Insights

Natural killer (NK) and natural killer T (NKT) cells show promise for cancer immunotherapy due to their rapid anti-tumour responses. Further research into their functions and behaviour is crucial for developing effective cell-based cancer treatments.

Area of Science:

  • Immunology
  • Cancer Biology
  • Cell Therapy

Background:

  • Natural killer (NK) cells and natural killer T (NKT) cells are lymphocytes with shared similarities.
  • Both NK and NKT cells exhibit rapid responses to tumour cells, contributing to anti-tumour immunity.
  • Their potential in cancer immunotherapy has spurred research into manipulating these cells.

Purpose of the Study:

  • To explore the potential of NK and NKT cells in innovative cancer therapies.
  • To understand how the developmental environment influences NK and NKT cell reactivity.
  • To identify key factors for the rational application of these cells in human cancer immunotherapy.

Main Methods:

  • Review of recent studies on NK and NKT cell biology.
  • Analysis of factors influencing immune cell development and function.
  • Investigation of effector functions, migration, and survival properties.

Main Results:

  • NK and NKT cells possess inherent anti-tumour capabilities.
  • The microenvironment significantly shapes the immune reactivity of NK and NKT cells.
  • Understanding their specific functions and behaviours is critical for therapeutic development.

Conclusions:

  • NK and NKT cells represent promising candidates for cancer immunotherapy.
  • Further elucidation of their effector functions, migration, and survival is necessary.
  • Optimizing the use of NK and NKT cells requires a deeper understanding of their in vivo behaviour.

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...
Cells of the Innate Immune Response01:28

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...
Targeted Cancer Therapies02:57

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.
There are several types of targeted therapies against specific...

Immune Surveillance by NK Cells and Phagocytes01:25

Immune Surveillance by NK Cells and Phagocytes

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.
