A Mathematical Model of Tripartite Synapse: Astrocyte Induced Synaptic Plasticity
, 2012 In this paper we present a biologically detailed mathematical model of tripartite synapses, where astrocytes modulate short-term synaptic plasticity. The model consists of a pre-synaptic bouton, a post-synaptic dendritic spine-head, a synaptic cleft and ...

Shortened primary cilium length and dysregulated Sonic hedgehog signaling in Niemann-Pick C1 disease [PDF]
, 2017 The Niemann-Pick type C1 (NPC1) disease is a neurodegenerative lysosomal storage disorder due to mutations in the NPC1 gene, encoding a transmembrane protein related to the Sonic hedgehog receptor, Patched, and involved in intracellular trafficking of ...

Advanced Science, EarlyView.Chronic periodontitis elevates circulating CRP, which enters the hippocampus to upregulate BMP4 in oligodendrocyte precursor cells (OPCs), thereby impairing neurogenesis and inducing anxiety/depression‐like behaviors in rats. Counteracting this pathway, CRP deficiency helps confer functional resilience to OPCs.

Advanced Science, EarlyView.Emerging evidence suggests that intraneuronal Aβ accumulation represents an early pathogenic event in Alzheimer's disease (AD). Using Drosophila AD model, this study shows that a nonsecreted serine protease Yip7 physically interacts with Aβ. This causes intraneuronal Aβ accumulation but surprisingly reduces the associated neurotoxicity, arguing that ...

Journal of Extracellular VesiclesC1q is released by microglia, localizes on weak synapses and acts as a tag for microglial synaptic pruning. However, how C1q tags synapses during the pruning period remains to be fully elucidated.

Axonal amyloid precursor protein and its fragments undergo somatodendritic endocytosis and processing. [PDF]
, 2015 Deposition of potentially neurotoxic Aβ fragments derived from amyloid precursor protein (APP) at synapses may be a key contributor to Alzheimer's disease.

Advanced Science, EarlyView.Soybean employs its circadian clock, governed by GmCCA1, to rhythmically defend against soybean cyst nematodes. The pathogen retaliates by secreting the effector Hg4E02, which hijacks the clock to suppress defense and co‐opt the host's translation machinery for nutrient acquisition.

Munc13-1 and Munc18-1 together prevent NSF-dependent de-priming of synaptic vesicles
Nature Communications, 2017 The molecular mechanism underlying the generation and maintenance of the readily releasable pool composed of primed synaptic vesicles is only partially known.

Clarinet (CLA-1), a novel active zone protein required for synaptic vesicle clustering and release
eLife, 2017 Active zone proteins cluster synaptic vesicles at presynaptic terminals and coordinate their release. In forward genetic screens, we isolated a novel Caenorhabditis elegans active zone gene, clarinet (cla-1).
