Two Signaling Modes Are Better than One: Flux-Independent Signaling by Ionotropic Glutamate Receptors Is Coming of Age

open access: yesBiomedicines
Glutamate is the major excitatory neurotransmitter in the central nervous system. Glutamatergic transmission can be mediated by ionotropic glutamate receptors (iGluRs), which mediate rapid synaptic depolarization that can be associated with Ca2+ entry ...

Evidence for glutamate-mediated excitotoxic mechanisms during photoreceptor degeneration in the rd1 mouse retina [PDF]

open access: yes, 2005
PURPOSE: Kinetic studies of photoreceptor cell death in the retinal degeneration (rd1) mouse model suggest that photoreceptor degeneration could result from cumulative damage.

PSMD14 Stabilizes SLC7A11 to Ameliorate Glucocorticoid‐Induced Osteoporosis by Suppressing Osteocyte Ferroptosis

open access: yesAdvanced Science, EarlyView.
Glucocorticoid‐induced osteoporosis (GIOP) triggers osteocyte ferroptosis via SLC7A11 degradation. PSMD14 stabilizes SLC7A11 by counteracting glucocorticoid‐driven ubiquitination, preserving cystine uptake and glutathione synthesis. AAV‐mediated PSMD14 delivery or its agonist Pantethine rescues osteocyte survival and bone loss in GIOP mice.

Piezoelectric Biomaterials for Bone Regeneration: Roadmap from Dipole to Osteogenesis

open access: yesAdvanced Science, EarlyView.
Piezoelectric biomaterials convert mechanical forces into electrical signals, offering novel strategies to restore and modulate bone microenvironments for tissue engineering. This review examines molecular dipole origins, spatial arrangements, and pseudo‐piezoelectric mechanisms and highlights dipole‐engineering techniques for osteogenesis regulation ...

Natural Allelic Variations in IbCHYR1–IbZnFR Complex Regulate Fusarium Root Rot Resistance in Sweet Potato

open access: yesAdvanced Science, EarlyView.
FfRlpA2, a conserved Fusarium effector, functions as a protease inhibitor by hijacking the E3 ubiquitin ligase IbCHYR1 to degrade the resistance factor IbZnFR, thereby promoting Fusarium pathogenicity. Conversely, the high dosage Pro::IbZnFRHap2 allele was associated with resistance to root rot disease.

Mesenchymal Stromal Cell Secretome and Its Key Bioactive Metabolites Induce Long‐Term Neuroprotection After Traumatic Brain Injury in Mice

open access: yesAdvanced Science, EarlyView.
Pischiutta F and coworkers identify prostaglandins and kynurenine as key mediators of the mesenchymal stromal cells‐derived secretome's neuroprotective effects. A synthetic cocktail composed of these factors promotes long‐term functional recovery, reduces brain structural damage, and modulates neuroinflammation after traumatic brain injury, supporting ...

A High‐Fidelity RNA‐Targeting Cas13X Downregulates Connexin43 in Macroglia: A Novel Neuroprotective Strategy for Glaucoma

open access: yesAdvanced Science, EarlyView.
This study highlights the role of connexin43 (Cx43) in mediating glia activation and neuroinflammation in glaucoma. Using Cx43 knockout mice, it is shown that macroglial cells‐derived Cx43 modulates microglial activation, proliferation, migration, and polarization.

Glutamate receptor expression and chronic glutamate toxicity in rat motor cortex

open access: yesNeurobiology of Disease, 2007
In addition to the loss of spinal motor neurons, amyotrophic lateral sclerosis (ALS) is also associated with degeneration of corticospinal layer V pyramidal neurons and decreased glutamate transport in the cortex. We characterized the glutamate receptors

NIR Driven Pd/Cerium Oxide Nano‐Heterojunction for Enhanced Salvaging Sepsis Induced Acute Liver Injury via Reprogramming Redox Homeostasis in Synergy with Inducing Autophagy

open access: yesAdvanced Science, EarlyView.
In vivo SALI therapy is achieved by scavenging intracellular ROS levels, downregulating inflammatory factors expression levels, inducing macrophage M2 directional polarization, and activating Keap1/Nrf‐2/HO‐1 pathway to reprogram redox homeostasis, induce cellular autophagy, reduce systemic inflammation, and promote liver tissue repair. Abstract Sepsis
