Summary
Transforming growth factor-beta (TGF-β) is crucial for developing CD103+ CD8 tissue-resident memory T (TRM) cells. Understanding TGF-β
Area of Science:
- Immunology
- Cell Biology
- Molecular Biology
Background:
- CD8 tissue-resident memory T (TRM) cells are vital for immunity in tissues.
- CD8 TRM cells are categorized into CD103- and CD103+ subsets.
- Transforming growth factor-beta (TGF-β) is essential for CD103+ CD8 TRM cell development.
Purpose of the Study:
- To review the role of TGF-β in CD103+ CD8 TRM cell development and maintenance.
- To explore tissue-specific TGF-β activation mechanisms mediated by integrins.
- To discuss TGF-β's regulatory mechanisms in CD103+ CD8 TRM cell biology.
Main Methods:
- Literature review and synthesis of current research.
- Analysis of molecular mechanisms of TGF-β signaling.
- Investigation of integrin-mediated TGF-β activation in TRM cell development.
Main Results:
- TGF-β is critical for the development and maintenance of CD103+ CD8 TRM cells.
- Integrins mediate tissue-specific activation of TGF-β.
- TGF-β employs specific mechanisms to regulate CD103+ CD8 TRM cell populations.
Conclusions:
- TGF-β plays a pivotal role in regulating CD103+ CD8 TRM cells.
- Understanding these mechanisms can inform vaccine design.
- Targeting TGF-β pathways may enhance TRM cell-mediated immunity.

T Cell Activation and Clonal Selection
13.6K
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.

TGF - β Signaling Pathway
8.2K
The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors...

T Cell Types and Functions
1.7K
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.

Cytotoxic T Cells-mediated Immune Response
5.6K
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...
