Snake and spider toxins induce a rapid recovery of function of botulinum neurotoxin paralysed neuromuscular junction [PDF]

open access: yes, 2015
Botulinum neurotoxins (BoNTs) and some animal neurotoxins (-Bungarotoxin, -Btx, from elapid snakes and -Latrotoxin, -Ltx, from black widow spiders) are pre-synaptic neurotoxins that paralyse motor axon terminals with similar clinical outcomes in patients.

Mammalian Tolerance to Amino Acid Heterochirality

open access: yesChemBioChem, Accepted Article.
Organisms use amino acids predominantly in l‐configuration. On the other hand, a series of studies show that a variety of d‐amino acids also occur in mammals and amino acid homochirality is not complete. Mammals de novo synthesize most amino acids with l‐configuration, but serine and aspartate are converted from l‐ to d‐configuration by endogenous ...

A postsynaptic PI3K-cII dependent signaling controller for presynaptic homeostatic plasticity

open access: yeseLife, 2018
Presynaptic homeostatic plasticity stabilizes information transfer at synaptic connections in organisms ranging from insect to human. By analogy with principles of engineering and control theory, the molecular implementation of PHP is thought to require ...

Computational Astrocyence: Astrocytes encode inhibitory activity into the frequency and spatial extent of their calcium elevations [PDF]

open access: yesarXiv, 2019
Deciphering the complex interactions between neurotransmission and astrocytic $Ca^{2+}$ elevations is a target promising a comprehensive understanding of brain function. While the astrocytic response to excitatory synaptic activity has been extensively studied, how inhibitory activity results to intracellular $Ca^{2+}$ waves remains elusive.

Normal spatial learning and improved spatial working memory in mice (mus musculus) lacking dopamine d4 receptors [PDF]

open access: yes, 2001
Dopamine terminals in the hippocampus and prefrontal cortex modulate cognitive processes such as spatial learning and working memory. Because dopamine D4 receptors are expressed in these brain areas we have analyzed mutant mice lacking this receptor ...

Novel 4,5‐Dihydrothiazole‐phenylpiperazine Derivatives: Synthesis, Docking Studies and Pharmacological Evaluation as Serotonergic Agents

open access: yesChemMedChem, Accepted Article.
We have described the synthesis of a new series of LCAPs (long‐chain arylpiperazine) as serotoninergic ligands (FG 1‐18). The combination of structural elements including heterocyclic nucleus, propyl chain and 4,5‐dihydrothiazol‐2‐ylphenylpiperazines, led to the preparation of different derivatives tested for their affinity toward 5‐HT1A, 5‐HT2A and 5 ...

Imaging neuropeptide release at synapses with a genetically engineered reporter

open access: yeseLife, 2019
Research on neuropeptide function has advanced rapidly, yet there is still no spatio-temporally resolved method to measure the release of neuropeptides in vivo.

Astrocytic GABA transporter activity modulates excitatory neurotransmission

open access: yesNature Communications, 2016
Astrocytes are ideally placed to detect and respond to network activity. They express ionotropic and metabotropic receptors, and can release gliotransmitters.

Identification of a Core Amino Acid Motif within the α Subunit of GABAARs that Promotes Inhibitory Synaptogenesis and Resilience to Seizures [PDF]

open access: yes, 2019
The fidelity of inhibitory neurotransmission is dependent on the accumulation of γ-aminobutyric acid type A receptors (GABAARs) at the appropriate synaptic sites.
