When the antibodies in the patient's serum attack antigens on the erythrocytes in donor blood, this is known as red blood cell incompatibility. Patients should receive blood with the same ABO and Rh(D) classification. A and B are dissimilar antigens on the red cells. The immune system recognizes antigens as foreign. O cells do not have A or B antigens.
Antibodies can attack both extracellular and intracellular antigens.
Antibodies attach to antigens preventing them from attacking cells in the body. Antitoxins attack antigens and destroy them
Having AB blood means you already have both A and B antigens in your organisms, so you DON'T have the antibodies, the A antigen doesn't affect the AB recipient 'cause it doesn't consider it as foreign (it's the same for the B antigen)
Antigen is a substance that can induce the generation of antibodies, any substance that can induce immune response. Antibody is a protective protein produced by the body in response to an antigen.
Antibodies. Also, white blood cells attack foreign substances in the blood.
Your body uses antibodies to attack any harmful substances in your body. These harmful substances are called antigens.
Blood can either be A, B, AB or O.This is differentiated by the antigen proteins on the cell. A has a antigens, b has b antigens, o has none, and AB has a and b antigens. You body also makes antibodies against what it doesn't have. So in your case, you have both and therefore dont create a or b antibodies. This makes you a universal acceptor. However, you can only donate to other AB people because if you give you blood to an A person, there body will attack the B antigens on your blood and same goes for B people.
AB Neg is priorty followed by B Neg
Antigens are foreign proteins that your immune system can recognize as being harmful to your body, so it produces antibodies that memorize the antigen protein so it can launch an immune response if it ever again invades your body.
Plasma Cell initiate attacks against specific antigens. Plasma cells are B cells bearing specific antibodies for binding to a specific antigen.
We wouldn't be able to make antibodies to fight antigens(pretty much anything bad that enters our body and creates sickness). Bad bacteria and viruses and fungi would attack your body without anything stopping them.
Yes, anything that triggers your immune system to have a response would be considered an antigen. H1N1 is a virus that causes influenza, and the detection of the presence of the virus will cause our immune systems to attack it. The immune system creates antibodies which can grab antigens to flag them as targets and disable them, which are then attacked and destroyed by other cells from the immune system. Once the body has developed antibodies to match the antigens of a particular invader , the pattern of those antibodies is stored by the immune system, and duplicates can be readily produced to grab that invader, if it or one like it, is detected again. That is what gives you immunity.
