Immunologic surface markers, also known as cell surface markers or cell surface antigens, are proteins that are expressed on the outer surface of cells and play a crucial role in identifying and classifying different cell types within the immune system. These markers are used to distinguish one type of cell from another, allowing for precise identification, characterization, and tracking of various immune cells.
Immunologic surface markers are typically classified into different clusters of differentiation (CD) groups, each representing a specific protein marker on the cell surface. Through the use of specific antibodies designed to bind to these markers, researchers and clinicians can analyze and manipulate immune cell populations for various purposes, such as diagnosis, treatment, and immunotherapy.
These markers are particularly useful in immunology research and clinical applications, as they enable the identification and isolation of specific immune cells involved in immune responses, such as T cells, B cells, natural killer cells, and dendritic cells. By studying the presence or absence of specific markers on these cells, scientists can gain insights into their function, activation status, and interactions with other cells of the immune system.
In summary, immunologic surface markers are proteins expressed on the outer surface of immune cells that help identify and distinguish different cell types within the immune system. They play a crucial role in the study and manipulation of immune cells, contributing to our understanding and advancement in various areas of immunology and medicine.
