Detailed explanation-1: -T cells can detect the presence of an intracellular pathogen because infected cells display on their surface peptide fragments derived from the pathogen’s proteins. These foreign peptides are delivered to the cell surface by specialized host-cell glycoproteins.
Detailed explanation-2: -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-3: -Immune markers are proteins that determine our ability to resist harmful agents such as bacteria and other foreign substances.
Detailed explanation-4: -It can tell the difference between the body’s own cells and those belonging to invaders. Immune system cells can tell the difference between “self” and “non-self.” Each and every cell in our body carries special marker molecules. These markers are also called antigens.
