BACKGROUND Tumors that arise in the temporal lobes of infants and spread to the neural system are limited to several diagnoses. Herein, we present an infantile case of a temporal tumor showing neuronal and glial differentiation. CASE PRESENTATION The patient was a 9-month-old boy with low body weight due to intrauterine growth retardation. At 9 months after birth, he presented partial seizure...

In many organisms, single neural stem cells can generate both neurons and glia. How are these different cell types produced from a common precursor? In Drosophila, glial cells missing (gcm) is necessary and sufficient to induce glial development in the CNS. gcm mRNA has been reported to be asymmetrically localized to daughter cells during precursor cell division, allowing the daughter cell to p...

Autism spectrum disorder (ASD) is a neurodevelopmental with an increasing frequency, manifested by functional disorders in social communication and interaction, limited interests, repetitive behaviors. The etiology of autism has not yet been fully elucidated there are many areas that need further study. Increasing studies have shown disruptions synaptic functions critical the onset ASD. Glial c...

Background: Opioids are amongst the most common abused drugs. Pathologic studies on opioid abuse are limited since the evaluation of inflammation and regeneration in brain tissue is not as simple as other tissues of the body. Thus, the present study aimed to determine the relationship between the dependence on morphine and inflammatory and regenerative processes. Methods: In this experimental s...

Background: The present study was designed to evaluate the secondary microglial activation processes after spinal cord injury (SCI). Methods: A quantitative histological study was performed to determine ED-1 positive cells, glial cell density, and cavitation size in untreated SCI rats at days 1, 2, and 4, and weeks 1, 2, 3, and 4. Results: The results of glial cell quantification along the 4900...

the toll like (family of receptors tlr) are expressed primarily by immune cells and are known to be part of innate immune system. in the past decade involvement of tlrs in several physiologic and pathologic pathways has been proved. pain transmission via glial activation is one of such interesting fields. both pathological pain states and treatment have also been shown to be related to tlr-rela...

background: in recent years, adipose tissue, due to the stem cells contained within, has found a new special place in laboratory and clinical applications. these adipose‑derived stem cells (adscs) have the same characteristics of bone marrow mesenchymal stem cells (bmscs). although bone marrow (bm) is not easily accessible and its procurements may be painful, most patients possess excess fat wh...

Rosette-forming glioneuronal tumour (RGNT) of the fourth ventricle is a relatively new entity recently described. Neuronal and mixed neuronal-glial tumours have been incorporated in the same category in the WHO Classification of Nervous System Tumours. This category comprises heterogeneous neoplasms composed of neuronal and glial cells with various grades of differentiation. We present a case o...
