Cerebellar gangliocytoma can correspond to Lhermitte-Duclos disease, a benign hamartomatous malformation encountered in young adults. It can also be a part of gangliogliomas/gangliocytomas family, which usually encompasses temporal pediatric neoplasms associated with longstanding seizures. We report a case of a young 11-year-old patient who presented with a gangliocytoma of the cerebellum revealed by neurologic manifestations (headache, dyspraxia, equilibrium and gait disturbances). Diagnosis was made on surgical material. Tumour was characterized by dysplastic mature ganglion cells, perivascular lymphocytic infiltrates and no glial neoplastic component. By immunohistochemistry, ganglion cells expressed neurofilaments, MAP2 protein, synaptophysin, chromogranin A and S100 protein. BRAF V600E mutation was absent. Clinical characteristics, radiology, histopathology of the two main diagnoses are discussed.

Systemic TRPV4 inhibition worsens retinal response to acute intraocular pressure elevation in older but not younger mice.
Optom Vis Sci

Department of Anatomy and Physiology, The University of Melbourne, Parkville, Victoria, Australia.
Significance: Previous evidence showed that transient receptor potential vanilloid 4 (TRPV4) inhibition was protective of retinal ganglion cell (RGC) loss after chronic intraocular pressure (IOP) elevation in young animals. However, the role of TRPV4 in mechanosensing IOP changes in the aging eye is not well understood.
Purpose: This study compared the recovery of retinal function and structure after acute IOP elevation in 3- and 12-month-old mouse eyes with and without TRPV4 inhibition.

Introduction: Cisplatin is extensively employed in the treatment of multiple solid malignant tumors. Nevertheless, side effects such as cisplatin-induced ototoxicity (CIO) pose obstacles to tumor therapy.The important natural product chiisanoside from has abundant activity against CIO.

Introduction: Resveratrol, a polyphenolic compound commonly found in natural plants and fruits, exhibits potential in preventing optic nerve damage in glaucoma, as indicated by several animal studies. However, there is presently a dearth of relevant evidence available for comprehensive summarization.
Methods: In this study, we conducted an extensive search across 7 electronic databases, encompassing all pertinent animal studies for a systematic review and meta-analysis.
The visual system of teleost fish grows continuously, which is a useful model for studying regeneration of the central nervous system. Glial cells are key for this process, but their contribution is still not well defined. We followed oligodendrocytes in the visual system of adult zebrafish during regeneration of the optic nerve at 6, 24, and 72 hours post-lesion and at 7 and 14 days post-lesion via the sox10:tagRFP transgenic line and confocal microscopy.

Activation of bone morphogenetic protein (BMP) 4 signaling promotes the survival of retinal ganglion cell (RGC) after acute injury. In this study, we investigated the role of the BMP4 signaling pathway in regulating the degeneration of retinal ganglion cells (RGCs) in a mouse glaucoma model and its potential application in retinal stem cell. Our results demonstrate that BMP4-GPX4 not only reduces oxidative stress and iron accumulation but also promotes neuroprotective factors that support the survival of transplanted RSCs into the host retina.
