Detailed explanation-1: -Antigens and antibodies play vital but distinct roles in illness and disease. One tries to wreak havoc on our health while the other fights to protect it. Simply put, antigens can make you sick, and antibodies are how your body defends itself against antigens.
Detailed explanation-2: -Any substance that causes the body to make an immune response against that substance. Antigens include toxins, chemicals, bacteria, viruses, or other substances that come from outside the body. Body tissues and cells, including cancer cells, also have antigens on them that can cause an immune response.
Detailed explanation-3: -Antigens are markers that tell your body that something is foreign. Your immune cells make antibodies to recognize and destroy harmful antigens. In fact, you can think of antigens as antibody generators. Antibodies are very specific to the antigens they recognize and destroy.
Detailed explanation-4: -Not all antigens are dangerous. You have millions of them on your own red blood cells. Your immune system learns to recognize these as safe, so it ignores them. That’s why it’s important for blood donors to “match” antigens with the recipient.
