Summary
Natural Killer (NK) cells use the NKG2D receptor to identify and eliminate transformed or infected cells. This review explores NKG2D
Area of Science:
- Immunology
- Cellular Biology
Background:
- Natural Killer (NK) cells are crucial innate immune effectors.
- NK cell function relies on a balance of activating and inhibitory receptors.
- NKG2D is a key activating receptor expressed by NK cells.
Purpose of the Study:
- To review the NKG2D receptor's role in innate immunity.
- To discuss the clinical significance of NKG2D and its ligands.
- To explore NKG2D gene polymorphisms and therapeutic potential.
Main Methods:
- Literature review of studies on NKG2D and NK cell function.
- Analysis of NKG2D ligand expression in various diseases.
- Examination of genetic variations in NKG2D.
Main Results:
- NKG2D binds to ligands overexpressed on stressed, infected, or transformed cells.
- NKG2D plays a significant role in autoimmune diseases, infections, and transplantation.
- NKG2D gene polymorphisms are associated with clinical outcomes.
Conclusions:
- The NKG2D receptor is a critical mediator of NK cell-mediated cytotoxicity.
- Understanding NKG2D mechanisms and polymorphisms offers potential for clinical applications.
- Targeting NKG2D may represent a therapeutic strategy in various diseases.

Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...

01:28Cells of the Innate Immune Response
7.1K
The innate immune response is an immediate and non-specific response against pathogens, acting swiftly to prevent the spread of infections. The primary cells involved in this response are phagocytes and natural killer (NK) cells.
Phagocytes
Phagocytes police the peripheral tissues by removing cellular debris and responding to the invasion of foreign substances or pathogens. Many phagocytes attack and remove microorganisms even before lymphocytes detect them. The human body has two general...

6.5K
Immune surveillance is an integral part of the innate immune system, involving the continuous monitoring of peripheral tissues to detect and respond to pathogens, infected cells, or cancerous cells. This surveillance is conducted primarily by natural killer (NK) cells and phagocytes, which employ distinct but complementary mechanisms to identify and eliminate threats.

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.
