Breaking the Cycle, Cholesterol Cycling, and Synapse Damage in Response to Amyloid-ß [PDF]
, 2017 Soluble amyloid-β (Aβ) oligomers, a key driver of pathogenesis in Alzheimer disease, bind to cellular prion proteins (PrPC) expressed on synaptosomes resulting in increased cholesterol concentrations, movement of cytoplasmic phospholipase A2 (cPLA2) to ...

Effects of Plasmin on von Willebrand Factor and Platelets: A Narrative Review
TH Open, 2018 Plasmin is the major fibrinolytic protease responsible for dissolving thrombi by cleavage of its primary substrate fibrin. In addition, emerging evidence points to other roles of plasmin: (1) as a back-up for ADAMTS13 in proteolysis of ultra-large von ...

Autophagy controls the induction and developmental decline of NMDAR-LTD through endocytic recycling
Nature Communications, 2020 NMDA receptor-dependent long-term depression (NMDAR-LTD) is a form of synaptic plasticity mediated by reduced recycling of AMPA receptors to the plasma membrane.

Enhancement of synchronization in a hybrid neural circuit by spike timing dependent plasticity [PDF]
, 2003 Synchronization of neural activity is fundamental for many functions of the brain. We demonstrate that spike-timing dependent plasticity (STDP) enhances synchronization (entrainment) in a hybrid circuit composed of a spike generator, a dynamic clamp ...

Biochemistry and Molecular Biology Education, 2009 AbstractDiverse biological data may be used to create illustrations of molecules in their cellular context. I describe the scientific results that support a recent textbook illustration of the neuromuscular synapse. The image magnifies a portion of the synapse at one million times, showing the location and the form of individual macromolecules. Results

IgSF21 promotes differentiation of inhibitory synapses via binding to neurexin2α
Nature Communications, 2017 Molecular mechanisms regulating the development of inhibitory synapses are poorly understood. Here the authors show that IgSF21 interacts with neurexin2α to induce presynaptic differentiation of inhibitory synapses, and that mice lacking IgSF21 exhibit ...

Activity-dependent regulation of mitochondrial motility in developing cortical dendrites
eLife, 2021 Developing neurons form synapses at a high rate. Synaptic transmission is very energy-demanding and likely requires ATP production by mitochondria nearby.

Synapse elimination and learning rules co-regulated by MHC class I H2-Db. [PDF]
, 2014 The formation of precise connections between retina and lateral geniculate nucleus (LGN) involves the activity-dependent elimination of some synapses, with strengthening and retention of others. Here we show that the major histocompatibility complex (MHC)
