Endocrine Signaling01:45

Endocrine Signaling

68.2K
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

41.2K
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 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...

Synaptic Signaling01:12

Synaptic Signaling

79.8K
Neurons communicate at synapses, or junctions, to excite or inhibit the activity of other neurons or target cells, such as muscles. Synapses may be chemical or electrical.

Area of Science:

  • Molecular Biology
  • Immunology
  • Cellular Biology

Background:

  • Nuclear factor E2-related factor 2 (Nrf2) is a key regulator of cellular antioxidant defenses and inflammation.
  • Macrophages are central to inflammatory responses.
  • Oxidative stress and inflammation are closely linked processes.

Purpose of the Study:

  • To investigate the molecular mechanisms by which Nrf2 suppresses inflammation.
  • To determine if Nrf2's anti-inflammatory activity is solely dependent on its antioxidant functions.

Main Methods:

  • Analysis of Nrf2's role in regulating pro-inflammatory cytokine transcription.
  • Investigation of Nrf2's impact on cellular antioxidants and redox status.

Main Results:

  • Nrf2 was found to suppress the transcriptional upregulation of pro-inflammatory cytokines.
  • This suppression occurred independently of Nrf2's known role in regulating cellular antioxidants and redox status.

Conclusions:

  • Nrf2 acts as a direct suppressor of pro-inflammatory cytokine transcription.
  • This study elucidates a novel molecular basis for Nrf2's anti-inflammatory activity, separate from its antioxidant functions.
