Summary
Invariant Natural Killer T (NKT) cells play a key role in tumor immunity. Restoring their numbers and function shows promise for effective cancer immunotherapy strategies.
Area of Science:
- Immunology
- Oncology
Background:
- Human invariant Valpha24 Natural Killer T (NKT) cells are unique lymphocytes defined by their T-cell receptor (TCR) Valpha24-Jalpha18 and Vbeta11 chains.
- These cells are crucial in tumor immunity, responding to the glycolipid alpha-Galactosylceramide by releasing cytokines that modulate other immune cells.
Purpose of the Study:
- To review quantitative alterations and functional impairments of Valpha24 NKT cells in cancer patients.
- To summarize the progress in NKT cell-based tumor immunotherapy.
Main Methods:
- Review of existing literature on Valpha24 NKT cell numbers and functions in various cancers.
- Summary of clinical applications of NKT cell-based immunotherapy.
Main Results:
- Abnormalities in Valpha24 NKT cell numbers and functions are observed in patients with malignant diseases.
- NKT cells modulate NK cells, T cells, and dendritic cells upon activation.
Conclusions:
- Restoring adequate numbers of functional Valpha24 NKT cells is a logical therapeutic strategy for cancer treatment.
- NKT cell-based immunotherapy holds significant potential for cancer treatment.

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 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...

Targeted Cancer Therapies
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.

Cells of the Innate Immune Response
The innate immune response is an immediate and non-specific response against pathogens, acting swiftly to prevent the spread of infections. The primary cells involved in this response are phagocytes and natural killer (NK) cells.
Phagocytes
Phagocytes police the peripheral tissues by removing cellular debris and responding to the invasion of foreign substances or pathogens. Many phagocytes attack and remove microorganisms even before lymphocytes detect them. The human body has two general...

Overview
Cancer Vaccines
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...
