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.

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...

Cancer-Critical Genes II: Tumor Suppressor Genes

Cancer-Critical Genes II: Tumor Suppressor Genes

Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...

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...

Adaptive Mechanisms in Cancer Cells

Adaptive Mechanisms in Cancer Cells

Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...

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...

Area of Science:

Epigenetics
Molecular Biology
Hematology

Background:

DNA methylation and demethylation are critical for mammalian development and cellular function, especially in the hematopoietic system.
Tet methylcytosine dioxygenase 2 (Tet2) plays a key role in catalyzing the conversion of 5-methylcytosine (5mC) to 5-hydroxymethylcytocine (5hmC).
Mutations in Tet2 are implicated in the development of various blood cancers and solid tumors.

Purpose of the Study:

To elucidate the mechanisms and biological consequences of Tet2 dysregulation in blood cancers.
To review recent findings on Tet2's involvement in lymphoid and myeloid cell development and its role in tumorigenesis.
To discuss the clinical relevance and potential therapeutic strategies targeting Tet2.

Main Methods:

Review of recent studies on Tet2 function and dysregulation in cancer.
Analysis of Tet2's role in cell development and tumorigenesis.
Exploration of Tet2 modulation by microRNAs, metabolites (e.g., vitamin C, 2-hydroxyglutarate), and other interactors.

Main Results:

Tet2 mutations are drivers of tumorigenesis in hematologic malignancies.
Tet2 dysregulation impacts lymphoid and myeloid cell development, contributing to cancer initiation and progression.
Tet2 activity is influenced by various cellular factors, including microRNAs and metabolites, highlighting complex regulatory networks.

Conclusions:

Understanding Tet2's role in blood cancers is crucial for developing targeted therapies.
Tet2 modulation by various factors presents potential therapeutic avenues.
Further research is needed to address unanswered questions regarding Tet2 in the cancer-immunity cycle.
