Fruit Development, Structure, and Function01:58

Fruit Development, Structure, and Function

25.5K
Fruits form from a mature flower ovary. As seeds develop from the ovules contained within, the ovary wall undergoes a series of complex changes to form fruit. In some fruits, such as soybeans, the ovary wall dries; in other fruits, such as grapes, it remains fleshy. In some cases, organs other than the ovary contribute to fruit formation; such fruits are called accessory fruits.

Endocrine Signaling01:45

Endocrine Signaling

68.3K
Endocrine cells produce hormones to communicate with remote target cells found in other organs. The hormone reaches these distant areas using the circulatory system. This exposes the whole organism to the hormone but only those cells expressing hormone receptors or target cells are affected. Thus, endocrine signaling induces slow responses from its target cells but these effects also last longer.

Bacterial Signaling01:30

Bacterial Signaling

41.4K
Bacterial signaling can occur within bacteria (intracellular) or between bacteria (intercellular). At times, a group of bacteria behaves like a community. To achieve this, they engage in quorum sensing, the perception of higher cell density that causes changes in gene expression. Quorum sensing involves both extracellular and intracellular signaling. The signaling cascade starts with a molecule called an autoinducer (AI). Individual bacteria produce AIs that move out of the bacterial cell...

Yeast Signaling01:28

Yeast Signaling

17.3K
Yeasts are single-celled organisms, but unlike bacteria, they are eukaryotes (cells with a nucleus). Cell signaling in yeast is similar to signaling in other eukaryotic cells. A ligand, such as a protein or a small molecule released from a yeast cell, attaches to a receptor on the cell surface. The binding stimulates second-messenger kinases to activate or inactivate transcription factors that further regulate gene expression. Many of the yeast intracellular signaling cascades have similar...

What is Cell Signaling?

131.1K
Despite the protective membrane that separates a cell from the environment, cells need the ability to detect and respond to environmental changes. Additionally, cells often need to communicate with one another. Unicellular and multicellular organisms use a variety of cell signaling mechanisms to communicate to respond to the environment.

Paracrine Signaling01:21

Paracrine Signaling

59.7K
Paracrine signaling allows cells to communicate with their immediate neighbors via secretion of signaling molecules. Such a signal can only trigger a response in nearby target cells because the signal molecules degrade quickly or are inactivated if not taken up. Prominent examples of paracrine signaling include nitric oxide signaling in blood vessels, synaptic signaling of neurons, the blood clotting system, tissue repair/wound healing, and local allergic skin reactions. Nitric oxide as a...

Summary
This summary is machine-generated.

Purinergic signaling, involving adenosine triphosphate (ATP) and its derivatives, regulates oligodendrocyte development and myelination in the central nervous system (CNS). This pathway is crucial for myelin production and may be involved in CNS injury and disease.

Area of Science:

  • Neuroscience
  • Cell Biology
  • Molecular Signaling

Background:

  • Myelin is essential for rapid nerve impulse transmission in vertebrates.
  • Oligodendrocytes produce myelin in the central nervous system (CNS), requiring progenitor cell proliferation, migration, and differentiation.
  • Neuronal signals are hypothesized to regulate oligodendrocyte development, but specific mechanisms are debated.

Purpose of the Study:

  • To review the role of purinergic signaling in oligodendrocyte development and myelination.
  • To discuss the sources of extracellular purines and their receptors in the CNS.
  • To explore the implications of purinergic signaling in CNS injury and disease.

Main Methods:

  • Literature review of studies on purinergic signaling and oligodendrocyte biology.
  • Analysis of evidence linking adenosine triphosphate (ATP) and its derivatives to oligodendrocyte lineage cells.
  • Examination of purinergic receptor expression and function in the context of myelination.

Main Results:

  • Purinergic signaling, mediated by ATP and its derivatives, is increasingly recognized as a regulator of oligodendrocyte proliferation, differentiation, and myelination.
  • Specific purinergic receptors on oligodendrocyte progenitor cells respond to extracellular purines, influencing their development.
  • Changes in purinergic receptor expression correlate with oligodendrocyte differentiation.

Conclusions:

  • Purinergic signaling is a key pathway influencing oligodendrocyte development and CNS myelination.
  • Understanding purinergic signaling offers insights into maintaining myelin integrity and potential therapeutic targets for CNS disorders.
