Anterior cingulate cortex and insomnia: A cingulate-striatum connection
CellPress | Neuron Journal
by Qi-Yu Chen, Min Zhuo
1d ago
Insomnia is an important comorbidity of chronic pain. In this issue of Neuron, Li et al. report that chronic-pain-induced insomnia is mediated by the pyramidal neurons in the anterior cingulate cortex and their dopaminergic projections to the dorsal medial striatum ..read more

PHeeling the pHorce
CellPress | Neuron Journal
by Sang-Min Jeon, Michael J. Caterina
1d ago
In this issue of Neuron, Yamada et al.1 show that fast excitatory neurotransmission by protons acting at acid-sensing ion channels (ASICs) mediates mechanical force-evoked signaling at the Merkel cell-neurite complex (MNC), contributing to mammalian tactile discrimination ..read more

14-3-3θ, a novel player in TDP-43 pathophysiology: Implications for ALS/FTD
CellPress | Neuron Journal
by Bilal Khalil, Sandrine Da Cruz
1d ago
In this issue of Neuron, Ke et al. report a novel non-canonical interaction between 14-3-3θ and TDP-43 that impacts loss-of-function and gain-of-toxic pathology in TDP-43 proteinopathies. The authors further provide proof of principle for a 14-3-3θ-targeted gene therapy to reduce TDP-43-induced deficits in transgenic TDP-43 mutant mice ..read more

Interferons: Invited guests at the brain’s gala banquet
CellPress | Neuron Journal
by Mar Márquez-Ropero, Amanda Sierra
1d ago
Removal of toxic debris that can hinder brain function is performed primarily by microglia, the brain’s professional phagocytes. A recent study in Cell1 identified that viral response interferons are required for priming microglia, ensuring competent phagocytosis and proper circuit wiring ..read more

Cross-hemispheric communication: Insights on lateralized brain functions
CellPress | Neuron Journal
by Sebastian Ocklenburg, Zengcai V. Guo
1d ago
Ocklenburg and Guo review the current state of knowledge on cross-hemispheric communication in the vertebrate brain, with a focus on recent research in rodents. They discuss how lateralization in sensory, memory, and motor functions can emerge from asymmetric cross-hemispheric communication ..read more

Multimodal sensory control of motor performance by glycinergic interneurons of the mouse spinal cord deep dorsal horn
CellPress | Neuron Journal
by Mark A. Gradwell, Nofar Ozeri-Engelhard, Jaclyn T. Eisdorfer, Olivier D. Laflamme, Melissa Gonzalez, Aman Upadhyay, Laura Medlock, Tara Shrier, Komal R. Patel, Adin Aoki, Melissa Gandhi, Gloria Abbas-Zadeh, Olisemaka Oputa, Joshua K. Thackray, Matthew Ricci, Arlene George, Nusrath Yusuf, Jessica Keating, Zarghona Imtiaz, Simona A. Alomary, Manon Bohic, Michael Haas, Yurdiana Hernandez, Steven A. Prescott, Turgay Akay, Victoria E. Abraira
1d ago
Gradwell et al. highlight the medial deep dorsal horn as a hub for sensory convergence in the spinal cord. Within this region, they identify a population of glycinergic inhibitory interneurons providing broad ipsilateral inhibition to pre-motor and motor networks to gate cutaneous-evoked muscle activity, ensuring smooth movement transitions ..read more

Mechanisms of sex differences in Alzheimer’s disease
CellPress | Neuron Journal
by Chloe Lopez-Lee, Eileen Ruth S. Torres, Gillian Carling, Li Gan
1d ago
This review by Lopez-Lee and Torres et al. summarizes sex-specific differences in AD and potential biological mechanisms and discusses how sex hormones and chromosomes may influence inflammation, metabolism, and autophagy in aging, contributing to distinct disease patterns in men and women ..read more

Tuned geometries of hippocampal representations meet the computational demands of social memory
CellPress | Neuron Journal
by Lara M. Boyle, Lorenzo Posani, Sarah Irfan, Steven A. Siegelbaum, Stefano Fusi
1d ago
Social memory consists of both familiarity detection and recollection of past social episodes. Whether and how the hippocampus fulfills these roles is unclear. Boyle, Posani, et al. find that the hippocampal CA2 region meets the distinct computational demands of these processes through tuning the geometry of structured neural activity ..read more

Sustained antidepressant effects of ketamine metabolite involve GABAergic inhibition-mediated molecular dynamics in aPVT glutamatergic neurons
CellPress | Neuron Journal
by Ayako Kawatake-Kuno, Haiyan Li, Hiromichi Inaba, Momoka Hikosaka, Erina Ishimori, Takatoshi Ueki, Yury Garkun, Hirofumi Morishita, Shuh Narumiya, Naoya Oishi, Gen Ohtsuki, Toshiya Murai, Shusaku Uchida
1d ago
Kawatake-Kuno, Li, Inaba, et al. considered a midline thalamic structure, the aPVT, a crucial brain region involved in the sustained antidepressant-like effects of the ketamine metabolite (2S,6S)-HNK. Moreover, they uncover the mechanisms whereby this drug drives its antidepressant-like effects via modulation of GABAergic-inhibition-mediated epigenetic regulations in the aPVT ..read more

Targeting 14-3-3θ-mediated TDP-43 pathology in amyotrophic lateral sclerosis and frontotemporal dementia mice
CellPress | Neuron Journal
by Yazi D. Ke, Annika van Hummel, Carol Au, Gabriella Chan, Wei Siang Lee, Julia van der Hoven, Magdalena Przybyla, Yuanyuan Deng, Miheer Sabale, Nicolle Morey, Josefine Bertz, Astrid Feiten, Stefania Ippati, Claire H. Stevens, Shu Yang, Amadeus Gladbach, Nikolas K. Haass, Jillian J. Kril, Ian P. Blair, Fabien Delerue, Lars M. Ittner
1d ago
TDP-43 forms neuronal deposits in amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) due to unknown causes. Ke et al. identified the TDP-43 interactor 14-3-3θ, which promotes TDP-43 deposition. They devised a treatment harnessing 14-3-3θ’s affinity for TDP-43, mitigating deficits and neurodegeneration in ALS/FTD models with implications for future therapy ..read more
