Schematic representation of an immune receptor

An immune receptor (or immunologic receptor) is a receptor, usually on a cell membrane, which binds to a ligand (usually another protein, such as cytokine) and causes a response in the immune system.

Types

The main receptors in the

T cell receptors.[1]

Comparison of different receptor targets and associated functions
Receptor Bind to [1] Function[1]
Pattern recognition receptors (PRRs)
(e.g. TLRs, NLRs
)
Pathogen-associated molecular patterns (PAMP) Mediate cytokine production → inflammation → destroying pathogen
killer inhibitor receptors
(KARs and KIRs)
Avails
NK cells
to identify abnormal host cells (KAR) or inhibit inappropriate host cell destruction (KIR)
Complement receptors
Complement proteins
on e.g. microbes
Allow phagocytic and B cells to recognize microbes and immune complexes
Fc receptors
Epitope-antibody complexes Stimulate phagocytosis
B cell receptors
Epitopes B cell differentiation into plasma cells and proliferation
T cell receptors
Linear epitopes bound to MHC Activate T cells
Cytokine receptors Cytokines Regulation and co-ordination of immune responses
