The spine problem: finding a function for dendritic spines

open access: yesFrontiers in Neuroanatomy, 2014
Why do neurons have dendritic spines? This question-the heart of what Yuste calls "the spine problem"-presupposes that why-questions of this sort have scientific answers: that empirical findings can favor or count against claims about why neurons have spines. Here we show how such questions can receive empirical answers.

ApoE receptor 2 regulates synapse and dendritic spine formation.

open access: yesPLoS ONE, 2011
BackgroundApolipoprotein E receptor 2 (ApoEr2) is a postsynaptic protein involved in long-term potentiation (LTP), learning, and memory through unknown mechanisms.

Calcium Dynamics in Dendritic Spines and Spine Motility [PDF]

open access: yesBiophysical Journal, 2004
A dendritic spine is an intracellular compartment in synapses of central neurons. The role of the fast twitching of spines, brought about by a transient rise of internal calcium concentration above that of the parent dendrite, has been hitherto unclear.

Synapses and Dendritic Spines as Pathogenic Targets in Alzheimer’s Disease

open access: yesNeural Plasticity, 2012
Synapses are sites of cell-cell contacts that transmit electrical or chemical signals in the brain. Dendritic spines are protrusions on dendritic shaft where excitatory synapses are located.

Chronic low-dose Δ9-tetrahydrocannabinol (THC) treatment stabilizes dendritic spines in 18-month-old mice

open access: yesScientific Reports, 2023
Cognitive functions decline during aging. This decline could be caused by changes in dendritic spine stability and altered spine dynamics. Previously, we have shown that a low dose chronic THC treatment improves learning abilities in old whereas impairs ...

Co-exposure to low-dose lead, cadmium, and mercury promotes memory deficits in rats: Insights from the dynamics of dendritic spine pruning in brain development

open access: yesEcotoxicology and Environmental Safety, 2023
Lead (Pb), cadmium (Cd), and mercury (Hg) are environmentally toxic heavy metals that can be simultaneously detected at low levels in the blood of the general population. Although our previous studies have demonstrated neurodevelopmental toxicity upon co-

Calcium Signaling in Dendritic Spines [PDF]

open access: yesCold Spring Harbor Perspectives in Biology, 2012
Calcium (Ca(2+)) is a ubiquitous signaling molecule that accumulates in the cytoplasm in response to diverse classes of stimuli and, in turn, regulates many aspects of cell function. In neurons, Ca(2+) influx in response to action potentials or synaptic stimulation triggers neurotransmitter release, modulates ion channels, induces synaptic plasticity ...

Hippocampal CA1 Pyramidal Neurons of Mecp2 Mutant Mice Show a Dendritic Spine Phenotype Only in the Presymptomatic Stage

open access: yesNeural Plasticity, 2012
Alterations in dendritic spines have been documented in numerous neurodevelopmental disorders, including Rett Syndrome (RTT). RTT, an X chromosome-linked disorder associated with mutations in MECP2, is the leading cause of ...

A genetic labeling system to study dendritic spine development in zebrafish models of neurodevelopmental disorders

open access: yesDisease Models & Mechanisms, 2022
Dendritic spines are the principal site of excitatory synapse formation in the human brain. Several neurodevelopmental disorders cause spines to develop abnormally, resulting in altered spine number and morphology.
