ABSTRACT Depressive symptoms are common in Parkinson's disease (PD), but the pathophysiology and neural basis underlying depression PD is not well understood. Abnormal functional connectivity of amygdala with various cortical subcortical areas has been observed major depressive disorder, indicating that dysfunction corticolimbic network may be involved pathogenesis disorder. However, little known about alterations depressed patients. In present study, 20 patients, 40 nondepressed 43 matched...

Depressive symptoms are common in Parkinson's disease (PD), but the neurophysiological mechanisms of depression PD poorly understood. The current study attempted to examine disrupted spontaneous local brain activities and functional connectivities that underlie PD. We recruited a total 20 depressed patients (DPD), 40 non-depressed (NDPD) 43 matched healthy controls (HC). All subjects underwent neuropsychological tests resting-state fMRI scanning. between-group differences amplitude low...

Giant axonal neuropathy (GAN), an autosomal recessive disorder caused by mutations in GAN, is characterized cytopathologically cytoskeletal abnormality. Based on its sequence, gigaxonin contains NH2-terminal BTB domain followed six kelch repeats, which are believed to be important for protein–protein interactions (Adams, J., R. Kelso, and L. Cooley. 2000. Trends Cell Biol. 10:17–24.). Here, we report the identification of a neuronal binding partner gigaxonin. Results obtained from yeast...

Rap1 transduces nerve growth factor (NGF)/tyrosine receptor kinase A (TrkA) signaling in early endosomes, leading to sustained activation of the p44/p42 mitogen-activated protein kinases (MAPK1/2). However, mechanisms by which NGF, TrkA and are trafficked endosomes poorly defined. We investigated trafficking PC12 cells cultured rat dorsal root ganglion (DRG) neurons. Herein, we show a role for both microtubule- dynein-based transport NGF through MAPK1/2. treatment resulted perinuclear region...

Abstract The endosomal trafficking pathways are essential for many cellular activities. They also important targets by intracellular pathogens. Key regulators of the include retromer complex and sorting nexins (SNXs). Chlamydia trachomatis effector protein IncE directly components SNX5 SNX6 suppresses retromer-mediated transport, but exact mechanism has remained unclear. We present crystal structure PX domain in with IncE, showing that binds to a highly conserved hydrophobic groove SNX5....

Disruption of the BPAG1 (bullous pemphigoid antigen 1) gene results in progressive deterioration motor function and devastating sensory neurodegeneration null mice. We have previously demonstrated that BPAG1n1 BPAG1n3 play important roles organizing cytoskeletal networks vivo. Here, we characterize functions a novel neuronal isoform, BPAG1n4. Results obtained from yeast two-hybrid screening, blot overlay binding assays, coimmunoprecipitations demonstrate BPAG1n4 interacts directly with...

Appropriate clearance of apoptotic cells (cell corpses) is an important step programmed cell death. Although genetic and biochemical studies have identified several genes that regulate the engulfment corpses, how these are degraded after being internalized in engulfing remains elusive. Here, we show VPS-18, Caenorhabditis elegans homologue yeast Vps18p, critical to corpse degradation. VPS-18 expressed functions cells. Deletion vps-18 leads significant accumulation corpses not properly....

Brain-derived neurotrophic factor (BDNF) binds to its cell surface receptor TrkB regulate differentiation, development, synaptic plasticity, and functional maintenance of neuronal cells. Binding BDNF triggers dimerization autophosphorylation, which provides docking sites for adaptor proteins recruit activate downstream signaling molecules. The molecular mechanisms underlying BDNF–TrkB endocytic trafficking crucial spatiotemporal control pathways remain be elucidated. Here we show that...

Abstract The alterations of interhemispheric resting-state functional connectivity (FC) in Parkinson’s disease (PD) with depression remain unclear, so we aimed to explore the differences FC between PD and without depression. Twenty-one depressed (DPD) patients, 49 non-depressed (NDPD) patients 50 matched healthy controls (HC) participated this study. Resting-state magnetic resonance imaging (fMRI) data were analyzed voxel-mirrored homotopic (VMHC) approach. DPD showed lower VMHC values...

Retrograde axonal transport plays an important role in the maintenance of neuronal functions, but mechanism is poorly defined partly because constituents retrograde system and their interactions have yet to be elucidated. Of special interest how dynein/dynactin motor proteins interact with membrane cargoes. Here, we report that endosomal vesicle protein, termed retrolinkin, functions as a receptor tethering vesicles through BPAG1n4. Retrolinkin, protein highly enriched endosomes, binds...

HPS6 was originally identified as a subunit of the BLOC-2 protein complex which is involved in biogenesis lysosome-related organelles (LRO). Here, we demonstrate that directly interacts with p150Glued dynein–dynactin motor and acts cargo adaptor for retrograde to mediate transport lysosomes from cell periphery perinuclear region. Small interference RNA (siRNA)-mediated knockdown HeLa cells not only partially blocks centripetal movement but also causes delay lysosome-mediated degradation....

Induction of long-term potentiation (LTP) in excitatory neurons triggers a large transient increase the volume dendritic spines followed by decays to sustained size expansion, process termed structural LTP (sLTP) that contributes cellular basis learning and memory. Although mechanisms regulating early phases sLTP have been studied intensively, how acute spine enlargement immediately after stimulation is achieved remains elusive. Here, we report endophilin A1 orchestrates membrane dynamics...
