Question

Oligosaccharide cell markers on the surface of the cell can be recognized by the immune system as "self" or "foreign". This distinction allows the immune system to target and destroy foreign cells or pathogens, while leaving host cells unharmed. Antibodies and T-cells play a role in this process, but the initial recognition is based on the presence or absence of specific oligosaccharide markers.
