IGG RECEPTORS Meaning and
Definition
-
IgG receptors, also known as Fc gamma receptors, are a group of cell surface proteins that specifically bind to the Fc region of immunoglobulin G (IgG) antibodies. IgG receptors play a crucial role in the immune response by mediating various functions of IgG antibodies.
These receptors are mainly found on the surface of cells that are involved in the immune system, such as macrophages, neutrophils, natural killer cells, and dendritic cells. Once an IgG antibody is bound to its specific antigen, the Fc region of the antibody becomes accessible for interaction with the IgG receptor on the immune cell surface.
The binding of IgG antibodies to their receptors triggers a cascade of immune responses, including phagocytosis, antibody-dependent cellular cytotoxicity, and the release of inflammatory molecules. This interaction between IgG and its receptors allows immune cells to identify, target, and eliminate pathogens, infected or cancerous cells, and other foreign substances.
There are several types of IgG receptors, including FcγRI (CD64), FcγRII (CD32), and FcγRIII (CD16), which are categorized based on their structure, affinity for IgG subclasses, and immune cell distribution. These receptors vary in their effector functions and activation thresholds, ensuring a diverse and tailored immune response.
In summary, IgG receptors are cell surface proteins that specifically bind to the Fc region of IgG antibodies, enabling the recruitment and activation of immune cells for the elimination of pathogens and other foreign substances.

Etymology of IGG RECEPTORS
The term "IgG receptors" is derived from the combination of two key components: "IgG" and "receptors".
1. IgG: IgG stands for Immunoglobulin G, which is a type of antibody found in the human immune system. Antibodies are proteins produced by the immune system in response to the presence of foreign substances called antigens. IgG is the most abundant type of antibody in the human body and plays a vital role in immune response, including recognizing and neutralizing pathogens and activating other components of the immune system.
2. Receptors: Receptors are proteins found on the surface of cells that facilitate communication and interaction with other molecules. They act as molecular "locks" that specific molecules, such as hormones, neurotransmitters, or antigens, can bind to, triggering specific cellular responses. Receptors are essential for the recognition and response to external stimuli in various physiological processes.
