Activation of peripheral trigeminal fibers induces neurogenic inflammation in rat dura mater, as well as vascular and mast cell changes. These changes parallel an increase of vasodilating and permeability promoting peptides in venous effluent of the cephalic circulation. The experimental model of electrical trigeminal ganglion stimulation or systemic capsaicin administration has proven effective in detecting cellular activation in brainstem trigeminal nuclei. Animal experimental models of… 

Neurogenic inflammation in primary headaches

The evidence in support of the hypothesis that a sterile neurogenic inflammation in the meninges may be involved in generating or sustaining, via occurrence of a vicious cycle, the pain accompanying the migraine attacks is reviewed.

Dural vasodilation causes a sensitization of rat caudal trigeminal neurones in vivo that is blocked by a 5‐HT1B/1D agonist

Data show that dilation of meningeal blood vessels causes a sensitization of central trigeminal neurones and a facilitation of facial sensory processing which was blocked by activation of pre‐synaptic 5‐HT1B/1D receptors.

Depletion of calcitonin gene-related peptide from the caudal trigeminal nucleus of the rat after electrical stimulation of the Gasserian ganglion

Electrical stimulation of the Gasserian ganglion resulted in partial depletion of calcitonin gene-related peptide (CGRP) from ipsilateral central terminals of pseudounipolar primary sensory ganglions cells, which might be of importance in the pathogenesis of migraine headache.

TRPV1 in migraine pathophysiology.

Role of pituitary adenylate cyclase-activating polypeptide in nociception and migraine.

It is clear that PACAP plays an excitatory role in migraine, but its target and signalling pathways have not yet been elucidated due to the lack of non-peptide, selective agonists and antagonists.

Spontaneous Trigeminal Allodynia in Rats: A Model of Primary Headache

This model can be used as a predictive model for drug development and for studies of putative biomarkers for headache diagnosis and treatment, and to validate this as a model for migraine.

The pathophysiology of migraine: year 2005

It is possible that visual, motor or sensory aura might be responsible for the generation of the pain through the above mechanisms of cortical spreading depression underlies migraine.

The role of chemosensitive afferent nerves and TRP ion channels in the pathomechanism of headaches

Evidence that supports the critical involvement of transient receptor potential (TRP) channels in the pathophysiology of primary headaches is focused on and it is suggested that the activation level of this complex may explain some of the specific features of migraine headache.



The neurobiology of vascular head pain

The relationship of trigeminovascular fibers to the pathogenesis of vascular head pain sheds light on possible mechanisms of migraine and other central nervous system conditions associated with headache and inflammation.

The trigeminovascular system and migraine: Studies characterizing cerebrovascular and neuropeptide changes seen in humans and cats

These data characterize some aspects of the cerebrovascular physiology of the trigeminovascular system and demonstrate important interactions between this system and the effective antimigraine agents sumatriptan and dihydroergotamine and that such interactions can be represented in animal models.

Enrichment of a vasoactive neuropeptide (calcitonin gene related peptide) in the trigeminal sensory projection to the intracranial arteries

The population of trigeminal ganglion cells projecting to the cerebral vasculature is enriched in C GRP-containing neurons, and especially in the population of neurons containing CGRP and not Sub P.

Cluster Headache: Ultrastructural Evidence for Mast Cell Degranulation and Interaction with Nerve Fibres in the Human Temporal Artery

Observations of human temporal arteries from cluster headache patients and their comparison to those from a control group strongly suggest that mast cells may be this link to the pathophysiology of cluster headache.

Controlled thermocoagulation of trigeminal ganglion and rootlets for differential destruction of pain fibers: facial pain other than trigeminal neuralgia.

I describe the results of retrogasserian differential lidocaine block to aid in the selection of patients for a differential thermal lesion in the trigeminal ganglion and rootlets. This procedure

CP‐93,129, sumatriptan, dihydroergotamine block c‐fos expression within rat trigeminal nucleus caudalis caused by chemical stimulation of the meninges

It is inferred that treatment with 5‐HT1B/d agonists may be useful for the alleviation of pain in other headache conditions associated with meningeal irritation and that 5‐ HT1D receptor‐mediated blockade of neurotransmission contributes significantly to the analgesic effects of these drugs in headache.
