Summary
Natural killer (NK) cells are key to fighting cancer. New NK cell engagers (NKCEs) harness these cells to target tumors, offering a promising alternative to T-cell therapies for solid tumors.
Area of Science:
- Immunology
- Oncology
- Biotechnology
Background:
- T-cell based immunotherapies show limited efficacy in certain cancers.
- Targeting innate immunity, specifically NK cells, presents an alternative strategy.
- NK cells are crucial for immune responses against aberrant cells.
Purpose of the Study:
- To review recent advances in NK cell engagers (NKCEs).
- To focus on NKCEs targeting CD16A and NKp46 receptors.
- To provide an overview of ongoing clinical trials for NKCEs.
Main Methods:
- Review of scientific literature on NK cell engagers.
- Analysis of bi-, tri-, and multi-specific antibodies targeting NK cells.
- Examination of ongoing clinical trials for NKCEs.
Main Results:
- NKCEs redirect immune effector cells, including NK cells, to eradicate tumor cells.
- Antibody-dependent cellular cytotoxicity is enhanced by NKCEs in solid tumors.
- NKCEs show potential in improving immunotherapeutic effectiveness.
Conclusions:
- NKCEs represent a pioneering approach in cancer immunotherapy.
- Targeting NK cell-activating receptors like CD16A and NKp46 is a key strategy.
- Ongoing clinical trials are evaluating the safety, efficacy, and potential of NKCEs.

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
480
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.

01:22T Cell Activation and Clonal Selection
671
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.

01:28Cells of the Innate Immune Response
1.6K
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...

1.4K
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.
