Quotes About Antibodies

There are two main types of immunity to an infection. Innate immunity comes from circulating cells that attack any invader the body views as foreign. Adaptive immunity is specific to the pathogen presented. Through adaptive response, immune cells are programmed to secrete antibodies that are primed to target a viral invader.

When a person tests positive for HIV, it is not a test for the virus itself but for antibodies to the virus, and the test is not able to distinguish between HIV antibodies and a multitude of other antibodies. Many conditions can lead to a false positive result, including flu shots, hepatitis, and pregnancy.

After it defeats an infection, specialized white cells (called "memory T cells") and antibodies that bind to the antigen remain in the body. If any invader carrying the same antigen attacks again, the immune system responds far more quickly than the first time. When the immune system can respond so quickly that a new infection will not even cause symptoms, people become immune to the disease.

and of AIDS. The virus too small to imagine travelling through our fluids, even a drop or two of saliva or cunt slime, and unlocking our antibodies with its little picks, so that our insides lose their balance and we topple into pneumonia, into starvation. Love and death, they can't be pried apart anymore.

The B cells came from bone marrow and generated antibodies. The T cells matured in the thymus and could either fight or direct action. They are generals and soldiers.

The elderly tend to get fewer colds than kids, even though they have a weakened immune system. This happens because our systems develop defenses against antigens; we acquire antibodies to the germs we've defeated in the past (stored in plasma cells in your bone marrow, as mentioned earlier in Chapter 6), and destroy those antigens and viruses before they can multiply and cause that illness.

When a person tests positive for HIV, it is not a test for the virus itself but for antibodies to the virus, and the test is not able to distinguish between HIV antibodies and a multitude of other antibodies. Many conditions can lead to a false positive result, including flu shots, hepatitis, and pregnancy.

In a classic study published in 1992, the New England Journal of Medicine reported an important breakthrough about where these antibodies may be coming from. Researchers had taken blood samples from 142 children with type 1 diabetes. Every single child had antibodies to proteins in cow's milk. Further study showed that these antibodies were capable of attacking the insulin-producing cells of the pancreas.
