CDL Antigen refers to the Cluster of Differentiation (CD) molecules expressed on the surface of cells. CD molecules are proteins or glycoproteins that play a crucial role in immune system functions, particularly cell recognition and communication. CD molecules are used to categorize and identify various cell types, including immune cells, by their distinct surface markers.
The CDL Antigen is a broad term that includes a vast array of CD molecules. Each CD molecule is assigned a number (CD1, CD2, CD3, etc.) to distinguish it from other CD molecules. These antigens are found on different cell types, including T cells, B cells, natural killer cells, and other immune cells. CD molecules are essential for the immune system's ability to recognize foreign invaders such as bacteria, viruses, and abnormal cells.
CDL Antigens are involved in various immune responses, including cell adhesion, cell signaling, and immune cell activation. They also serve as receptors for certain ligands in immune reactions. By interacting with other cells or molecules, CDL Antigens facilitate immune cells' recruitment, migration, and differentiation.
The identification and characterization of CDL Antigens are crucial in immunology research and clinical applications. Scientists and healthcare professionals rely on the specific recognition patterns and expression levels of CD molecules to differentiate between cell populations, diagnose diseases, and determine treatment strategies. Additionally, CDL Antigens provide valuable insights into the understanding of immune system dysfunctions and the development of targeted immunotherapies.
