Summary
Natural killer (NK) cell immunotherapies show promise for treating leukemia, offering an alternative to conventional treatments. This review explores NK cell function, their impairment in leukemia, and various NK cell-based therapies under investigation.
Area of Science:
- Immunology
- Hematology
- Oncology
Background:
- Leukemia is a blood and bone marrow cancer originating from abnormal hematopoietic stem cells (HSCs).
- Conventional treatments like chemotherapy and radiation have limitations, including increased infection risk and side effects.
- Natural Killer (NK) cells are crucial immune cells for eliminating cancer cells.
Purpose of the Study:
- To review the biology of NK cells and their receptors.
- To discuss the functional impairment of NK cells in leukemia patients.
- To explore current and future NK cell-based immunotherapies for leukemia.
Main Methods:
- Review of scientific literature on NK cell biology and leukemia.
- Analysis of NK cell receptor function and its role in immune regulation.
- Compilation of data on various NK cell immunotherapeutic strategies.
Main Results:
- NK cells play a vital role in the innate immune response against cancer.
- Leukemia can lead to functional impairment of NK cells.
- Several immunotherapeutic approaches utilizing NK cells are under investigation.
Conclusions:
- NK cell-based immunotherapies represent a promising avenue for leukemia treatment.
- Further research into NK cell function and targeted therapies can improve patient outcomes.
- Monoclonal antibodies, adoptive transfer, CAR-NKs, and BiKEs/TriKEs are key areas of development.

3.7K
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...

01:27Tumor Immunotherapy
711
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.

01:28Cells of the Innate Immune Response
5.2K
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...

01:25Immune Surveillance by NK Cells and Phagocytes
4.6K
Immune surveillance is an integral part of the innate immune system, involving the continuous monitoring of peripheral tissues to detect and respond to pathogens, infected cells, or cancerous cells. This surveillance is conducted primarily by natural killer (NK) cells and phagocytes, which employ distinct but complementary mechanisms to identify and eliminate threats.

5.1K
Combining two or more treatment methods increases the life span of cancer patients while reducing damage to vital organs or tissue from the overuse of a single treatment. Combination therapy also targets different cancer-inducing pathways, thus reducing the chances of developing resistance to treatment.
The combination of the drug acetazolamide and sulforaphane is a good example of combination therapy to treat cancer. The cells in the interior of a large tumor often die due to the hypoxic and...
