IMMUNOLOGICAL RECEPTORS Meaning and
Definition
-
Immunological receptors are specialized proteins found on the surface of immune cells that play a crucial role in the recognition and response to foreign substances, such as pathogens or antigens. These receptors are an essential component of the immune system, allowing immune cells to distinguish between self and non-self molecules, thereby enabling the body to mount an appropriate immune response.
There are several types of immunological receptors, including antigen receptors and pattern recognition receptors. Antigen receptors, such as the B cell receptors (BCRs) and T cell receptors (TCRs), are responsible for recognizing specific antigens, which are molecules found on the surface of pathogens or other foreign substances. The binding of an antigen to its corresponding receptor triggers a cascade of signaling events within the immune cell, leading to an immune response against the recognized entity.
Pattern recognition receptors (PRRs) are another type of immunological receptor that recognizes common molecular patterns present in a wide variety of pathogens. PRRs are involved in innate immunity, the body's first line of defense against invading pathogens, and they can detect viral, bacterial, or fungal components. PRRs bind to these pathogen-associated molecular patterns (PAMPs) and induce an inflammatory response, activating other immune cells to help eliminate the invading microorganisms.
Overall, immunological receptors are integral to immune function, as they facilitate the recognition and response to foreign substances, contributing to the body's ability to defend against pathogens and maintain homeostasis.

Etymology of IMMUNOLOGICAL RECEPTORS
The etymology of the term "Immunological Receptors" can be broken down as follows:
1. Immunological: The word "immunological" is derived from the term "immune" and the suffix "-logical". "Immune" originates from the Latin word "immunis", which means "exempt or free from". The suffix "-logical" is derived from the Greek word "logos", meaning "study" or "knowledge". Therefore, "immunological" refers to the study or knowledge of immunity or the immune system.
2. Receptors: The word "receptors" comes from the Latin word "receptus", which means "to receive or take". In biology, a receptor refers to a specialized protein molecule on the surface of a cell or inside it, which binds to specific substances such as hormones, antigens, or neurotransmitters, transmitting signals to initiate a biological response.
