|October 21, 2016
Summary
Tumor cells suppress immune responses using regulatory T cells (TREG). This review explores nonclassical, tumor-promoting roles of intratumoral TREG cells, offering new cancer treatment strategies.
Area of Science:
- Immunology
- Cancer Biology
- Oncology
Background:
- Tumorigenesis requires immune suppression mechanisms.
- Regulatory T cells (TREG) are key in dampening anti-tumor immunity.
- Recent advances reveal TREG cell heterogeneity and tissue-resident functions.
Purpose of the Study:
- To review the nonclassical functions of TREG cells in cancer.
- To explore the implications of these functions for cancer biology.
- To discuss potential therapeutic strategies targeting TREG cells in cancer treatment.
Main Methods:
- Literature review of TREG cell research in cancer.
- Analysis of studies on TREG cell heterogeneity.
- Synthesis of findings on tissue-resident TREG cell functions.
Main Results:
- TREG cells exhibit diverse, nonclassical functions beyond immune suppression.
- Intratumoral TREG cells can promote tumor growth and progression.
- Understanding TREG cell plasticity is crucial for effective cancer therapy.
Conclusions:
- TREG cells play multifaceted roles in cancer, including tumor promotion.
- Targeting nonclassical TREG cell functions offers novel therapeutic avenues.
- Further research into TREG cell biology is essential for advancing cancer treatment.

01:27Tumor Immunotherapy
2.1K
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.

6.3K
Early diagnosis and treatment can often cure cancer. However, even with treatment, residual cells called cancer stem cells (CSC) might remain, often causing tumor recurrence. These cancer stem cells possess the potential for self-renewal and multi-lineage differentiation and are often responsible for the therapeutic resistance displayed in most cancers.

7.8K
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...

Cancer treatment vaccines are a rapidly evolving field that offers a promising approach to immunotherapy. Unlike traditional vaccines that prevent diseases, cancer treatment vaccines are designed to treat existing cancers by stimulating the immune system to recognize and attack cancer cells.
Cancer vaccines come in two categories: preventive (prophylactic) and treatment (active). Preventive vaccines, such as the Human Papillomavirus (HPV) vaccine, protect against viruses that cause certain...

The targeted cancer therapies, also known as “molecular targeted therapies,” take advantage of the molecular and genetic differences between the cancer cells and the normal cells. It needs a thorough understanding of the cancer cells to develop drugs that can target specific molecular aspects that drive the growth, progression, and spread of cancer cells without affecting the growth and survival of other normal cells in the body.
