Cells of the Adaptive Immune Response

Cells of the Adaptive Immune Response

The T and B lymphocytes of the adaptive immune system develop from common lymphoid progenitor cells in the bone marrow. These progenitors give rise to precursors that eventually develop into both T and B lymphocytes. As these precursors mature, they gain the ability to detect and respond to foreign antigens in the body, a process known as immunocompetence. Additionally, these precursors acquire self-tolerance, a process that ensures they do not react to self-antigens. This intricate system...

T Cell Activation and Clonal Selection

T Cell Activation and Clonal Selection

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.
Naive T cells that have not yet encountered an antigen express two primary CD...

Area of Science:

Immunology
Cellular Biology
Metabolism

Background:

Cellular metabolism is increasingly recognized as vital for T-lymphocyte differentiation and function.
While much research has focused on murine models, human T-lymphocyte metabolism is now under investigation.

Purpose of the Study:

To investigate the role of glycolytic and mitochondrial activity in human CD4(+) and CD8(+) T-cell function.
To correlate metabolic activity with T-cell functional outcomes.

Main Methods:

Analysis of glycolytic and mitochondrial activity in activated human T cells.
Assessment of T-cell function under conditions of glucose deprivation, mitochondrial restriction, and inhibition of glycolysis.

Main Results:

Neither glucose deprivation nor mitochondrial restriction significantly impaired cytokine production in T cells.
The glycolytic inhibitor 2-deoxyglucose markedly impaired T-cell function.
Glycolytic activity is essential for optimal human T-cell function.

Conclusions:

Cellular metabolism, particularly glycolysis, plays a critical role in human T-lymphocyte function.
Targeting glycolysis may represent a therapeutic strategy for modulating T-cell responses.
