The administration of pan histone deacetylase (HDAC) inhibitors reduces ischemic damage to the CNS, both in vitro and in animal models of stroke, via mechanisms which we are beginning to understand. The acetylation of p53 is regulated by Class I HDACs and, because p53 appears to play a role in ischemic pathology, the purpose of this study was to discover,(More)
Hereditary spastic paraplegia (HSP) is a neurological syndrome characterized by degeneration of central nervous system (CNS) axons. Mutated HSP proteins include myelin proteolipid protein (PLP) and axon-enriched proteins involved in mitochondrial function, smooth endoplasmic reticulum (SER) structure, and microtubule (MT) stability/function. We(More)
UNLABELLED The impact of aging on CNS white matter (WM) is of general interest because the global effects of aging on myelinated nerve fibers are more complex and profound than those in cortical gray matter. It is important to distinguish between axonal changes created by normal aging and those caused by neurodegenerative diseases, including multiple(More)
BACE1 is an indispensable enzyme for generating β-amyloid peptides, which are excessively accumulated in brains of Alzheimer's patients. However, BACE1 is also required for proper myelination of peripheral nerves, as BACE1-null mice display hypomyelination. To determine the precise effects of BACE1 on myelination, here we have uncovered a role of BACE1 in(More)
Amyloid precursor protein, which generates amyloid beta peptides, is intimately associated with Alzheimer's disease (AD) pathogenesis. We previously showed that transgenic mice overexpressing amyloid precursor protein intracellular domain (AICD), a peptide generated simultaneously with amyloid beta, develop AD-like pathologies, including hyperphosphorylated(More)
Although synaptically released, vesicular Zn(2+) has been proposed to play a neuromodulatory or neuronal signaling role at the mossy fiber-CA3 synapse, Zn(2+) release remains controversial, especially when detected using fluorescent imaging. In the present study, we investigated synaptically released Zn(2+) at the mossy fiber (MF) synapse in rat hippocampal(More)
