MARCKS for Maintenance in Dendritic Spines [PDF]

Neuron, 2005
Synapses in the brain must maintain a balance between learning-related plasticity and the stability necessary for reliable function. In this issue of Neuron, Calabrese and Halpain describe cell-transfection experiments implicating MARCKS, a protein that binds to both the cell surface and actin cytoskeleton, in the maintenance of dendritic spines.

Targeting Lactate and Lactylation in Cancer Metabolism and Immunotherapy

Advanced Science, EarlyView.
Lactate, once deemed a metabolic waste, emerges as a central regulator of cancer progression. This review elucidates how lactate and its epigenetic derivative, protein lactylation, orchestrate tumor metabolism, immune suppression, and therapeutic resistance.

Barriers in the Brain: Resolving Dendritic Spine Morphology and Compartmentalization

Frontiers in Neuroanatomy, 2014
Dendritic spines are micron-sized protrusions that harbor the majority of excitatory synapses in the central nervous system. The head of the spine is connected to the dendritic shaft by a 50-400 nm thin membrane tube, called the spine neck, which has ...

Psychedelics Promote Structural and Functional Neural Plasticity. [PDF]

, 2018
Atrophy of neurons in the prefrontal cortex (PFC) plays a key role in the pathophysiology of depression and related disorders. The ability to promote both structural and functional plasticity in the PFC has been hypothesized to underlie the fast ...

Functional Mapping of Neurodevelopmental Disease Pathways to Key Neurodevelopmental Processes Represented in the Developmental Neurotoxicity In Vitro Testing Battery

Advanced Science, EarlyView.
Human‐relevant methods are essential for modern chemical safety assessment. This study helps define the capabilities and boundaries of an in vitro testing battery for developmental neurotoxicity by exploring its biological applicability domain. By linking neurodevelopmental disease‐related pathways to key neurodevelopmental processes, the work enhances

Passive immunotherapy rapidly increases structural plasticity in a mouse model of Alzheimer disease

Neurobiology of Disease, 2009
Senile plaque-associated changes in neuronal connectivity such as altered neurite trajectory, dystrophic swellings, and synapse and dendritic spine loss are thought to contribute to cognitive dysfunction in Alzheimer's disease and mouse models ...

The schizophrenia-associated missense variant rs13107325 regulates dendritic spine density

Translational Psychiatry, 2022
The missense variant rs13107325 (C/T, p.Ala391Thr) in SLC39A8 consistently showed robust association with schizophrenia in recent genome-wide association studies (GWASs), suggesting the potential pathogenicity of this non-synonymous risk variant ...

Structural plasticity of dendritic spines [PDF]

Current Opinion in Neurobiology, 2012
Dendritic spines are small mushroom-like protrusions arising from neurons where most excitatory synapses reside. Their peculiar shape suggests that spines can serve as an autonomous postsynaptic compartment that isolates chemical and electrical signaling.

Synchrotron XRF Imaging Reveals Manganese Accumulation in the Golgi and Post‐Synapses of Neurons and Enhanced Uptake in Astrocytes

Advanced Science, EarlyView.
Despite widespread exposure, the mechanisms of manganese neurotoxicity remain poorly understood. Using correlative cryogenic fluorescence and synchrotron X‐ray fluorescence imaging techniques, we show that the Golgi apparatus is the primary accumulation site for manganese in both neurons and astrocytes, and that manganese targets the neuronal ...
