Protein 'peptide' can stop Covid-19 from spreading in the body

MIT scientists have developed a peptide that can prevent coronaviruses from spreading in the body.


Researchers at the Massachusetts Institute of Technology (MIT) are testing a piece of protein on a 'peptide' that may prevent the coronavirus covid-19 from entering lung cells.  This drug can be helpful in dealing with covid-19.  According to scientists, this drug is a small piece of protein called a peptide, which looks like a protein found on the surface of human cells.  According to him, this peptide can inhibit the viral protein that coronaviruses use to enter human cells.  With this help, the coronavirus can be stopped before it spreads in the body.  Brad Pentelute, associate professor of chemistry at MIT, who is also leading this research, pointed out that this is a compound we were looking for, because it is reacting with proteins related to the coronavirus in the same way as we did about it.  I thought  This is the reason why with its help the coronavirus can be prevented from entering the cell.  Researchers have sent peptide samples to be tested on human cells.  Preliminary findings related to this research being conducted by MIT have been put on an online preparation server, Biorexiv, on 20 March.  However, it has not yet been reviewed by scientists or medical experts.

How does Covid-19 attack human body

The Pentelute Lab started working on the project since early March.  Ever since it has been discovered, the virus attaches to the cells of the sick person through its trimeric spike glycoprotein.  Also in that research, it was discovered that Kovid-19 sticks to host cells 10 times more strongly than SARS virus.  It also revealed that the virus attaches to a 'receptor' in a specific part of the host.  This receptor is found on the surface of human cells, including the lungs.

How does this peptide compete with Covid-19


Knowing this, with the help of simulations in Pentelute's lab, the location was found where the coronavirus attaches itself to the host cell's receptor with the help of glycoproteins.  Also it came to know how these two react with each other.  Knowing this, the lab used peptide synthesis technology to deal with it, which they had already developed.  With this, they produced a peptide that could bind the glycoprotein of this virus.  Also, how strongly it can stop it, it has also been investigated.  To understand this, he has created more than 100 types of peptides.  Regarding this, Professor Pentelute said that we are confident that we really know where these molecules react in the body.  With the help of this information, we can prevent this virus from entering the body.  Significantly, the researchers have sent that peptide to the lab where it can be tested on human cells and animals infected with Kovid-19.  They believe that peptides have large molecules, so they can hold onto the coronavirus and prevent it from entering the cells.  Whereas if you use a small molecule, it is not able to block the entire area of ​​the virus.  However, the antibodies also have larger surfaces, so they can also prove useful in preventing this.  But the biggest problem in that is that they take more time to search and manufacture.  While such drugs have the advantage that they are relatively easy to manufacture in large quantities.

 The biggest drawback of peptide drugs is that they usually cannot be eaten directly, they have to be injected into the body.  Also, there is a need to make changes in it so that it can stay in the blood longer and be more effective.  Currently the lab is also working on it.  According to Professor Pentelute "It is difficult to predict how long we will be able to test this drug on patients. But my aim is to do it in the next few weeks."  Worldwide, this virus has caught more than 6 lakh people, with it 27,456 people have lost their lives so far.  In such a situation, if there is no medicine to deal with it soon, then the figures of those who die from it can be many times more.
