IMMUNOLOGY

Detailed explanation-1: -Antigens are any substances that the immune system can recognize and that can thus stimulate an immune response. If antigens are perceived as dangerous (for example, if they can cause disease), they can stimulate an immune response in the body.

Detailed explanation-2: -An antigen is a foreign substance that enters your body. This can include bacteria, viruses, fungi, allergens, venom and other various toxins. An antibody is a protein produced by your immune system to attack and fight off these antigens.

Detailed explanation-3: -Non-self-antigens include the antigen structures found on the surfaces of foreign bacteria, viruses, fungi, parasites, or other non-native biocompounds. The immune system relies on antibody-antigen binding and the binding of antigens with receptors on B or T Cells to recognize non-self-antigens within the body.

Detailed explanation-4: -Innate immune recognition is mainly based on a series of germ-line encoded receptors that have been selected by evolution to recognize nonself molecules present in microorganisms. Innate immunity also recognizes changes in our cells caused by infection, such as the lack or induction of self molecules.

Detailed explanation-5: -T cells – Immune cells that recognize specific antigens during antigen presentation; T cells are the major players in the immune system’s fight against cancer.

Detailed explanation-6: -Any substance that is recognised as foreign and is capable of triggering an immune response is called an antigen (non self)

Detailed explanation-7: -Antibodies are compounds of protein and sugar that circulate in the bloodstream. They are created by the immune system to fight germs and foreign substances. Antibodies can quickly detect germs and other potentially harmful substances, and then attach to them.
