IMMUNOLOGIC RECEPTORS Meaning and
Definition
-
Immunologic receptors, also known as immune receptors, are proteins that are integral to the functioning of the immune system. They are found on various immune cells, such as B cells, T cells, and natural killer (NK) cells, as well as on other cell types involved in immune responses.
These receptors play a crucial role in recognizing and binding to specific molecules, called antigens, that are present on foreign substances, pathogens, or even on our own cells during certain pathological conditions. By binding to these antigens, immunologic receptors initiate a cascade of signaling events that activate and coordinate immune responses.
There are several types of immunologic receptors, each with unique structures and functions. One common type is the antigen receptor, found on B cells and T cells, which enables these cells to recognize and respond to specific antigens. Another type is the Fc receptor, present on various immune cells, which binds to the constant region (Fc portion) of antibodies, allowing for their recognition and engagement in immune responses.
Immunologic receptors are essential for the discrimination between self and non-self, as well as for recognizing and eliminating harmful substances or organisms. Dysfunction or abnormalities in these receptors can result in immune disorders, such as autoimmune diseases or immunodeficiencies.
In summary, immunologic receptors are proteins expressed on immune cells that enable the immune system to recognize, bind, and respond to specific antigens. They play a pivotal role in immune responses and help maintain the balance and effectiveness of the immune system.

Etymology of IMMUNOLOGIC RECEPTORS
The word "immunologic" is derived from "immune", which comes from the Latin word "immunis" meaning exempt or free from something, particularly a duty or obligation. "Logic" refers to the study or reasoning, so "immunologic" pertains to the study of the immune system.
The word "receptor" has its roots in the Latin word "receptus", meaning to receive or accept. In biology, it refers to a specialized protein molecule that can bind to a specific substance, such as a hormone or a cell surface molecule, and initiate a cellular response.
Therefore, "immunologic receptors" refers to the protein molecules present on immune cells that are capable of recognizing and binding to specific molecules involved in immune responses, such as antigens or other immune cells, initiating a series of signaling events to trigger an immune response.
