Summary
Natural killer T (NKT) cells play key roles in immunity and autoimmunity. This review explores NKT cell defects in human diseases and their diagnostic and therapeutic potential.
Area of Science:
- Immunology
- Cellular Biology
- Clinical Medicine
Background:
- Natural killer T (NKT) cells are regulatory lymphocytes with established roles in immunity against tumors, microbes, and autoimmunity in mouse models.
- Clinical studies suggest NKT cell deficiencies and functional defects may contribute to human diseases, but consensus is lacking.
- The precise nature of NKT cell defects and their clinical relevance in humans remain unclear.
Purpose of the Study:
- To review current approaches for analyzing NKT cell populations in patient groups.
- To propose new strategies for investigating the contribution of NKT cell defects to human diseases.
- To discuss the therapeutic prospects of utilizing NKT cells.
Main Methods:
- Review of existing clinical and laboratory studies on NKT cell analysis.
- Discussion of methodologies for patient NKT cell population assessment.
- Exploration of potential diagnostic and therapeutic strategies involving NKT cells.
Main Results:

01:27Cytotoxic T Cells-mediated Immune Response
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
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...

01:25Immune Surveillance by NK Cells and Phagocytes
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.

01:29Immune Response Against Viral Pathogens
The immune system's response to viral infections is a complex and coordinated process involving natural killer (NK) cells, T cell-mediated responses, and antibody-mediated responses.
NK Cells
NK cells are a crucial part of our innate immune system, acting as the first line of defense against viral infections. These cells can recognize and kill infected cells without prior exposure to the virus, effectively slowing down the spread of infection. Additionally, NK cells produce proinflammatory...

01:26Antigens Involved in Adaptive Immunity
An antigen is any substance the immune system identifies as foreign and potentially harmful to the body, prompting an immune response. Antigens have two functional properties: immunogenicity and reactivity. Immunogenicity is the ability of an antigen to stimulate a specific immune response. At the same time, reactivity describes the antigen's ability to react with the cells and antibodies produced in response to it.
Complete Antigens
Complete antigens possess both immunogenicity and reactivity.
