Summary
Natural killer (NK) cells show promise in cancer immunotherapy. This review explores cellular, cytokine, and antibody-based NK cell therapies, addressing challenges to improve cancer treatment outcomes.
Area of Science:
- Immunology
- Oncology
- Biotechnology
Background:
- Natural killer (NK) cells possess inherent cancer-targeting capabilities, making them a key focus in cancer immunotherapy.
- Decades of research have explored various methods to leverage NK cells, including cytokines, small molecules, antibodies, and cell transfer.
Purpose of the Study:
- To review and categorize current NK cell-based cancer immunotherapy strategies.
- To discuss the advancements, limitations, and future directions for optimizing NK cell therapies.
Main Methods:
- Categorization of NK cell therapies into cellular, cytokine-based, and antibody-based approaches.
- Review of existing literature on NK cell therapy efficacy, safety, and challenges.
Main Results:
- NK cell therapies are broadly classified into unmodified/engineered cellular therapies, cytokine derivatives (e.g., IL-2, IL-15), and antibody-based treatments (e.g., checkpoint inhibitors, NK cell engagers).
- Despite promising safety profiles, challenges like limited in vivo persistence and tumor microenvironment suppression impact efficacy.
Conclusions:
- NK cell-based immunotherapies offer a promising avenue for cancer treatment.
- Further strategies are needed to overcome current limitations and enhance the durability and effectiveness of NK cell therapies in clinical settings.

01:27Tumor Immunotherapy
398
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.

01:27Cytotoxic T Cells-mediated Immune Response
725
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...

01:28Cells of the Innate Immune Response
1.1K
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...

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...

01:25Immune Surveillance by NK Cells and Phagocytes
918
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.

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.
