This study reveals the existence of a CD40L/CD40/TRAF axis in EOCs and shows that sCD40L increases the pro-angiogenic function of EOCs on cultured HUVECs by inducing a significant increase in MMP-9 release via, at
least, the p38 MAPK signaling pathway.”
“Protein tau plays a pivotal role in the pathophysiology of Alzheimer’s disease, where its hyperphos-phorylation promotes aggregation and microtubule destabilization. Tau undergoes alternative splicing which generates six isoforms in the human brain, due to inclusion/exclusion of exons 2, 3 and 10. Dysregulation of the splicing process of tau exon 10 is sufficient to cause tauopathy and has shown to be influenced by beta-amyloid peptides, but splicing of other exons is less studied. We studied
the effects of beta-amyloid(42) in the alternative splicing of tau exons 2/3 and 6, using untreated and Nerve Angiogenesis inhibitor Growth Factor-induced PC12 cells. Beta-amyloid exposure caused formed cell processes to retract in differentiated cells and altered the expression of exons 2/3 in both undifferentiated and differentiated cells. Expression of exon 6 was repressed in undifferentiated cells only. Our results suggest that beta-amyloid interferes with the splicing process of exons 2/3, favoring their exclusion and thus the expression of immature tau isoforms that are less efficient in stabilizing microtubules and may also be more prone to hyperphosphorylation. The molecular mechanism for this amyloid-tau interaction remains GSK1904529A to be determined, but may have potential
implications for the understanding Selleckchem MAPK Inhibitor Library of the underlying neuropathological processes in Alzheimer’s disease.”
“We undertook a systematic search and review of individual, family, community, and societal risk and protective factors for mental health in children and adolescents who are forcibly displaced to high-income countries. Exposure to violence has been shown to be a key risk factor, whereas stable settlement and social support in the host country have a positive effect on the child’s psychological functioning. Further research is needed to identify the relevant processes, contexts, and interplay between the many predictor variables hitherto identified as affecting mental health vulnerability and resilience. Research designs are needed that enable longitudinal investigation of individual, community, and societal contexts, rather than designs restricted to investigation of the associations between adverse exposures and psychological symptoms. We emphasise the need to develop comprehensive policies to ensure a rapid resolution of asylum claims and the effective integration of internally displaced and refugee children.”
