Thus, the characterization of RTKs and GPCRs led to the formulation of the concept of "signal transduction", a word first used in 1972. [61] Some early articles used the terms signal transmission and sensory transduction. [62] [63] In 2007, a total of 48,377 scientific papers—including 11,211 review papers—were published on the subject. The ...
Olfactory transduction; Sugar signal transduction; Transduction (biophysics), the conveyance of energy from a donor electron to a receptor electron, during which the class of energy changes; Transduction (genetics), the transfer of DNA from one cell to another using a virus or viral vector Tbx18 transduction, a cardiac therapy method
In physiology, transduction is the translation of arriving stimulus into an action potential by a sensory receptor. It begins when stimulus changes the membrane potential of a sensory receptor . A sensory receptor converts the energy in a stimulus into an electrical signal. [ 1 ]
Lateral transduction is the process by which very long fragments of bacterial DNA are transferred to another bacterium. So far, this form of transduction has been only described in Staphylococcus aureus, but it can transfer more genes and at higher frequencies than generalized and specialized transduction. In lateral transduction, the prophage ...
In animal cells, transfection is the preferred term, as the term "transformation" is also used to refer to a cell's progression to a cancerous state (carcinogenesis). Transduction is often used to describe virus-mediated gene transfer into prokaryotic cells. [2] [3] The word transfection is a portmanteau of the prefix trans-and the word ...
Hair cells in the cochlea are stimulated when the basilar membrane is driven up and down by differences in the fluid pressure between the scala vestibuli and scala tympani. This motion is accompanied by a shearing motion between the tectorial membrane and the reticular lamina of the organ of Corti, causing the hair bundles that link the two to ...
Cells that produce paracrine factors secrete them into the immediate extracellular environment. Factors then travel to nearby cells in which the gradient of factor received determines the outcome. However, the exact distance that paracrine factors can travel is not certain. Overview of signal transduction pathways.
Two main signal transduction mechanisms have been identified, via nuclear receptors, or via transmembrane receptors. In the first one, first messenger cross through the cell membrane, binding and activating intracellular receptors localized at nucleus or cytosol, which then act as transcriptional factors regulating directly gene expression ...
