Cluster of differentiation (CD) markers

Cluster of Differentiation (CD) markers are specific molecules found on the surface of immune cells. They act like identification tags, helping cells recognize and communicate with each other. These markers are used by scientists and doctors to identify different types of immune cells, understand immune responses, and diagnose certain diseases. Each CD marker has a unique shape or structure, which allows it to serve specific functions within the immune system, such as activating cells or signaling other parts of the body. In essence, CD markers are essential tools for understanding how our immune system identifies and responds to threats.
