Extracellular biotransformation of beta-endorphin in rat striatum and cerebrospinal fluid.
Numerous studies have investigated the behavioural effects of beta-endorphin, both endogenous and exogenously applied. However, the potential for biotransformation of beta-endorphin in the extracellular space of the brain has not been previously directly addressed in vivo. Utilising microinfusion/microdialysis and matrix-assisted laser desorption/ionisation mass spectrometry, we investigated be...
متن کاملCerebrospinal fluid and plasma β‐endorphin levels in children with cerebral malaria
OBJECTIVES Cerebral malaria (CM) is the most lethal form of malaria, yet its pathogenesis is not fully understood. Cytoadherence, sequestration, alterations in cytokine expression, inflammation, and microvascular obstruction are all hypothesized to be important in the aetio-pathogenesis of coma which characterizes cerebral malaria and the death which sometimes result. Beta (β)-endorphin has bee...
متن کاملRadioimmunoassay of beta-endorphin in ventricular and lumbar cerebrospinal fluid.
We describe a sensitive beta-endorphin (beta-EP) radioimmunoassay specific for beta-EP 1-31 applied to human ventricular and lumbar cerebrospinal fluid (CSF). Specificity was documented by reversed-phase HPLC of CSF pools. Simultaneous ventricular and lumbar CSF samples from 13 patients suspected of having normal-pressure hydrocephalus showed median beta-EP values of 2.2 (range 1.7-4.0) and 4.8...
متن کاملAnalysis of extracellular RNA in cerebrospinal fluid
We examined the extracellular vesicle (EV) and RNA composition of pooled normal cerebrospinal fluid (CSF) samples and CSF from five major neurological disorders: Alzheimer's disease (AD), Parkinson's disease (PD), low-grade glioma (LGG), glioblastoma multiforme (GBM), and subarachnoid haemorrhage (SAH), representing neurodegenerative disease, cancer, and severe acute brain injury. We evaluated:...
متن کاملA Modified Method for Cerebrospinal Fluid Collection in Anesthetized Rat and Evaluation of the Efficacy
Dear editor: We would like to present a modified method for cerebrospinal fluid collection in anesthetized rat. This method is easy and applicable in many laboratories interested by research on cellular and molecular effects of CSF on different pathways.
