Astrocytic Ca2+ Prevents Synaptic Depotentiation by Limiting Repetitive Activity in Dendrites During Motor Learning

Background and Motivation In the field of neuroscience, learning and memory processes rely on the intricate regulation of cellular activities in the brain. Previous research has predominantly focused on synaptic plasticity between neurons—such as long-term potentiation (LTP) and long-term depression (LTD)—as the material basis for the remodeling of...

Inflammasome Signaling in Astrocytes Modulates Hippocampal Plasticity

Academic Background In recent years, the role of immune signaling pathways in nervous system homeostasis has garnered increasing attention. Traditionally, the inflammasome, a core complex of innate immunity, was thought to activate only during infection or tissue damage, participating in pathological processes through caspase-1-mediated pyroptosis ...

Glioma–Astrocyte Connexin43 Confers Temozolomide Resistance Through Activation of the E2F1/ERCC1 Axis

Study on Connexin43-Mediated Temozolomide Resistance in Glioma through Activation of the E2F1/ERCC1 Axis Academic Background Glioma is the most common and fatal tumor of the central nervous system, with temozolomide (TMZ) being the standard treatment. However, TMZ therapy often leads to tumor recurrence and drug resistance, severely limiting its ef...

Astrocyte Ensembles Manipulated with Astrolight Tune Cue-Motivated Behavior

New Discoveries in Astrocyte Regulation of Behavior: Application of the AstroLight Tool Academic Background For a long time, neuroscience research has primarily focused on neuronal activity, while neglecting the role of astrocytes in brain function. Although astrocytes are one of the most numerous cell types in the brain, they have traditionally be...

Hyperglycemia Enhances Brain Susceptibility to Lipopolysaccharide-Induced Neuroinflammation via Astrocyte Reprogramming

Hyperglycemia Enhances Brain Susceptibility to Lipopolysaccharide-Induced Neuroinflammation via Astrocyte Reprogramming Academic Background Introduction Diabetes is a chronic metabolic disease affecting millions of people worldwide, characterized by hyperglycemia, or elevated blood glucose levels. For a long time, research has primarily focused on ...

Neonatal Respiratory Infection Causes Neuroinflammation in the Brainstem

Neonatal Respiratory Infections Lead to Brainstem Neuroinflammation Introduction Respiratory infections are one of the most common diseases and causes of morbidity among newborns. During the acute phase, infections are known to cause widespread peripheral inflammation. However, the effect of this inflammation on the critical neural centers that con...
