Kolhydratantigener

Kolhydratantigener are molecules found on the surface of cells, particularly in red blood cells. They are composed of carbohydrate chains linked to proteins or lipids. These antigens play a crucial role in the immune system, acting as markers that the body recognizes as either self or non-self. The most well-known examples are the ABO blood group antigens, which determine a person's blood type. These antigens are inherited and are responsible for the compatibility or incompatibility of blood transfusions. If incompatible blood types are mixed, the recipient's immune system can mount a severe reaction against the transfused red blood cells. Beyond the ABO system, there are numerous other carbohydrate antigen systems, many of which are still being investigated for their significance in various biological processes and disease states. Their presence can also be influenced by certain medical conditions and pathogens.
