-Viruses can come in many shapes and sizes.

-The main role/job of a virus is to deliver its DNA or RNA genome into the host cell it is infecting.

-A virus can not reproduce outside it's host.

-Viruses can infect people through the nose, mouth or breaks in the skin.

-An antibody can attach itself onto some viruses and follow them on their path to infecting a cell.

-Once the virus enters the cell, antibodies can trigger an immune response while inside the cell, killing the virus without damaging the cell.

-When scientist increased the amount of TRIM21 in the cell, the destruction would happen quicker and more easily.

-Once an antibody targets a specific virus it will only target that virus.

-There has been a recent discovery that an antibody that can kill HIV.

-The only downside with this discovery is that the antibody is created 5 or more years after HIV infects the body.

After an antibody kills the virus it is tracking, it looks for another virus of that same type to track and kill.

Once a virus is programmed to track a type of virus it always tracks that kind of virus because our body can make so many types of antibodies to track and kill countless amounts of viruses.
