Sphingolipids are ubiquitous building blocks of eukaryotic cell membranes that function as signaling molecules for regulating a diverse range cellular processes, including proliferation, growth, survival, immune-cell trafficking, vascular and epithelial integrity, inflammation. Recently, several studies have highlighted the pivotal role sphingolipids in neuroinflammatory regulation. multiple functions, induction expression various inflammatory mediators regulation neuroinflammation by directly effecting cells central nervous system. Accumulating evidence points to sphingolipid engagement disorders, Alzheimer's Parkinson's diseases. Abnormal alterations, which involves an increase ceramide decrease sphingosine kinase, observed during disease. These trends early disease development, thus highlight potential new therapeutic diagnostic target [BMB Reports 2020; 53(1): 28-34].

The most commonly used treatment for Parkinson’s disease (PD) is levodopa, prescribed in conjunction with carbidopa. Virtually all patients PD undergo dopamine replacement therapy using levodopa during the course of disease’s progression. However, despite fact that “gold standard” treatments and has ability to significantly alleviate symptoms, it comes side effects advanced PD. Levodopa remains current clinical choice patients, but approximately 80% treated develop levodopa-induced dyskinesia (LID) stages disease. A better understanding pathological mechanisms LID possible means improvement would improve outcome reduce complexity medication use, lower adverse effects, thus, improving quality life prolonging their cycle. This review assesses recent advancements underlying therapeutic management options available after emergence patients.

Abstract Deep Brain Stimulation can improve tremor, bradykinesia, rigidity, and axial symptoms in patients with Parkinson’s disease. Potentially, improving each symptom may require stimulation of different white matter tracts. Here, we study a large cohort (N = 237 from five centers) to identify tracts associated improvements the four domains. Tremor were connected primary motor cortex cerebellum. In contrast, are supplementary brainstem. Bradykinesia rigidity premotor cortices, respectively.

Abstract The basal ganglia are essential for executing motor actions. How the engage spinal networks has remained elusive. Medullary Chx10 gigantocellular (Gi) neurons required turning gait programs, suggesting that gaits organized by executed via this descending pathway. Performing deep brainstem recordings of Gi Ca 2+ activity in adult mice, we show striatal projection initiate a dominant crossed pathway to on contralateral side. Using intersectional viral tracing and cell-type-specific modulation, uncover principal ganglia–spinal cord locomotor asymmetries mice: → pontine reticular nucleus, oral part (PnO) cord. Modulating restricted PnO restores competence upon damage, dysfunction may contribute debilitating deficits observed Parkinson’s disease.
