Adult-onset leukoencephalopathy with axonal spheroids and pigmented glia (ALSP) is a subtype of dominantly inherited leukoencephalopathies caused by novel CSF1R gene mutation predominantly affecting the cerebral white matter. High signal lesions on diffusion weighted image (DWI) are characteristic. Herein, we describe a patent with ALSP with a novel mutation. The patient had persistent DWI lesions, worsening white matter changes associated with rapidly progressive clinical symptoms.

NG2-glia are a major type of glial cells that are widely distributed in the central nervous system (CNS). Under physiological conditions, they mainly differentiate into oligodendrocytes and contribute to the myelination of axons, so they are generally called oligodendrocyte progenitor cells. Emerging evidence suggests that NG2-glia not only act as the precursors of oligodendrocytes but also possess many other biological properties and functions. For example, NG2-glia can form synapse with neurons and participate in energy metabolism and immune regulation. Under pathological conditions, NG2-glia can also differentiate into astrocytes, Schwann cells and even neurons, which are involved in CNS injury and repair. Therefore, a deeper understanding of the biological characteristics and functions of NG2-glia under physiological and pathological conditions will be helpful for the treatment of CNS injury and disease. This article reviews the recent advances in the biological characteristics and functions of NG2-glia.

Gliosarcoma is a rare primary brain tumor composed of neoplastic glial cells and a sareomatous spindle-cell element. We report three cases of gliosarcoma, and describe their MR findings, which in many respects are very similar to those of malignant astrocytomas. Gliosarcomas are, however, more peripherally located, abutting and/or invading the dura mater, and at T2-weighted imaging their signal intensity is lower than is usually the case with malignant astrocyomas. Despite its rarity, the possibility of gliosarcoma should be considered when MR findings of this nature are apparent.

8.Unlocking the Neurogenic Potential of Mammalian Müller Glia.
International Journal of Stem Cells 2016;9(2):169-175
Müller glia (MG) are the primary support cells in the vertebrate retina, regulating homeostasis in one of the most metabolically active tissues. In lower vertebrates such as fish, they respond to injury by proliferating and reprogramming to regenerate retinal neurons. In mammals, MG may also react to injury by proliferating, but they fail to initiate regeneration. The barriers to regeneration could be intrinsic to mammalian MG or the function of the niche that cannot support the MG reprogramming required for lineage conversion or both. Understanding these mechanisms in light of those being discovered in fish may lead to the formulation of strategies to unlock the neurogenic potential of MG and restore regeneration in the mammalian retina.

Hypoxia has been shown to promote inflammation, including the release of proinflammatory cytokines, but it is poorly investigated how hypoxia directly affects inflammasome signaling pathways. To explore whether hypoxic stress modulates inflammasome activity, we examined the effect of cobalt chloride (CoCl2)-induced hypoxia on caspase-1 activation in primary mixed glial cultures of the neonatal mouse brain. Unexpectedly, hypoxia induced by oxygen-glucose deprivation or CoCl2 treatment failed to activate caspase-1 in microglial BV-2 cells and primary mixed glial cultures. Of particular interest, CoCl2-induced hypoxic condition considerably inhibited NLRP3-dependent caspase-1 activation in mixed glial cells, but not in bone marrow-derived macrophages. CoCl2-mediated inhibition of NLRP3 inflammasome activity was also observed in the isolated brain microglial cells, but CoCl2 did not affect poly dA:dT-triggered AIM2 inflammasome activity in mixed glial cells. Our results collectively demonstrate that CoCl2-induced hypoxia may negatively regulate NLRP3 inflammasome signaling in brain glial cells, but its physiological significance remains to be determined.

Intrathoracic teratoma is mainly found on the anterior mediastinum. For teratoma of the pleura, one case was described. We have presented what we believe to be the first report of a teraroma of the pleura, which was mainly composed of neuroglial cells and was accompanied with lymph node metastasis.
