Corona Virus Infecting Cells

After entering the body in the case of coronavirus this is thought to occur through the nose mouth or eyes a virus attaches itself to a host cell and inserts its genetic instructions. The coronavirus has already been known to enter human cells by binding to a protein on the cell surface called ace2.

These cells normally develop into respiratory tract cells lined with hair like.

Corona virus infecting cells. The virus infects the cell by fusing its oily membrane with the membrane of the cell. Researchers led by qiang zhou. For the study the researchers compared levels of ace2 in the lungs kidneys.

The receptor binding domain rbd is loosely attached among virus therefore the virus may infect multiple hosts. Using existing data on the rna found in different types of cells the researchers were able to search for cells that express the two proteins that help the sars cov 19 virus enter human cells. Scientists have revealed the first picture of how the new coronavirus sars cov 2 binds with human respiratory cells in order to hijack them to produce more viruses.

Once inside the coronavirus releases a snippet of genetic material called rna. They found subsets of cells in the lung the nasal passages and the intestine that express rna for both of these proteins much more than other cells. The glycoprotein spikes on the outer surface of coronaviruses are responsible for the attachment and entry of the virus to host cells fig.

The virus can then hijack the host cell s functions to produce the components needed for it to create copies of itself. They discovered that the receptor for this coronavirus is abundantly expressed in certain progenitor cells.
