Transient Sleep Deprivation Induces Persistent Auditory Neuropathy via ROS‐Initiated Neuroinflammation and BK Channel Suppression

Advanced Science, EarlyView.
Sleep disturbance severity closely tracks hearing loss in a clinical cohort, yet the mechanistic link remains unclear. Acute sleep deprivation is shown to trigger transient cochlear oxidative stress that switches into a self‐sustaining neuroinflammatory state, suppressing BK channels and causing irreversible synaptopathy.

Palmitoyl Acyltransferase Zdhhc17 Promotes Functional Recovery After Spinal Cord Injury by Targeting the Nuclear Transport Factors Kpna2 and Ipo9

Advanced Science, EarlyView.
In this study, we demonstrate that Zdhhc17, acting as a PAT, suppresses neuronal apoptosis and promotes axon regeneration after injury, thereby enhancing functional recovery following SCI. In this context, Kpna2 and Ipo9 serve as novel palmitoylation substrates of Zdhhc17, whose palmitoylation prevents the injury‐induced degradation of their proteins ...

Retrograde transport of neurotrophin receptor TrkB-FL induced by excitotoxicity regulates Golgi stability and is a target for stroke neuroprotection

Cell Death and Disease
Excitotoxicity, aberrant function of survival pathways dependent on brain-derived neurotrophic factor (BDNF), and disruption of the Golgi complex are shared pathological hallmarks in relevant neurological diseases, including stroke.

Shared Metabolic–Proteinopathy Axis in Alzheimer's Disease and Parkinson's Disease: Evidence for a Convergent but Not Identical Disease Spectrum

AGING MEDICINE, EarlyView.
This review explores the common pathological mechanisms underlying Alzheimer's disease (AD) and Parkinson's disease (PD), with an emphasis on glucose metabolism and insulin resistance. We examine how disruptions in glucose metabolism and insulin resistance influence the onset and advancement of both Alzheimer's disease (AD) and Parkinson's disease (PD).

The liver‐brain axis: A multidimensional regulatory network implicated in Alzheimer's disease pathogenesis and clinical implications

Animal Models and Experimental Medicine, EarlyView.
Schematic diagram of the core pathways of the liver‐brain axis in regulating AD. The liver regulates cerebral Aβ deposition, tau phosphorylation, and neuroinflammation through pathways such as metabolic detoxification (urea cycle, ketone body metabolism, glutathione antioxidant system), molecular secretion (APOE, CRP, FGF21, IGF‐1), and Aβ clearance ...

Excitotoxicity and stroke: Identifying novel targets for neuroprotection [PDF]

, 2014
Excitotoxicity, the specific type of neurotoxicity mediated by glutamate, may be the missing link between ischemia and neuronal death, and intervening the mechanistic steps that lead to excitotoxicity can prevent stroke damage. Interest in excitotoxicity

The Role of Neuronal Pentraxin 2 (NP2) in Regulating Glutamatergic Signaling and Neuropathology

Frontiers in Cellular Neuroscience, 2020
Pentraxins are a superfamily of evolutionarily conserved proteins that are characterized by their multimeric architecture and their calcium-dependent binding.

Neuroprotection after transient middle cerebral artery occlusion in male rats using kojic acid nanostructured lipid carriers: A behavioral, biochemical, and histological study on hippocampal CA1 region

Animal Models and Experimental Medicine, EarlyView.
This study demonstrates that kojic acid–loaded nanostructured lipid carriers (KA‐NLC) provide significant neuroprotection in a male rat model of middle cerebral artery occlusion (MCAO)–induced stroke. Treatment with KA‐NLCs reduced cerebral edema, improved motor and coordination balance and neurological scores, and enhanced spatial and avoidance memory.
