Signaling3
- Dopamine signaling contributes to key neural functions including learning and memory, movement, neuroendocrine signaling, and reward-related behaviors [ 16 ]. (nature.com)
- Phagocytosis currently is described as an endocytic process that endogenous foreign particles or pathogens larger than 0.5 μm were first recognized by phagocyte surface receptor and then uptaken and engulfed into a plasma-membrane device, known as phagosome, following initiation of a signaling cascade to generate phagolysosome by fusion of phagosome with lysosomes.

- Thus, limiting PP2Adependent dephosphorylation of GABA B Rs may be a useful strategy to increase receptor signaling for treating diseases. (mssm.edu)
Release5
- With the exception of the blood vessels, dopamine in each of these peripheral systems is synthesized locally and exerts its effects near the cells that release it. (wikipedia.org)
- In this area, dopamine acts directly to inhibit the release of prolactin. (psychiatrictimes.com)
- In the cytosol, other transporters sequester the dopamine into vesicles for storage and later release. (cloudfront.net)
- In addition, the transporter may contribute to dopamine release when the neuron depolarizes. (cloudfront.net)
- This nootropic actually reduces the release of dopamine in the prefrontal cortex. (nootropicexperience.com)
Amines1
- Like most amines, dopamine is an organic base. (wikipedia.org)
Vertebrate retina1
- The first intracellular, light-evoked responses recorded in the vertebrate retina were slow, negative going changes in membrane potential that lasted for as long as the light stimulus was present (Fig. 1). (org.es)
