Summary
Tissue-resident memory T (TRM) cells are vital for immunity and cancer defense. This review explores their diverse roles and heterogeneity across tissues, highlighting TGF-β
Area of Science:
- Immunology
- Cell Biology
Background:
- CD8+ tissue-resident memory T (TRM) cells are crucial for host defense against pathogens and cancer, and are implicated in autoimmune diseases like psoriasis.
- These cells reside in all nonlymphoid organs in mice and humans, sharing characteristics such as suppressed tissue egress and lymph node homing.
- Significant heterogeneity exists among TRM cells in different tissues, influenced by tissue-specific molecules like chemokines, cytokines, and transcription factors.
Purpose of the Study:
- To review the common and unique features of TRM cells across various tissues.
- To discuss the role of transforming growth factor (TGF)-β in generating TRM heterogeneity.
- To explore strategies for leveraging TRM cells for site-specific protection against infectious and malignant diseases.
Main Methods:
- Literature review of studies on CD8+ TRM cell heterogeneity.
- Analysis of molecular mechanisms, including the role of TGF-β.
- Synthesis of findings to propose therapeutic strategies.
Main Results:
- TRM cells exhibit both shared characteristics and tissue-specific variations in phenotype and function.
- Transforming growth factor (TGF)-β is a key mediator of TRM heterogeneity.
- Understanding tissue-specific TRM biology is essential for targeted immunotherapies.
Conclusions:
- TRM cell heterogeneity is a critical factor in their diverse roles in immunity and disease.
- Targeting TGF-β and other tissue-specific factors may enable the development of effective TRM-based therapies.
- Harnessing TRM cells offers promising avenues for site-specific protection against infections and cancers.

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.

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.

6.2K
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...

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...
