Taking extreme caution
There are many researchers who can be found to be extremely cautious when it comes to overstating activation site’s role to assist the new virus to spread easily and quickly. Still scientists are yet to understand if it is to be on a mass scale or not like the ones that had affected the world few centuries ago.
Few scientists are wary when it comes to comparing flu viruses with new coronaviruses with regards to furin activation sites. Flu viruses have on their surface haemagglutinin protein, which is not related or similar to coronavirus based spike protein.
Spanish flu pandemic of the 1918s is referred to as the deadliest flu virus, which is not known to have furin activation site.
Scientists are of the strong opinion that there will be required detailed studies in animal or cell models to test functionality of the activation site. They also add that Coronaviruses are quite unpredictable. Even proper hypothesis can at times go wrong. Teams have been testing Recombinant 2019 nCoV and trying to know how to modify or eliminate the site which has been affecting functionality of the spike protein.
The molecules blocking furin are looked into by the scientists and investing them to be possible therapies. However, progress as of date is slow due to the outbreak. Another feature has been identified by scientists which may explain the reason for human cells to be infected successfully, quickly and easily by the new coronavirus. Experiments conducted clearly show that the receptor is bound by the spike protein on human cells, referred to as ACE2 (angiotensin converting enzyme-2. This is considered to be 10 times much tighter when compared to spike protein found in SARS virus. Prolonged lock downs across the globe has helped the virus to be controlled.
