Functional interactions between glutamate receptors and TRPV1 in trigeminal sensory neurons
Background Elevated glutamate levels within injured muscle exacerbate pain conditions and modulate functional properties of muscle nociceptors via peripheral glutamate receptors. Direct injections of capsaicin in muscle tissue significantly lower mechanical thresholds, and the blockade of TRPV1 attenuates mechanical hyperalgesia resulting from eccentric muscle contraction. This study explores h...
متن کاملProlactin modulates TRPV1 in female rat trigeminal sensory neurons.
Sex dependency in pain perception is well documented and is thought to be attributable to the effect of reproductive hormones on nociceptive processing. In the present study, we evaluated whether estradiol alters gene transcription in the trigeminal ganglia (TG) of ovariectomized rats (OVX). These experiments demonstrated a dramatic (40-fold) upregulation of prolactin (PRL) expression in TG by ...
متن کاملTRPA1-mediated responses in trigeminal sensory neurons: interaction between TRPA1 and TRPV1.
The transient receptor potential (TRP)A1 channel is involved in the transduction of inflammation-induced noxious stimuli from the periphery. Previous studies have characterized the properties of TRPA1 in heterologous expression systems. However, there is little information on the properties of TRPA1-mediated currents in sensory neurons. A capsaicin-sensitive subset of rat and mouse trigeminal g...
متن کاملSumatriptan inhibits TRPV1 channels in trigeminal neurons.
OBJECTIVE To understand a possible role for transient potential receptor vanilloid 1 (TRPV1) ion channels in sumatriptan relief of pain mediated by trigeminal nociceptors. BACKGROUND TRPV1 channels are expressed in small nociceptive sensory neurons. In dorsal root ganglia, TRPV1-containing nociceptors mediate certain types of inflammatory pain. Neurogenic inflammation of cerebral dura and blo...
متن کاملTRPV1 receptors and nasal trigeminal chemesthesis.
The trigeminal nerve responds to a wide variety of irritants. Trigeminal nerve fibers express several receptors that respond to chemicals, including TRPV1 (vanilloid) receptors, acid-sensing ion channels, P2X (purinergic) receptors, and nicotinic acetylcholine receptors. In order to assess whether TRPV1 plays a role in responses to a broad array of substances, TRPV1 (along with green fluorescen...
