Report of Resistant Varicella Zoster Infection Treated With Donor Lymphocyte Infusion in a Pediatric Oncology Patient

We report an 8-year-old boy with disseminated, life-threatening, drug treatment-resistant varicella zoster infection occurring during standard treatment for neuroblastoma in whom viral clearance and cure was effected by donor Lymphocyte infusion from his HLA (Human leukocyte antigen)-identical twin sibling.

This study investigates whether METH induces autophagy in the human dopaminergic neuroblastoma cell line SH-SY5Y, then examines the neuroprotective effects of gastrodin against autophagy in METH-treated SH-SY5Y cells. The effects of METH on the protein expressions of autophagy-related genes (LC3B and Beclin-1) were evaluated with and without gastrodin. The presence of autophagosomes in the METH-induced treatment with and without gastrodin is revealed through transmission electron microscopy. Pharmacological intervention was employed to study the role of the AKT/mTOR signaling pathway in the gastrodin-mediated neuroprotecti...

Authors: Nieddu V, Piredda R, Bexell D, Barton J, Anderson J, Sebire N, Kolluri K, Janes SM, Karteris E, Sala A Abstract Drug-resistant neuroblastoma remains a major challenge in paediatric oncology and novel and less toxic therapeutic approaches are urgently needed to improve survival and reduce the side effects of traditional therapeutic interventions. Mesenchymal stem cells (MSCs) are an attractive candidate for cell and gene therapy since they are recruited by and able to infiltrate tumours. This feature has been exploited by creating genetically modified MSCs that are able to combat cancer by delivering therap...

In this study, we analyzed the expression level and role of miRNA-186-5p and Eg5 in neuroblastoma and neuroblastoma cell lines SHSY-5Y, Kelly, NBL-S and SK-N-AS. Results of Real-time PCR and immunohistochemistry showed that the expression level of Eg5 in tumor tissues was higher than that in tumor adjacent tissues, while miRNA-186-5p expression level in tumor tissues was lower than that in tumor adjacent tissues. miRNA-186-5p mimics or Eg5 siRNA was transfected into SHSY-5Y and Kelly cells, CCK-8 and soft agar clone formation tests' results showed that the cell proliferation was inhibited. Flow cytometry analysis of cell a...

In this study, we have examined the molecular mechanism of the toxicity of acetylated K274-tau. We incorporated an acetylation mimicking mutation at K274 (K->Q) residue of tau. The mutation (K274Q) strongly reduced the ability of tau to bind to tubulin and also to polymerize tubulin while K274R mutation did not reduce the ability of tau either to bind or polymerize tubulin. In addition, K274Q-tau displayed a higher aggregation propensity than wild-type tau as evident from thioflavin S fluorescence, tryptophan fluorescence, and electron microscopic images. Furthermore, dynamic light scattering, atomic force microscopy, a...

CONCLUSION: Gluconeogenesis was induced in human neural cells exposed to fine particles (DEP), in association with cell damage and oxidative stress. These findings suggest that the pathogenesis of cerebrovascular injury due to fine particle pollutant exposure may proceed through derangements in gluconeogenic metabolism. ABBREVIATIONS: DEP: diesel exhaust particles, ICA: intracranial atherosclerosis, ROS: reactive oxygen species. PMID: 31099309 [PubMed - as supplied by publisher]

cke F Abstract Cu isotope fractionation was investigated in the human neuroblastoma SH-SY5Y cell line, in a proliferating/tumor phase (undifferentiated cells), and in a differentiated state (neuron-like cells), induced using retinoic acid (RA). The SH-SY5Y cell line displays genetic aberrations due to its cancerous origin, but differentiation drives the cell line towards phenotypes suitable for the research of neurological diseases (e.g., Alzheimer's disease or Parkinson's disease). Cellular Cu distribution was first explored by laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) imaging and, s...

In this study, we further evaluated if exposure to honokiol for short periods could induce autophagy and subsequent apoptosis of neuroblastoma cells and possible mechanisms. Exposure of neuroblastoma neuro-2a cells to honokiol for 24 h induced morphological shrinkage and cell death. As to the mechanisms, honokiol consecutively induced cytochrome c release from mitochondria, caspase-3 activation, DNA fragmentation and cell apoptosis. Separately, honokiol time-dependently augmented the proportion of autophagic cells and the ratio of light chain 3 (LC3)-II/LC3-I. Pretreatment of neuro-2a cells with 3-methyladenine, an inhibit...

A 22-month-old boy diagnosed with neuroblastoma was evaluated by bone scintigraphy and 123I-metaiodobenzylguanidine scintigraphy, and no metastases to skeletal system was detected. However, plain radiograph and MRI revealed suspected metastatic lesions. The patient was therefore evaluated by 68Ga-DOTA-TATE PET/CT, and 68Ga-DOTA-TATE uptake was observed in multiple bone and bone marrow areas, which were consistent with metastases. Biopsy was taken from the right iliac bone, and the pathological examination of the biopsy specimen was coherent with neuroblastoma invasion.
