Connexin36 Expression in the Mammalian Retina: A Multiple-Species Comparison

Frontiers in Cellular Neuroscience, 2017
Much knowledge about interconnection of human retinal neurons is inferred from results on animal models. Likewise, there is a lack of information on human retinal electrical synapses/gap junctions (GJ).

Super-resolution imaging and estimation of protein copy numbers at single synapses with DNA-PAINT [PDF]

, 2019
In the brain, the strength of each individual synapse is defined by the complement of proteins present or the "local proteome." Activity-dependent changes in synaptic strength are the result of changes in this local proteome and posttranslational protein

Alpha Waves as a Neuromarker of Autism Spectrum Disorder: The Challenge of Reproducibility and Heterogeneity

Frontiers in Neuroscience, 2018
Background: There is no consensus in the literature concerning the presence of abnormal alpha wave profiles in patients with autism spectrum disorder (ASD).

Associative memory neurons of encoding multi-modal signals are recruited by neuroligin-3-mediated new synapse formation

eLife, 2023
The joint storage and reciprocal retrieval of learnt associated signals are presumably encoded by associative memory cells. In the accumulation and enrichment of memory contents in lifespan, a signal often becomes a core signal associatively shared for ...

Microglia remodel synapses by presynaptic trogocytosis and spine head filopodia induction

Nature Communications, 2017
Microglia are highly motile glial cells that are proposed to mediate synaptic pruning during neuronal circuit formation. Disruption of signaling between microglia and neurons leads to an excess of immature synaptic connections, thought to be the result ...

Structural basis of astrocytic Ca2+ signals at tripartite synapses

Nature Communications, 2020
Astrocytic Ca2+ signals can be fast and local, supporting the idea that astrocytes have the ability to regulate single synapses. However, the anatomical basis of such specific signaling remains unclear, owing to difficulties in resolving the spongiform ...

Autophagy at the synapse [PDF]

Neuroscience Letters, 2019
As the sites of communication between neurons, synapses depend upon precisely regulated protein-protein interactions to support neurotransmitter release and reception. Moreover, neuronal synapses typically exist great distances (i.e. up to meters) away from cell bodies, which are the sources of new proteins and the major sites of protein degradation ...

Intracellular Trafficking Mechanisms of Synaptic Dysfunction in Alzheimer’s Disease

Frontiers in Cellular Neuroscience, 2020
Alzheimer’s disease (AD) is the most common neurodegenerative disease characterized by progressive memory loss. Although AD neuropathological hallmarks are extracellular amyloid plaques and intracellular tau tangles, the best correlate of disease ...

Microglia Depletion-Induced Remodeling of Extracellular Matrix and Excitatory Synapses in the Hippocampus of Adult Mice

Cells, 2021
The extracellular matrix (ECM) plays a key role in synaptogenesis and the regulation of synaptic functions in the central nervous system. Recent studies revealed that in addition to dopaminergic and serotoninergic neuromodulatory systems, microglia also ...
