Developmental Changes of Human Neural Progenitor Cells Grafted into the Ventricular System and Prefrontal Cortex of Mouse Brain in Utero

open access: yesCells, 2023
The transplantation of neural progenitors into a host brain represents a useful tool to evaluate the involvement of cell-autonomous processes and host local cues in the regulation of neuronal differentiation during the development of the mammalian brain.

Functional maturation of human iPSC-derived pyramidal neurons in vivo is dependent on proximity with the host tissue

open access: yesFrontiers in Cellular Neuroscience, 2023
Human induced pluripotent stem cells (hiPSCs) have been used extensively in vitro to model early events in neurodevelopment. Because of a number of shortcomings, previous work has established a potential to use these cells in vivo after transplantation ...

Fueling Synapses [PDF]

open access: yesCell, 2004
The transmission of information across neuronal synapses is an energetically taxing business. Sheng and colleagues monitored the localization of mitochondria following different levels of synaptic activation and discovered that these organelles change their distribution in interesting ways, stalling near synapses when neurons are activated and ...

Pathological and Synaptic Morphological Changes of the Olfactory Bulb in APP/PS1 Model Mice at Different Ages and the Intervention Effect of Memantine

open access: yesShiyan dongwu yu bijiao yixue, 2022
Objective To compare and explore the histopathological and ultrastructural characteristics of the olfactory bulb in 6- and 12-month-old APP/PS1 double-transgenic mice and their spatial learning and memory ability, as well as the effects of memantine ...

Systemic Inflammation Accelerates Changes in Microglial and Synaptic Markers in an Experimental Model of Chronic Neurodegeneration

open access: yesFrontiers in Neuroscience, 2022
Bacterial infections are a common cause of morbidity and mortality in the elderly, and particularly in individuals with a neurodegenerative disease. Experimental models of neurodegeneration have shown that LPS-induced systemic inflammation increases ...

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

open access: yesCells, 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 ...

Decoding Synapses [PDF]

open access: yesThe Journal of Neuroscience, 1996
The strength of many synapses is modified by various use and time-dependent processes, including facilitation and depression. A general description of synaptic transfer characteristics must account for the history-dependence of synaptic efficacy and should be able to predict the postsynaptic response to any temporal pattern of presynaptic activity.

Rostral and caudal basolateral amygdala engage distinct circuits in the prelimbic and infralimbic prefrontal cortex

open access: yeseLife, 2022
Connections from the basolateral amygdala (BLA) to medial prefrontal cortex (PFC) regulate memory and emotion and become disrupted in neuropsychiatric disorders.

Interaction and Subcellular Association of PRRT1/SynDIG4 With AMPA Receptors

open access: yesFrontiers in Synaptic Neuroscience, 2021
AMPA receptors (AMPAR) are organized into supramolecular complexes in association with other membrane proteins that provide exquisite regulation of their biophysical properties and subcellular trafficking.
