T Cell Types and Functions

T Cell Types and Functions

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.
Th1 cells stimulate dendritic cells to express necessary co-stimulatory molecules on their surfaces for...

Tumor Immunotherapy

Tumor Immunotherapy

Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

Cytotoxic T Cells-mediated Immune Response

Cytotoxic T Cells-mediated Immune Response

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...

The Tumor Microenvironment

The Tumor Microenvironment

Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

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...

Background:

Thymocyte selection-associated high mobility group box protein (TOX) plays a role in T lymphocyte development.
Recent advancements, including single-cell sequencing, have highlighted the heterogeneity of T lymphocytes and TOX expression.
Exploring this heterogeneity is crucial for understanding T cell biology.

Purpose of the Study:

To investigate the heterogeneity of TOX expression in T lymphocytes.
To elucidate the functional implications of TOX heterogeneity in T cell activation and exhaustion.
To explore the potential of TOX as a therapeutic target and prognostic marker.

Main Methods:

Functional assays to assess T cell activation and exhaustion

Main Results:

TOX exhibits differential expression patterns throughout T lymphocyte development, indicating significant heterogeneity.
TOX regulation is implicated in both T cell exhaustion and activation.
Heterogeneity in TOX expression correlates with distinct T cell functional states.

Conclusions:

TOX heterogeneity is a key feature of T lymphocyte development and function.
Targeting TOX presents potential therapeutic strategies for autoimmune diseases, chronic infections, and tumors.
TOX serves as a critical factor for predicting patient response to therapies and overall survival in cancer.
