When tissue is attacked by a virus, the virus enters the cells and hijacks the cell's machinery to replicate itself. This process often damages the infected cells, leading to inflammation and immune responses that can cause further tissue damage. Ultimately, the tissue may become weakened or die, resulting in symptoms of infection.

What tissue allows osmosis and diffusion to happen?

Simple squamous epithelial tissue allows osmosis and diffusion to happen due to its thin and permeable nature. It allows for the movement of molecules across the tissue through passive processes like osmosis and diffusion.


What is glycoproteins do in virus?

Glycoproteins play a crucial role in virus entry into host cells by facilitating attachment and fusion with the cell membrane. They also help in evading the host immune system by shielding the virus from detection and destruction. Additionally, glycoproteins can determine the host range and tissue tropism of the virus.


How can a virus destroy cells?

A virus can destroy cells by invading them, using the cellular machinery to replicate, and eventually causing cell death. This process can disrupt normal cell function and lead to tissue damage and inflammation.


What determines a virus's tissue tropism?

What cellular receptors that reacts with the viruses surface proteins which in turn can facilitate internalization to the cell usually determines the tissue tropism. This is a biological principle which occurs for example with most of the bodys hormones. The main thought here is that the viral surface proteins is like a key, and the cell kan have many kinds of different locks which may open the door to the cell. Once inside the cell, the virus must also avoid setting off the cells "alarm system" which may cause apoptosis (programmed cell death) or trigger the immune system which ends up getting the cell, and the virus contained. If a virus can get into the cell and also not get discovered, its likely to establish an infection in this cell. There are of course exceptions to what is mentioned above, and different strategies of infection making it hard to define, but the main principle remains the same.


How are virus cultured?

Viruses can be cultured in tissue or cell media.
