Advanced Science, EarlyView.Contextual cues recruit the glutamatergic vCA1–dmPFC pathway to retrieve morphine reward memory by reshaping cell‐type‐specific prefrontal microcircuit activity. Distinct regulation of PV+ and SST+ interneurons defines this hippocampal–prefrontal mechanism.

An Efficient Synthesis of Tetrodotoxin [PDF]
, 2021 Tetrodotoxin (TTX) is an indispensable probe in neuroscience, a biosynthetic and ecological enigma, and one of the most celebrated targets of synthetic chemistry. Here, we present a stereoselective synthesis of TTX that proceeds in 22 steps starting from

Advanced Science, EarlyView.ABSTRACT Beta‐amyloid peptide (Aβ)‐induced suppression of hippocampal GABAergic interneuron activity drives hyperexcitability, amyloid pathology, and cognitive impairment in Alzheimer's disease (AD), suggesting that enhancing hippocampal inhibition may be protective.

Advanced Science, EarlyView.Neuronal activation leads to astrocytic transient volume changes, activating transient receptor potential ankyrin 1 (TRPA1) channels, leading to Ca2+ influx. Activation of TRPA1 causes the release of D‐serine through BEST1. Finally, the augmented extracellular levels of D‐serine boost neuronal activity by binding GluN1‐containing NMDARs, leading to CBV

The skin microbiome facilitates adaptive tetrodotoxin production in poisonous newts
eLife, 2020 Rough-skinned newts (Taricha granulosa) use tetrodotoxin (TTX) to block voltage-gated sodium (Nav) channels as a chemical defense against predation.

Elucidating the Origin of Tetrodotoxin in Pleurobranchaea maculata and Stylochoplana sp. [PDF]
, 2015 Tetrodotoxin (TTX) is an extremely potent neurotoxin that acts by selectively targeting voltage gated sodium channels blocking propagation of action potentials.

Advanced Science, EarlyView.Administration of opioids activates ephrinB2‐EphB1 receptor signaling. Activated EphB1 receptors induce GRK2‐mediated phosphorylation of MOR at Ser375, which initiates the internalization of MOR and reduces opioid antinociception at the behavioral level. ABSTRACT Opioids are the primary treatment for severe pain in clinical practice.

Marine Drugs, 2022 Multiple animal species have evolved resistance to the neurotoxin tetrodotoxin (TTX) through changes in voltage-gated sodium ion channels (VGSCs). Amino acid substitutions in TTX-resistant lineages appear to be positionally convergent with changes in ...

New insights into epileptic spasm generation and treatment from the TTX animal model
Epilepsia Open, EarlyView.Abstract Currently, we have an incomplete understanding of the mechanisms underlying infantile epileptic spasms syndrome (IESS). However, over the past decade, significant efforts have been made to develop IESS animal models to provide much‐needed mechanistic information for therapy development.
