Journal ArticleDOI
Analysis of anandamide- and lysophosphatidylinositol-induced inhibition of the vasopressor responses produced by sympathetic stimulation or noradrenaline in pithed rats.
Bruno A. Marichal-Cancino,Guadalupe Manrique-Maldonado,Alain H. Altamirano-Espinoza,Inna Ruiz-Salinas,Abimael González-Hernández,Antoinette MaassenVanDenBrink,Carlos M. Villalón +6 more
TL;DR: The sympatho-inhibition by anandamide is primarily mediated by cannabinoid CB1 and, minimally, by cannabidiol-sensitive receptors, while LPI-induced inhibition of both vasopressor responses seems to be mainly mediated by postjunctional cannabidsensitive GPR55 receptors.
Journal ArticleDOI
Olcegepant blocks neurogenic and non-neurogenic CGRPergic vasodepressor responses and facilitates noradrenergic vasopressor responses in pithed rats
Victor H. Avilés-Rosas,Eduardo Rivera-Mancilla,Bruno A. Marichal-Cancino,Guadalupe Manrique-Maldonado,Alain H. Altamirano-Espinoza,A. Maassen van den Brink,Carlos M. Villalón +6 more
TL;DR: This randomized study investigated in pithed rats the effect of acute i.v. treatment with olcegepant on the neurogenic and non‐neurogenic responses of CGRPergic vasodepressor responses; and the noradrenergic vasopressor responses.
Journal ArticleDOI
The role of dopamine D2, but not D3 or D4, receptor subtypes, in quinpirole-induced inhibition of the cardioaccelerator sympathetic outflow in pithed rats.
Alain H. Altamirano-Espinoza,Abimael González-Hernández,Guadalupe Manrique-Maldonado,Bruno A. Marichal-Cancino,Inna Ruiz-Salinas,Carlos M. Villalón +5 more
TL;DR: The present study was designed to identify pharmacologically the specific D2‐like receptor subtypes involved in this sympathoinhibition by quinpirole.
Journal ArticleDOI
Intrathecal dihydroergotamine inhibits capsaicin-induced vasodilatation in the canine external carotid circulation via GR127935- and rauwolscine-sensitive receptors.
Bruno A. Marichal-Cancino,Abimael González-Hernández,Guadalupe Manrique-Maldonado,Inna Ruiz-Salinas,Alain H. Altamirano-Espinoza,Antoinette MaassenVanDenBrink,Carlos M. Villalón +6 more
TL;DR: Intrathecal dihydroergotamine seems to inhibit the external carotid vasodilatation to capsaicin by spinal activation of serotonin 5-HT(1B/1D) (probably 5- HT( 1B)) receptors and α(2) ( probably α( 2A/2C))-adrenoceptors.
Journal ArticleDOI
Role of pre-junctional CB1, but not CB2 , TRPV1 or GPR55 receptors in anandamide-induced inhibition of the vasodepressor sensory CGRPergic outflow in pithed rats.
Bruno A. Marichal-Cancino,Alain H. Altamirano-Espinoza,Guadalupe Manrique-Maldonado,Antoinette MaassenVanDenBrink,Carlos M. Villalón +4 more
TL;DR: The results suggest that anandamide‐induced inhibition of the vasodepressor sensory CGRPergic outflow is mainly mediated by pre‐junctional activation of CB1 receptors, with no pharmacological evidence for the role of CB2, TRPV1 or GPR55 receptors.
