Reply to comment by mentalhelpneeded247 in Do all humans have the same antigens? Or are the antigens in the body the same for everybody? by menooby

Antigen-specific antibodies are produced by the immune system in response to the presence of a specific antigen, such as a virus or bacteria. The production of antibodies is a natural process that helps the body to defend itself against infection and disease. Some of the antibodies produced in response to an antigen will remain in the body for a long time, providing ongoing protection against future exposures to the same antigen. Other antibodies may not persist for as long and may be cleared from the body over time. The length of time that an antibody remains in the body can depend on a variety of factors, including the specific characteristics of the antigen and the immune system of the individual.

But it’s so interesting that some go and some stay. Is it because our cells can only hold so much “data”?

Thanks for all the assist on answering these questions! I was not fully committed to breaking down MHC proteins and how antibodies are made. Immunology isn’t my biomedical subject specialty.
