NK cells regulating T cell responses: mechanisms and outcome
Trends in Immunology
|November 30, 2014
Summary
Natural killer (NK) cells regulate adaptive immunity by directly interacting with T cells or indirectly via antigen-presenting cells. Understanding these mechanisms is crucial for managing infections and diseases.
Area of Science:
- Immunology
- Infectious Disease
Background:
- Natural killer (NK) cells are key innate immune effectors.
- NK cells modulate adaptive immune responses, influencing T cell activity.
Purpose of the Study:
- To review recent findings on NK cell regulation of adaptive immunity.
- To outline emerging principles of NK cell-mediated immune regulation.
Main Methods:
- Literature review of recent immunological studies.
- Analysis of direct and indirect NK cell interaction mechanisms.
Main Results:
- NK cell regulation of T cells can be stimulatory or inhibitory.
- Regulation occurs through direct NK-T cell contact and indirect pathways involving antigen-presenting cells and pathogen load.
Conclusions:
- NK cells play a complex role in adaptive immunity.
- Mechanisms of NK cell regulation impact disease and infection outcomes.

Cytotoxic T Cells-mediated Immune Response
8.5K
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...

T Cell Activation and Clonal Selection
17.9K
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.

T Cell Types and Functions
3.6K
When T cells with CD4 markers are activated, they give rise to two types of effector cells: helper T cells and regulatory T cells. Meanwhile, T cells with CD8 markers differentiate into effector cytotoxic T cells. The differentiation of CD4 T cells into helper T cell subsets, such as Th1, Th2, and Th17 cells, is dependent on the antigen type, antigen-presenting cell, and regulatory cytokines.

Cells of the Innate Immune Response
10.9K
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...

Immune Response Against Viral Pathogens
2.7K
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...

NF-κB-dependent Signaling Pathway
10.9K
The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.
