Abstract The endocannabinoid system's significance in maintaining blood–brain barrier (BBB) integrity under physiological and pathological conditions is suggested by several reports, but the underlying molecular mechanisms are not well understood. In this paper, we investigated effects of depletion 2‐arachidonoylglycerol (2‐AG), one main endocannabinoids central nervous system, on BBB using pharmacological tools. Female Sprague–Dawley rats were injected with diacylglycerol lipase α (DAGLα)...
RNA sequencing studies on human dorsal root ganglion (hDRG) from patients suffering neuropathic pain show upregulation of OSM, linking this IL-6 family cytokine to disorders. In mice, however, OSM signaling causes itch behaviors through a direct effect its cognate receptor expressed uniquely by pruriceptive sensory neurons. We hypothesized that an expansion in function OSM-OSM (OSMR) disorders humans could be explained species differences expression and signaling. Our situ hybridization...
Abstract Pharmacological tools for chronic visceral pain management are still limited and inadequate. A 3 adenosine receptor (A AR) agonists effective in different models of persistent pain. Recently, their activity has been related to the block N-type voltage-gated Ca 2+ channels (Ca v 2.2) dorsal root ganglia (DRG) neurons. The present work aimed evaluate efficacy AR reducing postinflammatory hypersensitivity both male female rats. Colitis was induced by intracolonic instillation...
Introduction The high prevalence and severe symptoms of migraines in humans emphasizes the need to identify underlying mechanisms that can be targeted for therapeutic benefit. Clinical Endocannabinoid Deficiency (CED) posits reduced endocannabinoid tone may contribute migraine development other neuropathic pain conditions. While strategies increase levels n-arachidonoylethanolamide have been tested, few studies investigated targeting more abundant endocannabinoid, 2-arachidonoylgycerol, as...
Disruption of blood-brain barrier integrity and dramatic failure brain ion homeostasis including fluctuations pH occurs during cortical spreading depression (CSD) events associated with several neurological disorders, migraine aura, traumatic injury stroke. NHE1 is the primary regulator in central nervous system. The goal current study was to investigate role sodium-hydrogen exchanger type 1 (NHE1) blood (BBB) CSD contributions this antiporter on xenobiotic uptake. Using immortalized cell...
Abstract CRISPR-Cas9 editing is now the leading method for genome and being advanced treatment of human disease. CRIPSR could have many applications neurological diseases, including pain but traditional viral vector delivery approaches neurotoxicity limiting their use. Overcoming these issues open door treatments diseases like intractable where dorsal root ganglia (DRG) would be desired target. To this end, we describe a simple viral-vector-independent transfection primary DRG (hDRG) neurons...
Pathologies of the blood brain barrier (BBB) have been linked to a multitude CNS disorders whose pathology is poorly understood. Cortical spreading depression (CSD) has long postulated be involved in underlying mechanisms these disease states, yet full understanding remains elusive. This study utilized an vitro model BBB with b.End3 murine endothelial cells investigate role CSD by characterizing effects release major pronociceptive substances on functional integrity using TEER screening,...
Cortical spreading depression (CSD) is a pathophysiological mechanism underlying headache disorders, including migraine. Blood-brain barrier (BBB) permeability increased during CSD. Recent papers have suggested that heat shock proteins (HSP) contribute to the integrity of blood-brain barrier. In this study, possible role HSP90 in CSD-associated leak at endothelial cell was investigated using an vitro model, for blood-endothelial (BEB), and vivo model with intact BBB. We measured trans...

Background: Mounting evidence supports the role of endocannabinoid system in neurophysiology, includ-ing blood-brain barrier (BBB) function. Recent work has demonstrated that activation re-ceptors can mitigate insults to BBB during neurological disorders, like traumatic brain injury, cortical spreading depression and stroke. As alterations are associated with worsening clinical outcomes these conditions, studies herein sought examine impact depletion on integrity. Methods: Barrier integrity...
