“The pathobiology of chronic pancreatitis (CP) remains enigmatic despite remarkable progress made recently

in uncovering key mechanisms involved in the initiation and progression of the disease. CP is increasingly thought of as a multifactorial disorder. Apoptosis plays a role in parenchymal destruction, the pathological hallmark of CP. The apoptotic mechanisms preferentially target the exocrine compartment, leaving endocrine islets relatively intact for a prolonged period. Exocrine cells shed

their ‘immunoprivileged’ status, express death receptors, and are rendered susceptible to apoptosis Elafibranor nmr induced by death ligands on infiltrating lymphocytes, and released locally by activated pancreatic stellate cells. Islet cells retain their ‘immunoprivileged’ status and activate anti-apoptotic programs through NF-kappa B. Ductal changes, including distortion, dilatation, and pancreatic ductal hypertension in the setting of CP, induce genomic damage and increased cell turnover. In addition, signaling mechanisms that play a role in the development of embryonic pancreas are reinstated, thus, playing a role in repair, regeneration, and transformation. This, in turn, leads to acino-ductal metaplasia (ADM) and pancreatic intraepithelial neoplasia (PanIN). Some of these pathways are see more activated in pancreatic cancer. We attempt to integrate the current knowledge and major concepts in the pathogenesis of CP and to explain the mechanism of differential cell loss. We also discuss the possible implications of signaling pathway activation in pancreatic inflammation, relevant to the cellular transformation that leads to pancreatic neoplasia.”
“Deep brain stimulation (DBS) of the MK5108 clinical trial basal ganglia motor circuitry is a highly effective treatment for the debilitating

motor symptoms of Parkinson’s disease (PD). However, recent findings have indicated promising potential for PD therapy with DBS in brain structures outside the basal ganglia. For example, high frequency stimulation of the posterior hypothalamic nucleus (PH) can reverse haloperidol-induced akinesia in rats [Jackson J, Young CK, Hu B, Bland BH (2008) High frequency stimulation of the posterior hypothalamic nucleus restores movement and reinstates hippocampal-striatal theta coherence following haloperidol-induced catalepsy. Exp Neurol 213:210-219]. In the current study, we used the bilateral 6-hydroxydopamine lesion model of Parkinsonian akinesia in male Long-Evans rats to further explore the efficacy of PH DBS. The application of PH DBS in lesioned animals reversed akinesia in an active avoidance paradigm with increased latency compared to pre-lesion performance.
