AB - Intracellular sigma-1 receptors (sigma1 receptors) have a versatile function through the regulation of lipid rafts, neuroreceptors and ion channels, and can influence signal transduction and neuronal plasticity. Since decreased activity of sigma1 receptors is a common pathological feature in the early stages of many neurological diseases, sigma1 receptor agonists may represent a promising therapeutic tool for the treatment of these disorders. In this study, we aimed to comprehensively investigate the potential protective effects of the novel synthetic sigma1 receptor agonist (S)-L1 against endothelial endoplasmic reticulum (ER) stress and cerebral ischemia. In binding affinity experiments, we showed that (S)-L1 has a high affinity and selectivity for sigma1 receptor with virtually no affinity for any of the other receptors tested. Next, (S)-L1 exerted protection against endoplasmic reticulum stress in human brain endothelial cells, consistent with the localization of sigma1 receptor in endothelial cells. Furthermore, (S)-L1 penetration was demonstrated across the cell culture model of the blood-brain barrier, providing a rationale for neuronal action in addition to endothelial protection. Finally, (S)-L1 inhibited spreading depolarization, suppressed apoptosis and rescued astrocytes in a rat model of cerebral ischemia. Based on our results, (S)-L1 exerts a protective effect on both brain endothelial cells and neural tissue. Moreover, since these experiments revealed no affinity for serotonergic receptors, the compound holds promise as an adjuvant therapy for the treatment of cerebrovascular disease without potential psychedelic side effects.

AB - Alzheimer’s disease (AD) is an incurable, progressive neurodegenerative disorder. AD is a complex and multifactorial disease that is responsible for 60–80% of dementia cases. Aging, genetic factors, and epigenetic changes are the main risk factors for AD. Two aggregation-prone proteins play a decisive role in AD pathogenesis: β-amyloid (Aβ) and hyperphosphorylated tau (pTau). Both of them form deposits and diffusible toxic aggregates in the brain. These proteins are the biomarkers of AD. Different hypotheses have tried to explain AD pathogenesis and served as platforms for AD drug research. Experiments demonstrated that both Aβ and pTau might start neurodegenerative processes and are necessary for cognitive decline. The two pathologies act in synergy. Inhibition of the formation of toxic Aβ and pTau aggregates has been an old drug target. Recently, successful Aβ clearance by monoclonal antibodies has raised new hopes for AD treatments if the disease is detected at early stages. More recently, novel targets, e.g., improvements in amyloid clearance from the brain, application of small heat shock proteins (Hsps), modulation of chronic neuroinflammation by different receptor ligands, modulation of microglial phagocytosis, and increase in myelination have been revealed in AD research.

S1R plays a role in the pathomechanism of diseases and the regulation of neurotransmitters. Fluvoxamine can bind to S1R and reduce the serotonin uptake of neurons and platelets. We therefore hypothesized that platelets express S1R, which can modify platelet function. The expression of the SIGMAR1 gene in rat platelets was examined with a reverse transcription polymerase chain reaction and a quantitative polymerase chain reaction. The receptor was also visualized by immunostaining and confocal laser scanning microscopy. The effect of S1R agonist PRE-084 on the eicosanoid synthesis of isolated rat platelets and ADP- and AA-induced platelet aggregation was examined. S1R was detected in rat platelets both at gene and protein levels. Pretreatment with PRE-084 of resting platelets induced elevation of eicosanoid synthesis. The rate of elevation in thromboxane B2 and prostaglandin D2 synthesis was similar, but the production of prostaglandin E2 was higher. The concentration-response curve showed a sigmoidal form. The most effective concentration of the agonist was 2 µM. PRE-084 increased the quantity of cyclooxygenase-1 as detected by ELISA. PRE-084 also elevated the ADP- and AA-induced platelet aggregation. S1R of platelets might regulate physiological or pathological functions. © 2021 Taylor & Francis Group, LLC.

AB - Neurogenesis plays a crucial role in cognitive processes. During aging and in Alzheimer’s disease (AD), altered neurogenesis and neuroinflammation are evident both in C57BL/6J, APPSwe/PS1dE9 (Tg) mice and humans. AD pathology may slow down upon drug treatment, for example, in a previous study of our group P33, a putative neuroprotective agent was found to exert advantageous effects on the elevated levels of APP, Aβ, and neuroinflammation. In the present study, we aimed to examine longitudinal alterations in neurogenesis, neuroinflammation and AD pathology in a transgenic (Tg) mouse model, and assessed the putative beneficial effects of long-term P33 treatment on AD-specific neurological alterations. Hippocampal cell proliferation and differentiation were significantly reduced between 8 and 12 months of age. Regarding neuroinflammation, significantly elevated astrogliosis and microglial activation were observed in 6- to 7-month-old Tg animals. The amounts of the molecules involved in the amyloidogenic pathway were altered from 4 months of age in Tg animals. P33-treatment led to significantly increased neurogenesis in 9-month-old animals. Our data support the hypothesis that altered neurogenesis may be a consequence of AD pathology. Based on our findings in the transgenic animal model, early pharmacological treatment before the manifestation of AD symptoms might ameliorate neurological decline. LA - English DB - MTMT ER -
