In biology, cell signaling (cell signalling in British English) is the process by which a cell interacts with itself, other cells, and the environment. Cell signaling is a fundamental property of all cellular life in prokaryotes and eukaryotes. Typically, the signaling process involves three components: the signal, the receptor, and the effector.
The modulation of gene expression in response to oscillations in cell-population density is thanks to the QS techniques regulating bacterial communication natural and artificial cultures. It is also clear that intra- and inter-species cell–cell communication occurs and is regulated by quorum sensing systems.
Signal transduction is the process by which a chemical or physical signal is transmitted through a cell as a series of molecular events.Proteins responsible for detecting stimuli are generally termed receptors, although in some cases the term sensor is used. [1]
Processes that are carried out at the cellular level, but are not necessarily restricted to a single cell. For example, cell communication occurs among more than one cell, but occurs at the cellular level.
It is not only the presence or absence of a signal that is important but also the strength. Using a chemical gradient to coordinate cell growth and differentiation continues to be important as multicellular animals and plants become more complex. This type of intercellular communication within an organism is commonly referred to as cell signalling.
The KEGG PATHWAY database is a collection of manually drawn pathway maps for metabolism, genetic information processing, environmental information processing such as signal transduction, ligand–receptor interaction and cell communication, various other cellular processes and human diseases, all based on extensive survey of published literature.
Investors should keep a close eye on stocks in a few key sectors heading into next year, analysts at UBS wrote in a note to clients. The analysts, in a Monday note, recommended investors allocate ...
Any process that mediates interactions between a cell and its surroundings. Encompasses interactions such as signaling or attachment between one cell and another cell, between a cell and an extracellular matrix, or between a cell and any other aspect of its environment.
