Summary
The MNS blood group system now includes three new antigens (MNS47-49), bringing the total to 49. This update also details new glycophorin variants and associations with band 3, Rh proteins, and malaria.
Area of Science:
- Immunology
- Genetics
- Hematology
Background:
- The MNS blood group system is a complex human blood group system.
- Previous reviews have detailed its known antigens and genetic basis.
Purpose of the Study:
- To provide an update on the MNS blood group system.
- To report newly identified antigens and variants.
- To present findings on associations with other blood group proteins and diseases.
Main Methods:
- Literature review and analysis of new studies.
- Characterization of novel glycophorin (GP) variants.
- Investigation of antigen associations with band 3 and Rh proteins.
- Exploration of MNS antigen links to malaria.
Main Results:
- Three new MNS antigens (MNS47, MNS48, MNS49) have been identified.
- New glycophorin (GP) variants exhibiting silent or weak MNS antigen expression were discovered.
- New data on associations between MNS antigens, band 3, Rh proteins, and malaria were reported.
- The total number of antigens in the MNS system increased to 49.
Conclusions:
- The MNS blood group system continues to expand with new antigen discoveries.
- Understanding MNS variants and associations is crucial for transfusion medicine and disease research.
- Further research is warranted to fully elucidate the clinical significance of these findings.

01:29Blood Flow
75.7K
Blood is pumped by the heart into the aorta, the largest artery in the body, and then into increasingly smaller arteries, arterioles, and capillaries. The velocity of blood flow decreases with increased cross-sectional blood vessel area. As blood returns to the heart through venules and veins, its velocity increases. The movement of blood is encouraged by smooth muscle in the vessel walls, the movement of skeletal muscle surrounding the vessels, and one-way valves that prevent backflow.

The blood in our bodies comprises three major components: blood plasma, formed elements, and the extracellular matrix. Blood plasma is a yellowish fluid that constitutes 55% of the total blood volume. It is primarily made up of water and essential substances such as electrolytes and proteins. Blood plasma serves as a medium for transporting blood cells and also contains nutrients, enzymes, hormones, antibodies, and gases.
Formed elements constitute the remaining 45% of the blood volume. These...

02:20Blood Types
22.4K
Human blood is classified into different types based on the presence of antigens on the red blood cell's surface and antibodies in the plasma. Proper identification of blood type is essential for successful blood transfusion. The International Society of Blood Transfusion has identified 38 human blood types based on the surface antigens on the red blood cells. The most common types are ABO, Rh, and MNS blood types.

The ABO blood group system is a critical element of transfusion medicine, essential for determining blood compatibility in transfusions and organ transplants. It is based on specific antigens, or agglutinogens, present on the surface of red blood cells (RBCs) and corresponding antibodies, or agglutinins, in the blood plasma.

Understanding an individual's blood group is a critical component of transfusion medicine. It ensures compatibility in blood transfusions, organ transplants, and even during pregnancy. Determining these blood groups involves the ABO and Rh blood typing systems, utilizing specific antigens and corresponding anti-sera to identify an individual's blood type.
