Increased Susceptibility to Cortical Spreading Depression in the Mouse Model of Familial Hemiplegic Migraine Type 2
Familial hemiplegic migraine type 2 (FHM2) is an autosomal dominant form of migraine with aura that is caused by mutations of the α2-subunit of the Na,K-ATPase, an isoform almost exclusively expressed in astrocytes in the adult brain. We generated the first FHM2 knock-in mouse model carrying the human W887R mutation in the Atp1a2 orthologous gene. Homozygous Atp1a2(R887/R887) mutants died just ...
متن کاملP141: The Role of Microglia in Cortical Spreading Depression in Migraine
Migraine is a disorder that afflicts nearly one tenth of the population. Involving both nervous and vascular system, it has been found as a prominent factor of disability. The migraine attacks may be initiated in the brainstem or may begin peripherally in the meninges while the role of cortical activation preceding an attack is also debated. Although available treatments, more studies on migrai...
متن کاملInterplay between Cortical Spreading Depolarization and Seizures.
Cortical spreading depolarization (CSD) is an electrophysiologic phenomenon found mostly in the setting of neurologic injury resulting in the disturbance of ion homeostasis and leading to changes in the local vascular response. The bioelectric etiology of CSD shares similarities to those in epileptic disorders, yet the relationship between seizures and CSD is unclear, with several studies obser...
متن کاملA Cacna1a Knockin Migraine Mouse Model with Increased Susceptibility to Cortical Spreading Depression
Migraine is a common, disabling, multifactorial, episodic neurovascular disorder of unknown etiology. Familial hemiplegic migraine type 1 (FHM-1) is a Mendelian subtype of migraine with aura that is caused by missense mutations in the CACNA1A gene that encodes the alpha(1) subunit of neuronal Ca(v)2.1 Ca(2+) channels. We generated a knockin mouse model carrying the human pure FHM-1 R192Q mutati...
متن کاملCortical spreading depression in migraine-time to reconsider?
New evidence concerning the pathophysiology of migraine has come from the results of therapeutic transcranial magnetic stimulation (tTMS). The instantaneous responses to single pulses applied during the aura or headache phase, together with a number of other observations, make it unlikely that cortical spreading depression is involved in migraine. tTMS is considered to act by abolishing abnorma...
