Summary: The study investigated changes in plasma glial fibrillary acidic protein concentration during sevoflurane anesthesia induction in children under 3 years old and found that three hours of anesthesia did not cause neuronal injury. However, co-administration of dexmedetomidine led to an increase in plasma glial fibrillary acidic protein levels after 180 minutes, indicating a potential effect on neuronal injury that requires further study.

Summary: This study analyzed 35 cases of autoimmune GFAP-A in children, finding diverse clinical manifestations including fever, headache, and convulsions. In addition to common autoimmune syndromes, unique cases were also identified. Most children had a favorable prognosis, and antibody titer was not significantly associated with disease severity.

Summary: This study retrospectively analyzed the clinical features of 11 pediatric patients with autoimmune GFAP astrocytopathy. The results showed that all patients presented with encephalitis and meningoencephalitis, accompanied by symptoms such as fever and headache for most patients. Cerebrospinal fluid analysis revealed elevated white blood cell counts, lactic dehydrogenase levels, protein levels, and slightly reduced glucose levels. Imaging findings showed abnormalities in the brain and spinal cord.

Summary: This study confirms the value of serum GFAP and NfL in PPMS and SPMS, and indicates that the combination of high GFAP and low NfL levels can help identify progression risk in people with progressive multiple sclerosis.

Summary: This study compared neurofilament light chain and GFAP levels in patients with metachromatic leukodystrophy and healthy controls, suggesting that these two proteins may serve as biomarkers for clinical assessment and treatment decisions.

Summary: In autoimmune GFAP astrocytopathy (GFAP-A), there is a predominance of CD8(+) T cells with marked lymphocytic infiltration, especially adjacent to dystrophic neurons and astrocytes. Additionally, there is diffuse infiltration by CD68(+) and CD163(+) macrophages. CD8(+) astrocytes were identified in some samples, but no CD4(+) astrocytes were observed.

Summary: This study aimed to summarize the clinical features of Autoimmune Glial Fibrillary Acidic Protein Astrocytosis mimicking tuberculosis meningitis. The clinical manifestations, cerebrospinal fluid results, and imaging data of five patients were retrospectively analyzed. Anti-GFAP antibody testing should be routinely performed in patients with suspected tuberculosis meningitis to avoid misdiagnosis.

Summary: Autoimmune glial fibrillary acidic protein (GFAP) astrocytopathy is a steroid-responsive autoimmune disease of the nervous system, and timely accurate diagnosis and appropriate treatment are crucial for improving patient outcomes.

Summary: Autoimmune GFAP astrocytopathy is a novel form of autoimmune meningoencephalitis related to GFAP autoantibodies, with few pediatric cases reported. Diagnosis is confirmed through MRI analysis and antibody testing, with treatment usually involving IVIG and intravenous steroids.

Summary: GFAP is found to be overexpressed and differentially phosphorylated in Alzheimer's disease, especially in patients with specific genotype. Knockdown of kinases involved in GFAP phosphorylation can reduce amyloid accumulation and associated behavioral traits. A small molecule compound, MSR1, has been identified to bind specifically to GFAP and may have therapeutic potential in treating AD.

Summary: This study found that serum GFAP/NfL levels in patients with unipolar depression were lower compared to healthy controls, while NfL levels increased during the follow-up period. Although no consistent associations were found between GFAP/NfL and depression severity or cognitive function, the study may support the presence of glial dysfunction but limited neuron damage in depression.

Summary: Serum GFAP exhibits relatively low within-subject variation but considerable between-subject variation, and shows marked semidiurnal variation. Therefore, caution should be exercised in blood sampling and interpreting GFAP, especially in conditions where only small GFAP differences are observed.

Summary: This study aimed to investigate the role of blood GFAP in evaluating the clinical severity of HD. The concentrations of plasma NfL and GFAP were analyzed and compared with clinical severity assessments, suggesting that GFAP may be a sensitive biomarker for evaluating HD progression.

Summary: In patients with metastatic breast cancer, elevated serum levels of GFAP are independently associated with the presence of brain metastases and poor outcomes, outperforming other biomarkers such as NfL, UCHL1, and tau. These findings suggest that GFAP may serve as a valuable diagnostic and prognostic factor for brain metastases in this patient population, although further validation in independent cohorts is necessary.
