Abstract

Nerve growth factor (NGF), a member of the neurotrophin family, is crucial for survival of nociceptive neurons during development. Recently, it has been shown to play an important role in nociceptive function in adults. NGF is up-regulated after inflammatory injury of the skin. Administration of exogenous NGF either systemically or in the skin causes thermal hyperalgesia within minutes. Mast cells are considered important components in the action of NGF, because prior degranulation abolishes the early NGF-induced component of hyperalgesia. Substances degranulated by mast cells include serotonin, histamine, and NGF. Blockade of histamine receptors does not prevent NGF-induced hyperalgesia. The effects of blocking serotonin receptors are complex and cannot be interpretable uniquely as NGF losing its ability to induce hyperalgesia. To determine whether NGF has a direct effect on dorsal root ganglion neurons, we have begun to investigate the acute effects of NGF on capsaicin responses of small-diameter dorsal root ganglion cells in culture. NGF acutely conditions the response to capsaicin, suggesting that NGF may be important in sensitizing the response of sensory neurons to heat (a process that is thought to operate via the capsaicin receptor VR1). We also have found that ligands for the trkB receptor (brain-derived neurotrophic factor and neurotrophin-4/5) acutely sensitize nociceptive afferents and elicit hyperalgesia. Because brain-derived neurotrophic factor is up-regulated in trkA positive cells after inflammatory injury and is transported anterogradely, we consider it to be a potentially important peripheral component involved in neurotrophin-induced hyperalgesia.

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.
