Insights

Notch signaling enables immune cells to communicate with stromal cells in specific niches. This interaction guides immune cell development and function by conveying spatial and temporal information.

Area of Science:

  • Cellular biology
  • Immunology
  • Developmental biology

Background:

  • Cell-to-cell communication is vital for multicellular organism organization.
  • Notch signaling mediates local interactions using short-lived signals sensitive to spatial cues.
  • Immune cell development, differentiation, and function depend on Notch signaling.

Purpose of the Study:

  • To review how immune cells utilize Notch signaling with stromal cells.
  • To explore the factors controlling these immune-stromal cell interactions.
  • To understand how Notch signals provide spatial, quantitative, and temporal information to immune cells.

Main Methods:

  • Literature review focusing on Notch signaling in immune cell niches.
  • Analysis of interactions between Notch receptors and ligands in lymphohematopoietic organs.
  • Emphasis on regulatory factors and information transfer via Notch signaling.

Main Results:

  • Immune cells engage stromal cells via Notch receptors in specialized niches.
  • Notch-activating ligands on stromal cells regulate immune cell programming.
  • Spatial, quantitative, and temporal information is encoded in Notch signals.

Conclusions:

  • Notch signaling is a key mechanism for immune cell programming within specific microenvironments.
  • Understanding these interactions is crucial for deciphering immune system regulation.
  • This review highlights the role of Notch signaling in immune cell function and development.

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...

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...

Regulation of Hematopoietic Stem Cells01:01

Regulation of Hematopoietic Stem Cells

All blood and immune cells are produced from the multipotent hematopoietic stem cells (HSCs) by the process of hematopoiesis. However, they all have a limited life span. In addition, many are depleted in immune surveillance or combatting an injury or infection. This makes blood one of the most regenerative tissues. Hematopoiesis helps replenish these blood and immune cells, restoring the body's normal functioning. However, overproduction of blood and immune cells can make them cancerous or...

Stem Cell Niche01:26

Stem Cell Niche

The stem cell niche is the dynamic microenvironment where stem cells reside. Inside these niches, the cells may remain undifferentiated, undergo high self-renewal, or become lineage-specific progenitors. Stem cells coexist with other niche cells, such as stromal cells. They also interact closely with the ECM. Cell-cell and cell-matrix communication occur via adhesion molecules or soluble factors that signal the stem cells and determine their fate. Stromal cells also provide survival signals to...

Regulation of Angiogenesis and Blood Supply01:24

Regulation of Angiogenesis and Blood Supply

Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits.  Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...

Receptor Downregulation in MVBs01:15

Receptor Downregulation in MVBs

Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
The EGFR can initiate signaling pathways that  lead to cell proliferation, migration, and differentiation. Overexpression of EGFR  stimulates cells to proliferate. Excessive  EGFR...
