Activation of acid‐sensing ion channels by carbon dioxide regulates amygdala synaptic protein degradation in memory reconsolidation

Molecular Brain, 2021
Reconsolidation has been considered a process in which a consolidated memory is turned into a labile stage. Within the reconsolidation window, the labile memory can be either erased or strengthened.

Loss of tumor necrosis factor (TNF)‐receptor 1 and TNF‐receptor 2 partially replicate effects of TNF deficiency on dendritic spines of granule cells in mouse dentate gyrus

Journal of Comparative Neurology, Volume 531, Issue 2, Page 281-293, February 2023., 2023
Hippocampal granule cells of adult mice lacking canonical TNF‐Rs were filled with Alexa568 and immunolabeled for Synaptopodin. Morphometric analysis of their spines revealed that TNF‐R mutants partially replicate changes previously reported for TNF‐deficient mice.

Presynaptic AMPA Receptors in Health and Disease [PDF]

Cells, 2021
AMPA receptors (AMPARs) are ionotropic glutamate receptors that play a major role in excitatory neurotransmission. AMPARs are located at both presynaptic and postsynaptic plasma membranes. A huge number of studies investigated the role of postsynaptic AMPARs in the normal and abnormal functioning of the mammalian central nervous system (CNS).

Cortical synapses of the world's smallest mammal: An FIB/SEM study in the Etruscan shrew

Journal of Comparative Neurology, Volume 531, Issue 3, Page 390-414, February 2023., 2023
The present work provides a quantitative dataset of synapses from the Etruscan shrew (the smallest known terrestrial mammal). We have identified common and differing principles of synaptic organization compared to other mammalian species. Abstract The main aim of the present study was to determine if synapses from the exceptionally small brain of the ...

AMPA receptor trafficking and learning [PDF]

European Journal of Neuroscience, 2010
AbstractIn the last few years it has become clear that AMPA‐type glutamate neurotransmitter receptors are rapidly transported into and out of synapses to strengthen or weaken their function. The remarkable dynamics of AMPA receptor (AMPAR) synaptic localization provides a compelling mechanism for understanding the cellular basis of learning and memory,

AMPA Receptor Function in Hypothalamic Synapses [PDF]

Frontiers in Synaptic Neuroscience, 2022
AMPA receptors (AMPARs) are critical for mediating glutamatergic synaptic transmission and plasticity, thus playing a major role in the molecular machinery underlying cellular substrates of memory and learning. Their expression pattern, transport and regulatory mechanisms have been extensively studied in the hippocampus, but their functional properties

Functional studies and distribution define a family of transmembrane AMPA receptor regulatory proteins [PDF]

, 2003
Functional expression of α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors in cerebellar granule cells requires stargazin, a member of a large family of four-pass transmembrane proteins.

Gating Modes in AMPA Receptors [PDF]

The Journal of Neuroscience, 2010
AMPA receptors are ligand-gated ion channels that show multiple conductance levels, indicating that gating of individual AMPA subunits is to some extent independent of the other subunits. To study AMPAR subunit interactions during activation gating, we recorded from single channels in the absence of channel block and desensitization and at negative and

AMPA Receptor-Mediated Ca2+ Transients in Mouse Olfactory Ensheathing Cells

Frontiers in Cellular Neuroscience, 2019
Ca2+ signaling in glial cells is primarily triggered by metabotropic pathways and the subsequent Ca2+ release from internal Ca2+ stores. However, there is upcoming evidence that various ion channels might also initiate Ca2+ rises in glial cells by Ca2 ...
