Insights

Natural Killer (NK) cells are crucial for fighting tumors but cancer cells evade them. This chapter explores NK cell biology, challenges in malignancies, and their prognostic value in cancer.

Area of Science:

  • Immunology
  • Oncology

Background:

  • Natural Killer (NK) cells are lymphocytes that mount an antitumor response.
  • Tumor cells employ mechanisms to evade NK cell-mediated killing.
  • NK cell subsets exhibit diverse properties and functions.

Purpose of the Study:

  • To understand NK cell competence and challenges in malignancies.
  • To review the role of NK cells in tumor progression.
  • To determine the prognostic value of NK cells in distinct cancers.

Main Methods:

  • Review of NK cell biology.
  • Analysis of NK cell phenotype and effector functions in cancer patients.
  • Synthesis of findings on prognostic value.

Main Results:

  • NK cells possess antitumor capabilities but face evasion strategies.
  • NK cell functions and phenotypes vary in tumor tissues and patient blood.
  • Evidence suggests a prognostic role for NK cells in various cancers.

Conclusions:

  • NK cells are vital in cancer immunity, despite tumor evasion tactics.
  • Understanding NK cell behavior in malignancies is key for therapeutic strategies.
  • NK cell presence and function correlate with patient prognosis in distinct cancers.

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...

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...

Tumor Progression

Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

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.
