Understanding Kell Proteins and Their Role in the Immune System

Kell is a type of protein that is found in the blood. It is also known as CD46, and it plays an important role in the immune system.

Kell proteins are found on the surface of red blood cells, and they help to regulate the immune response by interacting with other immune cells and molecules. They can also act as a receptor for certain viruses, such as the human immunodeficiency virus (HIV), which can infect red blood cells.

There are several different types of Kell proteins, each with its own specific functions and properties. Some Kell proteins are more common in certain populations or geographic regions, and they may be associated with certain diseases or conditions.

Kell proteins are named after the Kell blood group, which is a group of antigens that are found on the surface of red blood cells. The Kell blood group is one of the most complex blood groups, with many different antigens and subtypes.

Overall, Kell proteins are an important part of the immune system, and they play a key role in regulating the immune response and protecting against infection.
