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).

Neuromorphic functionality of ferroelectric domain walls

Neuromorphic Computing and Engineering, 2023
Mimicking and replicating the function of biological synapses with engineered materials is a challenge for the 21st century. The field of neuromorphic computing has recently seen significant developments, and new concepts are being explored. One of these

The Immunological Synapse [PDF]

Cancer Immunology Research, 2003
AbstractThe molecular interactions underlying regulation of the immune response take place in a nanoscale gap between T cells and antigen-presenting cells, termed the immunological synapse. If these interactions are regulated appropriately, the host is defended against a wide range of pathogens and deranged host cells.

Monoacylated Cellular Prion Proteins Reduce Amyloid-β-Induced Activation of Cytoplasmic Phospholipase A2 and Synapse Damage

Biology, 2015
Alzheimer’s disease (AD) is a progressive neurodegenerative disease characterized by the accumulation of amyloid-β (Aβ) and the loss of synapses. Aggregation of the cellular prion protein (PrPC) by Aβ oligomers induced synapse damage in cultured neurons.

Neuron Class and Target Variability in the Three-Dimensional Localization of SK2 Channels in Hippocampal Neurons as Detected by Immunogold FIB-SEM

Frontiers in Neuroanatomy, 2021
Small-conductance calcium-activated potassium (SK) channels are crucial for learning and memory. However, many aspects of their spatial organization in neurons are still unknown.

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 ...

Transient oxytocin signaling primes the development and function of excitatory hippocampal neurons

eLife, 2017
Beyond its role in parturition and lactation, oxytocin influences higher brain processes that control social behavior of mammals, and perturbed oxytocin signaling has been linked to the pathogenesis of several psychiatric disorders.

Exercise Intervention Promotes the Growth of Synapses and Regulates Neuroplasticity in Rats With Ischemic Stroke Through Exosomes

Frontiers in Neurology, 2021
Background: Stroke is the leading cause of death and disability. Exercise produces neuroprotection by improving neuroplasticity. Exercise can induce exosome production.
