Natural killer (NK) cells are crucial for innate immunity, defending against tumors and viruses. This review covers the discovery of NK cell receptors and their characteristics in health and disease.
Area of Science:
- Immunology
- Cell Biology
Background:
- Natural killer (NK) cells are vital innate immune cells.
- They exhibit cytotoxic activity against tumor and virus-infected cells.
- NK cells release cytokines, contributing to host defense.
Purpose of the Study:
- To provide a historical overview of human NK cell receptor discovery.
- To outline the phenotypic features of NK cells in healthy individuals.
- To describe NK cell alterations in pathological conditions.
Main Methods:
- Historical review of NK cell research.
- Characterization of NK cell surface receptors and markers using monoclonal antibodies.
- Analysis of NK cell phenotypes in healthy and diseased states.
Main Results:
- Discovery of NK cell receptors enabled functional characterization.
- Detailed phenotypic features of differentiating and mature NK cells are presented.
- Alterations in NK cell phenotype associated with certain pathologies are discussed.
Conclusions:
- NK cells are key players in innate immunity with diverse functions.
- Understanding NK cell receptors and phenotypes is crucial for immunology.
- NK cell analysis aids in understanding and potentially treating diseases.

Cells of the Innate Immune Response
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...

Before encountering any antigen, lymphocytes express these receptors. On B cells, the antigen receptor is a membrane-bound antibody molecule called BCR; on T cells, it is a T cell receptor or TCR. B and T cell receptors are composed of two...
