Immune receptor

Index Immune receptor

An immune receptor (or immunologic receptor) is a receptor, usually on a cell membrane, which binds to a substance (for example, a cytokine) and causes a response in the immune system. [1]

In immunology, an antigen is a molecule capable of inducing an immune response (to produce an antibody) in the host organism.

B-cell receptor

The B-cell receptor or BCR is composed of immunoglobulin molecules that form a type 1 transmembrane receptor protein usually located on the outer surface of a lymphocyte type known as B cells.

Cell membrane

The cell membrane (also known as the plasma membrane or cytoplasmic membrane, and historically referred to as the plasmalemma) is a biological membrane that separates the interior of all cells from the outside environment (the extracellular space).

Complement receptor

A complement receptor is a receptor of the complement system, part of the innate immune system.

Complement system

The complement system is a part of the immune system that enhances (complements) the ability of antibodies and phagocytic cells to clear microbes and damaged cells from an organism, promotes inflammation, and attacks the pathogen's cell membrane.

An epitope, also known as antigenic determinant, is the part of an antigen that is recognized by the immune system, specifically by antibodies, B cells, or T cells.

Fc receptor

An Fc receptor is a protein found on the surface of certain cells – including, among others, B lymphocytes, follicular dendritic cells, natural killer cells, macrophages, neutrophils, eosinophils, basophils, human platelets, and mast cells – that contribute to the protective functions of the immune system.

Immune system

The immune system is a host defense system comprising many biological structures and processes within an organism that protects against disease.

Inflammation (from inflammatio) is part of the complex biological response of body tissues to harmful stimuli, such as pathogens, damaged cells, or irritants, and is a protective response involving immune cells, blood vessels, and molecular mediators.

Killer activation receptor

Killer Activation Receptors (KARs) are receptors expressed on the plasmatic membrane of Natural Killer cells (NK cells).

Killer-cell immunoglobulin-like receptor

Killer-cell immunoglobulin-like receptors (KIRs), are a family of type I transmembrane glycoproteins expressed on the plasma membrane of natural killer (NK) cells and a minority of T cells.

Major histocompatibility complex

The major histocompatibility complex (MHC) is a set of cell surface proteins essential for the acquired immune system to recognize foreign molecules in vertebrates, which in turn determines histocompatibility.

Natural killer cell

Natural killer cells or NK cells are a type of cytotoxic lymphocyte critical to the innate immune system.

NOD-like receptor

The nucleotide-binding oligomerization domain-like receptors, in short NOD-like receptors (NLRs), are intracellular sensors of PAMPs that enter the cell via phagocytosis or pores and DAMPs that are associated with cell stress.

Pathogen-associated molecular pattern

Pathogen-associated molecular patterns, or PAMPs, are molecules associated with groups of pathogens, that are recognized by cells of the innate immune system.

Pattern recognition receptor

Pattern recognition receptors (PRRs) play a crucial role in the proper function of the innate immune system.

Receptor (biochemistry)

In biochemistry and pharmacology, a receptor is a protein molecule that receives chemical signals from outside a cell.

T-cell receptor

The T-cell receptor, or TCR, is a molecule found on the surface of T cells, or T lymphocytes, that is responsible for recognizing fragments of antigen as peptides bound to major histocompatibility complex (MHC) molecules.
