Question

Which ICAM is found only on red cells and has been known for a long time as the Landsteiner-Wiener blood group antigen?

a) ICAM-1
b) ICAM-2
c) ICAM-3
d) ICAM-4
e) ICAM-5

Answer 1

The ICAM known as the Landsteiner-Wiener blood group antigen is ICAM-4, which is a protein-based antigen present on red blood cells.

Step-by-step explanation:

The ICAM found only on red cells and known as the Landsteiner-Wiener blood group antigen is ICAM-4. This antigen is identified based on antigens made of proteins, specifically glycolipids and glycoproteins, which are found on the surface of red blood cells. The knowledge of blood group antigens has been crucial for ensuring safe blood transfusions by matching patient and donor blood types to prevent transfusion reactions and deaths.

The ICAM found only on red cells and known as the Landsteiner-Wiener blood group antigen is ICAM-4. It is based on antigens made of proteins, specifically glycolipids and glycoproteins, found on the surface of red blood cells. This antigen helps identify red blood cells as part of the body and prevents them from being attacked by antigens within the blood.
