Insights

Notch signalling impacts cancer development, acting as both a promoter and suppressor. This review explores its role in the tumor microenvironment and anti-tumor immunity, offering insights for novel cancer therapies.

Area of Science:

  • Oncology
  • Immunology
  • Cellular Biology

Background:

  • Notch signalling is a conserved pathway crucial for development and tissue homeostasis.
  • Aberrant Notch activation is linked to cancer initiation and progression, with dual roles as promoter or suppressor.
  • The interplay between Notch signalling and the tumor immune microenvironment is an active area of research.

Purpose of the Study:

  • To review the multifaceted roles of Notch signalling in cancer.
  • To elucidate the impact of Notch signalling on anti-tumor immune responses mediated by T cells.
  • To explore therapeutic strategies targeting Notch signalling for cancer treatment, including cancer stem cell control.

Main Methods:

  • Literature review of studies on Notch signalling in cancer and immunology.
  • Analysis of Notch gene expression in T cell subsets (CD4, CD8).
  • Discussion of the tumor microenvironment and immune cell interactions.

Main Results:

  • Notch signalling exhibits context-dependent roles in tumorigenesis.
  • Notch pathway modulation in T cells influences anti-tumor immunity.
  • Specific Notch molecules and immune cells play critical roles within the tumor microenvironment.

Conclusions:

  • Notch signalling is a key regulator of the tumor immune microenvironment.
  • Understanding Notch-mediated immune responses can inform cancer therapy development.
  • Targeting Notch signalling holds potential for controlling cancer stem cells and improving treatment outcomes.

Notch Signaling Pathway03:14

Notch Signaling Pathway

The Notch signaling pathway is a major intracellular signaling pathway that is highly conserved over a broad spectrum of metazoan species. It stands unique from other intracellular signaling mechanisms in animals because notch protein itself acts as the receptor as well as the primary signaling molecule.
The Notch gene came into the limelight in 1914 after the discovery that its mutation in Drosophila melanogaster leads to a serrated (or "notched") wing margin phenotype. It was not...

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.

NK cells are large granular lymphocytes found in the blood and lymphatic system. These...

Role Of Notch Signalling In Intestinal Stem Cell Renewal01:12

Role Of Notch Signalling In Intestinal Stem Cell Renewal

Notch signaling was first discovered in Drosophila melanogaster, where it is involved in cell lineage differentiation. Notch signaling regulates the maintenance and differentiation of intestinal stem cells or ISCs by controlling the expression of atonal homolog 1 or Atoh1. Atoh1 directs cells to differentiate into secretory cells.
Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...

Principles of Disease Surveillance01:26

Principles of Disease Surveillance

Disease surveillance is the systematic collection, analysis, and interpretation of health data essential to the planning, implementation, and evaluation of public health practice. This process integrates data dissemination to entities responsible for preventing and controlling disease, injury, and disability. Surveillance systems provide crucial information for action, helping public health authorities make informed decisions to manage and prevent outbreaks, ensure public safety, optimize...

GTPases and their Regulation02:14

GTPases and their Regulation

Guanine nucleotide-binding proteins (G-proteins), also known as GTPases, are a superfamily of proteins that regulate many cellular processes, such as cell signaling, vesicular transport, and the regulation of cell shape and motility. Mutation or dysfunction of these proteins can lead to disease. There are around 40,000 known G-proteins that can broadly be classified into two groups ‒  small G-proteins consisting of a single domain and large multi-domain G-proteins.
Large G-proteins,...
