Analgesic antidepressants promote the responsiveness of locus coeruleus neurons to noxious stimulation: implications for neuropathic pain.
Antidepressants that block the reuptake of noradrenaline and/or serotonin are among the first-line treatments for neuropathic pain, although the mechanisms underlying this analgesia remain unclear. The noradrenergic locus coeruleus is an essential element of both the ascending and descending pain modulator systems regulated by these antidepressants. Hence, we investigated the effect of analgesi...
متن کاملPossible involvement of activated locus coeruleus-noradrenergic neurons in pain-related sleep disorders.
The locus coeruleus (LC) is a noradrenergic brainstem structure that is considered to play a role in promoting arousal. To further clarify the role of LC noradrenergic neurons, we performed an optogenetic assay by injecting AAV-channelrhodopsin-2 (ChR2) into the LC of cre-tyrosine hydrolase (TH) mice. We found here that the specific activation of LC noradrenergic neurons produced a significant ...
متن کاملNoradrenergic neurons in the locus coeruleus of birds express TrkA, transport NGF, and respond to NGF.
The chicken locus coeruleus contains a population of noradrenergic neurons which express the neurotrophin receptor p75 (von Bartheld and Bothwell, 1992). To determine which neurotrophin may regulate the development of noradrenergic neurons in the chicken locus coeruleus, expression of trk receptors, retrograde transport of neurotrophins, and responses to NGF were examined. P75-expressing noradr...
متن کاملNoradrenergic neurons of the locus coeruleus are phase locked to cortical up-down states during sleep.
Nonrapid eye movement (NREM) sleep is characterized by periodic changes in cortical excitability that are reflected in the electroencephalography (EEG) as high-amplitude slow oscillations, indicative of cortical Up/Down states. These slow oscillations are thought to be involved in NREM sleep-dependent memory consolidation. Although the locus coeruleus (LC) noradrenergic system is known to play ...
متن کاملNotch-Rbpj signaling is required for the development of noradrenergic neurons in the mouse locus coeruleus.
The locus coeruleus (LC) is the main source of noradrenaline in the brain and is implicated in a broad spectrum of physiological and behavioral processes. However, genetic pathways controlling the development of noradrenergic neurons in the mammalian brain are largely unknown. We report here that Rbpj, a key nuclear effector in the Notch signaling pathway, plays an essential role in LC neuron d...
