Neurotransmitter Corelease: Mechanism and Physiological Role

Open access
Hnasko, Thomas S., Edwards, Robert H.·2012·Annual Review of Physiology

Abstract

Neurotransmitter identity is a defining feature of all neurons because it constrains the type of information they convey, but many neurons release multiple transmitters. Although the physiological role for corelease has remained poorly understood, the vesicular uptake of one transmitter can regulate filling with the other by influencing expression of the H + electrochemical driving force. In addition, the sorting of vesicular neurotransmitter transporters and other synaptic vesicle proteins into different vesicle pools suggests the potential for distinct modes of release. Corelease thus serves multiple roles in synaptic transmission.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Many neurotransmitter co-release patterns had been documented previously.

    “Although many of these neurotransmitter co-release patterns had been documented previously55–57”
  • The resulting pH gradient and vesicle membrane potential can power neurotransmitter uptake by vesicular transporters.

    “This creates a pH gradient (DpH) and a vesicular membrane potential (DJ), both of which can power the uptake of neurotransmitters by vesicular transporters (Table 1).16”
  • In multitransmitter neurons, differential sensitivity of vesicular transporters to intravesicular pH or membrane potential is important for co-packaging.

    “In multitransmitter neurons, where vesicular packaging of more than one neurotransmitter occurs, it is important to consider how vesicular transporters are differentially sensitive to intravesicular factors such as pH or membrane potential.16”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
