The cerebellum is one of the well-known targets of the pathological processes underlying spinocerebellar ataxia type 2 (SCA2) and type 3 (SCA3). Despite its pivotal role for the clinical pictures of these polyglutamine ataxias, no pathoanatomical studies of serial tissue sections through the cerebellum have been performed in SCA2 and SCA3 so far. Detailed(More)
AIMS HSPB8 is a small heat shock protein that forms a complex with the co-chaperone BAG3. Overexpression of the HSPB8-BAG3 complex in cells stimulates autophagy and facilitates the clearance of mutated aggregation-prone proteins, whose accumulation is a hallmark of many neurodegenerative disorders. HSPB8-BAG3 could thus play a protective role in protein(More)
The human brainstem is involved in the regulation of the sleep/waking cycle and normal sleep architectonics and is crucial for the performance of a variety of somatomotor, vital autonomic, oculomotor, vestibular, auditory, ingestive and somatosensory functions. It harbors the origins of the ascending dopaminergic, cholinergic, noradrenergic, serotonergic(More)
Childhood meningiomas are rare. Recently, a new hereditary tumor predisposition syndrome has been discovered, resulting in an increased risk for spinal and intracranial clear cell meningiomas (CCMs) in young patients. Heterozygous loss-of-function germline mutations in the SMARCE1 gene are causative, giving rise to an autosomal dominant inheritance pattern.(More)
Spinocerebellar ataxia type 23 is caused by mutations in PDYN, which encodes the opioid neuropeptide precursor protein, prodynorphin. Prodynorphin is processed into the opioid peptides, a-neoendorphin, and dynorphins A and B, that normally exhibit opioid-receptor mediated actions in pain signalling and addiction. Dynorphin A is likely a mutational hotspot(More)
In an increasing number of central nervous system (CNS) diseases a pathogenic contribution of the immune system is proposed. However, the exact underlying mechanisms are often poorly understood. The collection of articles in this special issue presents a state-of-the-art review of adaptive and innate immune mechanisms and their main players in number CNS(More)
Most cells of the developing mammalian brain derive from the ventricular (VZ) and the subventricular (SVZ) zones. The VZ is formed by the multipotent radial glia/neural stem cells (NSCs) while the SVZ harbors the rapidly proliferative neural precursor cells (NPCs). Evidence from human and animal models indicates that the common history of hydrocephalus and(More)
Sensory abnormalities in Complex Regional Pain Syndrome type 1 (CRPS 1) have been associated with changes in dorsal horn N-Methyl-D-Aspartate (NMDA) receptor activity resulting in central sensitization. However, little is known about changes in NMDA receptor expression in peripheral tissue for this syndrome. The goal of the present study was to evaluate(More)
