Insights

Natural killer (NK) cells are crucial for immunotherapy. This review focuses on the NKG2C receptor, examining its role in immune surveillance and therapeutic potential, particularly in cytomegalovirus infections.

Area of Science:

  • Immunology
  • Cell Biology
  • Cancer Research

Background:

  • Natural killer (NK) cells are increasingly recognized for their therapeutic potential in oncology and infectious diseases.
  • NK cell activity is regulated by a balance of activating and inhibitory receptors interacting with ligands on target cells.
  • The CD94/NKG2C receptor is a key activating receptor on NK cells, belonging to the C-type lectin-like family.

Purpose of the Study:

  • To summarize recent findings on the clinical significance of the NKG2C receptor.
  • To explore the contribution of NKG2C to current and future immunotherapeutic strategies.
  • To elucidate the functional and molecular characteristics of CD94/NKG2C and its interactions.

Main Methods:

  • Literature review of current research on NKG2C.
  • Analysis of functional characteristics and molecular features of the CD94/NKG2C receptor.
  • Examination of interactions between NKG2C, HLA-E, and presented antigens.

Main Results:

  • The NKG2C receptor plays a critical role in immunosurveillance, notably in human cytomegalovirus infections.
  • CD94/NKG2C interacts with the HLA-E molecule and presented antigens.
  • The review highlights the unique ligand-sharing properties of NKG2C with the inhibitory receptor NKG2A.

Conclusions:

  • The NKG2C receptor is a promising target for immunotherapies due to its role in NK cell activation.

G Protein-coupled Receptors

G Protein-Coupled Receptors or GPCRs are membrane-bound receptors that transiently associate with heterotrimeric G proteins and induce an appropriate response to sensory stimuli such as light, odors, hormones, cytokines, or neurotransmitters.
GPCRs are also called heptahelical, 7TM, or serpentine receptors, and consist of seven (H1-H7) transmembrane alpha-helices that span the bilayer to form a cylindrical core. The transmembrane helices are connected by three extracellular loops and three...

Ligand-Gated Ion Channel Receptor: Gating Mechanism01:30

Ligand-Gated Ion Channel Receptor: Gating Mechanism

Ligand-gated ion channels are transmembrane proteins that play a vital role in intercellular communication and functions of the nervous system. They allow the influx of ions across the membrane once the neurotransmitter binds, allowing the subsequent transmission of electrical excitation across the neurons. Other ligand-gated ion channels, like the γ-aminobutyric acid (GABA) receptor, permit anions like chloride into the cells on the binding of the GABA molecule. Their entry into the cell...

Non-gated Ion Channels01:24

Non-gated Ion Channels

Ion channels are specialized proteins on the plasma membrane that allow charged ions to pass down their electrochemical gradient. Their main function is to maintain the membrane potential which is critical for cell viability. These channels are either gated or non-gated and can transport more than a thousand ions within milliseconds for the cellular event to occur.
Compared to the gated ion channels, the non-gated channels, also known as leakage or passive channels, have no gating mechanism....

Transducer Mechanism: Enzyme-Linked Receptors

Enzyme-linked receptors are cell-surface receptors acting as an enzyme or associating with an enzyme intracellularly. They make excellent drug targets. Drugs can bind to the extracellular ligand-binding domain or directly affect their enzymatic domain and alter their activity.
Major types that are helpful drug targets include:

Enzyme-linked Receptors01:00

Enzyme-linked Receptors

Enzyme-linked receptors are proteins that act as both receptor and enzyme, activating multiple intracellular signals. This is a large group of receptors that include the receptor tyrosine kinase (RTK) family. Many growth factors and hormones bind to and activate the RTKs.
Neurotrophin (NT) receptors are a family of RTKs, including trkA, trkB, and trkC (tropomyosin-related kinase) receptors. TrkA is specific for nerve growth factor (NGF), neurotrophin-6, and neurotrophin-7. TrkB binds...

Ligand-gated Ion Channels01:19

Ligand-gated Ion Channels

Ligand-gated ion channels are transmembrane proteins with a channel for ions to pass through and a binding site for a ligand. The channel opens only when a ligand attaches to the binding site.
Three Subfamilies of Ligand-gated Ion Channels
Ligand-gated ion channels fall into three subfamilies. The 'Cys-loop' includes the nicotinic acetylcholine receptors, γ-aminobutyric acid (GABA), glycine, and 5-hydroxytryptamine receptors. The second one is the 'Pore-loop' channels that...
