Immunometabolism
|March 15, 2021
Summary
Cellular metabolism fuels cell growth and survival. This viewpoint explores the known immunometabolism of invariant natural killer T (iNKT) cells and compares it to CD4 T cells.
Area of Science:
- Immunology
- Cellular Metabolism
- T cell biology
Background:
- Cellular metabolism is vital for cell growth, energy production, and macromolecule synthesis.
- T cell differentiation, proliferation, and function are increasingly recognized as being modulated by metabolic processes.
- Knowledge regarding the metabolic regulation of invariant natural killer T (iNKT) cells remains limited.
Purpose of the Study:
- To review current understanding of immunometabolism in iNKT cells.
- To compare iNKT cell metabolism with that of CD4 T cells.
Main Methods:
- Literature review and synthesis of existing research on iNKT cell metabolism.
- Comparative analysis of metabolic pathways and regulation in iNKT and CD4 T cells.
Main Results:
- Emerging evidence suggests distinct metabolic requirements for iNKT cell function.
- Comparison with CD4 T cells highlights both shared and unique metabolic characteristics.
- Metabolic pathways significantly influence iNKT cell activation, differentiation, and effector functions.
Conclusions:
- Understanding iNKT cell immunometabolism is crucial for their role in immunity.
- Metabolic regulation offers potential therapeutic targets for modulating iNKT cell responses.
- Further research is needed to fully elucidate the metabolic landscape of iNKT cells.

5.9K
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
7.8K
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...

T cells are integral to our adaptive immune system, recognizing and effectively responding to foreign antigens. T cell activation and clonal selection are pivotal in orchestrating this immune response. This article elucidates these mechanisms, detailing the roles of cluster of differentiation (CD) markers, major histocompatibility complex (MHC) molecules, costimulatory signals, and the process of clonal selection.

7.1K
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.

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...
