Diversity in Cell Signaling Responses01:22

Diversity in Cell Signaling Responses

8.0K
The physiological function of a cell and cellular communication are outcomes of a range of extrinsic signals, intracellular signaling pathways, and cellular responses. No two cell types express the same repertoire of signaling components. Receptors are highly selective for their cognate ligands, but once activated, they can alter multiple cellular processes such as DNA transcription, protein synthesis, and metabolic activity.

What is Cell Signaling?

131.0K
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.

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

40.9K
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...

Background:

  • Cell behavior is dictated by physical interactions with the extracellular matrix.
  • The Hippo signaling pathway, involving transcriptional regulators YAP and TAZ, plays a key role in integrating these mechanical cues.
  • Understanding YAP/TAZ function is critical for comprehending tissue homeostasis and disease pathogenesis.

Purpose of the Study:

  • To review the mechanisms by which YAP and TAZ integrate mechanical signals with other cellular pathways.
  • To elucidate the role of YAP and TAZ in controlling cell proliferation, plasticity, and stemness for tissue regeneration.
  • To discuss the implications of aberrant YAP and TAZ activation in disease, particularly cancer.

Main Methods:

  • Literature review of studies on YAP, TAZ, cell mechanics, and signaling pathways.
