Abstract GPR37L1 is an orphan receptor that couples through heterotrimeric G-proteins to regulate physiological functions. Since its role in humans not fully defined, we used unbiased computational approach assess the clinical significance of rare genetic variants found among 51,289 whole exome sequences from DiscovEHR cohort. Briefly, coding were binned according predicted pathogenicity, and analyzed by Sequence Kernel Association testing reveal significant associations with disease diagnostic codes for epilepsy migraine, others. do prove causality, then functionally SK-N-MC cells evaluate potential signaling differences pathogenicity.

Familial hemiplegic migraine type 2 (FHM2) is linked to Na,K-ATPase α isoform mutations, including that of G301R. Mice heterozygous for this mutation ([Formula: see text]) show cerebrovascular hypercontractility associated with amplified Src kinase signaling, and exaggerated neurovascular coupling. This study hypothesized targeting Na,K-ATPase-dependent phosphorylation pNaKtide would normalize cerebral perfusion coupling in [Formula: text] mice. The effect on blood flow was assessed using laser speckle contrast imaging awake, head-fixed mice cranial windows a longitudinal design. At baseline, compared wild type, exhibited increased middle artery tone; whisker stimulation leading an increase sensory cortex flow. No difference between genotypes telemetrically pressure occurred. K ir 2.1 channel expression endothelium. Two weeks treatment normalized tone, endothelial expression, Inhibition the signaling prevented excessive vasoconstriction disturbances had only minor hypotensive similar both genotypes. These results demonstrate novel target FHM2.

Abstract Migraine is a highly prevalent neurological disorder and has been the second leading cause of disability worldwide for many years. The pathophysiology migraines complicated, most available medications have unpleasant side effects. Therefore, it essential to understand mechanism migraine develop potential preventive therapeutic agents. Studies confirmed that traditional Chinese medicine (TCM) can alleviate by reducing neuroinflammation, oxidative stress, apoptosis regulating neurotransmitters vascular function. Starting from pathophysiological process migraine, this review summarizes mechanisms which TCM improves neurovascular function after provide clues reference clinical application in prevention treatment guide further research development new drugs.
