Castleman disease; cluster of differentiation; communicable disease; contagious disease; curative dose.
Symbol for the element cadmium.
A cell adhesion molecule found on the surface of natural killer cells and T cells that is critical for stabilizing contacts between T cells and antigen-presenting cells. It is used clinically as a biomarker in the laboratory evaluation of some leukemias and lymphomas. SEE: cluster of differentiation.
One of a group of proteins on the surface of lymphocytes that enhance immune recognition. Immune cells that express the CD4 molecule are also known as helper T cells; they work with cells that express major histocompatibility complex (MHC) class II molecules to recognize antigens and stimulate cell-mediated and humoral immune responses. The human immunodeficiency virus (HIV) uses the CD4 receptor to infect T lymphocytes, macrophages, and other immunologic cells. SEE: AIDS; cluster of differentiation.
An immunoglobulin embedded within a cell membrane, expressed on the surface of mature T lymphocytes and thymocytes. SEE: cluster of differentiation.
An antigenic protein found only on the surface of B lymphocytes. It can be used to identify and separate those cells from others and can be exploited as a target for monoclonal antibody therapy. Monoclonal antibodies that block CD20 include rituximab and ofatumumab.
The interleukin-2 receptor.
A membrane-bound cell surface antigen present on and identifying T cells, monocytes, and macrophages. It is found principally on endothelial cells and blood-forming stem cells, and regulates cell-to-cell adhesion.
A cell surface glycoprotein heavily expressed by several blood and lymphatic cancers. SEE: cluster of differentiation.
A cell surface antigen expressed on many natural killer cells. SEE: cluster of differentiation.
A glycoprotein expressed on monocytes and tissue macrophages. SEE: cluster of differentiation.
A cell surface glycoprotein used in immunohistochemistry to identify monocytes and macrophages. SEE: cluster of differentiation.
