Targeting the PDK1/c‐Myc/SOX10 Signaling in Oligodendrocytes Alleviates Neuropathic Pain

Advanced Science, EarlyView.
This work reveals that oligodendrocyte homeostasis, mediated by PDK1, is a critical determinant of neuropathic pain (NPP) pathogenesis. Disruption of PDK1 in oligodendrocytes impairs SOX10‐dependent myelination programs through c‐Myc accumulation, leading to disrupted myelination and the pathophysiology of NPP.

Multiple functional neurosteroid binding sites on GABAA receptors [PDF]

, 2019
Neurosteroids are endogenous modulators of neuronal excitability and nervous system development and are being developed as anesthetic agents and treatments for psychiatric diseases.

Diminished Signal‐to‐Noise Ratio Disrupts Somatosensory Population Encoding and Drives Tactile Hyposensitivity in the Fmr1−/y Autism Model

Advanced Science, EarlyView.
This study provides a translational approach for linking neural activity to tactile deficits in autism. By combining psychophysics with cortical recordings in a mouse model of autism, we show that low signal‐to‐noise ratio in somatosensory neurons weakens population encoding of fine touch, impairing detection, decoding, and leading to perceptual ...

Analysis of Receptor’s Distribution in Entorhinal Cortex after Induction of Spreading Depression in Juvenile Rats [PDF]

, 2015
Spreading depression (SD), discovered by Leao in 1944, is a pathophysiological wave which propagates slowly in the brain (3 mm/min) and cause dramatic ionic and hemodynamic changes.

Nigra‐Subthalamic Dopaminergic Circuitry Modulates and Represents Distinct Pain Modality in Physiological and Pain States in Mice

Advanced Science, EarlyView.
Nigral dopaminergic (DA) neurons modulate and represent pain with a preference to a particular modality (mechanical) and laterality (contralateral), which are controlled by nigral GABAergic neurons. The pain modulation is mimicked by the nigro‐subthalamic projection and its downstream neurons, involving D2‐like receptors.

Synchrotron XRF Imaging Reveals Manganese Accumulation in the Golgi and Post‐Synapses of Neurons and Enhanced Uptake in Astrocytes

Advanced Science, EarlyView.
Despite widespread exposure, the mechanisms of manganese neurotoxicity remain poorly understood. Using correlative cryogenic fluorescence and synchrotron X‐ray fluorescence imaging techniques, we show that the Golgi apparatus is the primary accumulation site for manganese in both neurons and astrocytes, and that manganese targets the neuronal ...

Membranes and Synaptosomes Used to Investigate Synaptic GABAergic Currents in Epileptic Patients

Membranes
Among the most prevalent neurological disorders, epilepsy affects about 1% of the population worldwide. We previously found, using human epileptic tissues, that GABAergic neurotransmission impairment is a key mechanism that drives the pathological ...

Interaction of GABA and Excitatory Amino Acids in the Basolateral Amygdala: Role in Cardiovascular Regulation [PDF]

, 1997
Activation of the amygdala in rats produces cardiovascular changes that include increases in heart rate and arterial pressure as well as behavioral changes characteristic of emotional arousal.

PVNCRF Neurons Regulate Migraine‐Like Allodynia by Activating CRFR2 on Spinal Trigeminal Caudalis Glutamatergic Neurons

Advanced Science, EarlyView.
Paraventricular CRF neurons in the hypothalamus project to glutamatergic neurons of the spinal trigeminal caudal nucleus, enhancing neuronal activation and CRFR2 signaling. This pathway increases CRF release and excitatory drive, promoting central sensitization and migraine‐related behaviors. Targeting the PVN–SP5C circuit provides a potential strategy

Molecular and pharmacological characterization of native cortical γ- aminobutyric acids receptors containing both α1 and α3 subunits [PDF]

, 1996
We have investigated the existence, molecular composition, and benzodiazepine binding properties of native cortical α1-α3 γ- aminobutyric acid(A) (GABA(A)) receptors using subunit-specific antibodies. The co-existence of α1 and α3 subunits in native GABA(
