Although much of the focus regarding the induction of Cox-2 in the brain has been centered on neuroinflammation-related neurodegenerative and psychiatric disorders, some evidence also suggests that Cox-2 release during neuronal signaling may be pivotal for the fine tuning of cortical networks to regulate behavior. This review compiles the evidence supporting the homeostatic role of neuronal Cox-2 in synaptic transmission and plasticity, since neuroinflammation is originally triggered by the induction of glial Cox-2 expression. The goal is to provide perspective on the roles of Cox-2 beyond neuroinflammation, such as those played in memory and anxiety, and whose evidence is still scant. WHO grades II (atypical) and III (malignant) meningiomas are associated with significant morbidity and mortality. The role of adjuvant radiotherapy (RT) in management remains controversial. The goal of this study was to evaluate the impact of adjuvant RT on 5-year survival in patients with atypical and malignant meningiomas. We secondarily aimed to assess contemporary practice patterns and the impact of sociodemographic factors on outcome. We queried the National Cancer Database for patients ≥ 18years of age with cranial atypical or malignant meningiomas from 2010 through 2015 who underwent surgical resection with or without adjuvant radiotherapy. Subjects with unknown WHO grade or radiation status and those not receiving any surgical procedure were excluded from analysis. The study includes 7486 patients, 6788 with atypical and 698 with malignant meningiomas. Overall 5-year survival was 76.9% (95% CI 75.5-78.3%) and 43.3% (95% CI 38.8-48.2%) among patients with WHO grades II and III meningiomas, respecd III intracranial meningiomas regardless of the extent of resection. There is poor utilization of adjuvant RT for patients with grades II and III meningiomas likely due to a paucity of quality data on the subject. These findings will be strengthened with prospective data evaluating the role of adjuvant RT. Adjuvant RT may correlate with improved overall survival in patients with grades II and III intracranial meningiomas regardless of the extent of resection. There is poor utilization of adjuvant RT for patients with grades II and III meningiomas likely due to a paucity of quality data on the subject. These findings will be strengthened with prospective data evaluating the role of adjuvant RT.Due to molecular mimicry, maternal antibacterial antibodies are suspected to promote neurodevelopmental changes in the offspring that finally can cause disorders like autism and schizophrenia. Using a human first trimester prenatal brain multiprotein array (MPA), we demonstrate here that antibodies to the digestive tract bacteria Helicobacter pylori (α-HPy) and Campylobacter jejuni (α-CJe) interact with different synaptic proteins, including the calcium sensor synaptotagmin 5 (Syt5). Interactions of both antisera with Syt5 were confirmed by Western blot with a HEK293-cells overexpression lysate of this protein. Immunofluorescence and Western blotting revealed SiMa cells to express Syt5, which also co-migrated with a band/spot labeled by either α-HPy or α-CJe. Functionally, a 12-h pretreatment of SiMa cells with 10 μg/ml of either α-HPy or α-CJe resulted in a significant reduction of acetylcholine(ACh)-dependent calcium signals as compared to controls. Also ACh-dependent vesicle recycling was significantly reduced in cells pretreated with either α-HPy or α-CJe. Similar effects were observed upon pretreatment of SiMa cells with Syt5-specific antibodies. In conclusion, the present study supports the view that prenatal maternal antibacterial immune responses towards HPy and by this to Syt5 are able to cause functional changes, which in the end might contribute also to neurodevelopmental disorders.Septal innervation of basal forebrain cholinergic neurons to the hippocampus is critical for normal learning and memory and is seve
