Epilepsy is a brain condition characterized by the recurrence of unprovoked seizures. Recent studies have shown that complement component 3 (C3) aggravate the neuronal injury in epilepsy. And our previous studies revealed that TRPV1 (transient receptor potential vanilloid type 1) is involved in epilepsy. Whether complement C3 regulation of neuronal injury is related to the activation of TRPV1 during epilepsy is not fully understood. We found that in a mouse model of status epilepticus (SE), complement C3 derived from astrocytes was increased and aggravated neuronal injury, and that TRPV1-knockout rescued neurons from the injury induced by complement C3. Circular RNAs are abundant in the brain, and the reduction of circRad52 caused by complement C3 promoted the expression of TRPV1 and exacerbated neuronal injury. Mechanistically, disorders of neuron-glia interaction mediated by the C3-TRPV1 signaling pathway may be important for the induction of neuronal injury. This study provides support for the hypothesis that the C3-TRPV1 pathway is involved in the prevention and treatment of neuronal injury and cognitive disorders.

Ischemic stroke (IS) has high morbidity/mortality with limited treatments. This study screened core copper homeostasis-related genes in IS and validated their function as precise intervention targets. Human IS gene chip data were retrieved from GEO, and copper homeostasis genes from multiple databases.

Objective: To investigate the correlation between postoperative serum glial fibrillary acidic protein (GFAP) and 3-nitrotyrosine (3-NT) levels and neuronal injury severity in glioma patients.
Methods: 150 glioma patients were enrolled, with clinical baseline and pathological data recorded (age, sex, etc.).

Introduction/aims: Therapeutic electrical stimulation (ES) of repaired nerves has been demonstrated to improve muscle function. Previous studies applied ES to the proximal transected nerve end (P-ES) with benefits to the neuronal cell body. We investigated whether a single ES dose applied to the distal end (D-ES) or distal and proximal ends (DP-ES) prior to nerve repair provides benefits to neuromuscular junction (NMJ) and muscle recovery.

Microglia, the central nervous system's resident macrophages, are critical for immune defense, protecting neurons during infection. Their role in postnatal brain development, particularly after injury, remains unclear. Nucling, a protein up-regulated during cardiac muscle differentiation, regulates NF-κB, influencing apoptosis and cell proliferation.

Primary microcephaly, a rare congenital condition characterized by reduced brain size, occurs due to impaired neurogenesis during brain development. Through whole-exome sequencing, we identified compound heterozygous loss-of-function mutations in CENTRIN 3 (CETN3) in a 5-year-old patient with primary microcephaly. As CETN3 has not been previously linked to microcephaly, we investigated its potential function in neurodevelopment in human pluripotent stem cell-derived cerebral organoids.
