cell surface antigen
1Cell surface receptor — The seven transmembrane α helix structure of a G protein coupled receptor Cell surface receptors (membrane receptors, transmembrane receptors) are specialized integral membrane proteins that take part in communication between the cell and the… …
2cell-surface marker — an antigenic determinant occurring on the surface of a specific type of cell. Schematic drawing of cell surface markers on human B and T cells, each marker specific for a different antigen …
3Proliferating cell nuclear antigen — The assembled human DNA clamp, a trimer of the protein PCNA …
4Antigen processing — is a biological process that prepares antigens for presentation to special cells of the immune system called T lymphocytes. This process involves two distinct pathways for processing of antigens from an organism s own (self) proteins or… …
5Antigen presentation — is a process in the body s immune system by which macrophages, dendritic cells and other cell types capture antigens and then enable their recognition by T cells. NOTOC The basis of adaptive immunity lies in the capacity of immune cells to… …
6antigen-presenting cell — n any of various cells (as a macrophage or a B cell) that take up and process an antigen into a form that when displayed at the cell surface in combination with a molecule of the major histocompatibility complex is recognized by and serves to… …
7Cell adhesion molecule — Cell Adhesion Molecules (CAMs) are proteins located on the cell surface[1] involved with the binding with other cells or with the extracellular matrix (ECM) in the process called cell adhesion. These proteins are typically transmembrane receptors …
8cell-bound antibody — cell fixed antibody any antibody bound to a cell surface either by its antigen combining sites to cell surface antigenic determinants or by other sites to specific cell surface receptors (Fc receptors, IgE receptors) …
9Antigen — Each antibody binds to a specific antigen; an interaction similar to a lock and key. An antigen is a foreign molecule that, when introduced into the body, triggers the production of an antibody by the immune system. The immune system will then… …
10Cell adhesion — Cellular adhesion is the binding of a cell to a surface, extracellular matrix or another cell using cell adhesion molecules such as selectins, integrins, and cadherins. Correct cellular adhesion is essential in maintaining multicellular structure …
