In the history of medicine, one means to progress is when we make the decision that our assumptions and definitions of disease are no longer consistent with the scientific evidence, and no longer serve our health care needs. The arc of scientific progress is now requiring a change in how we diagnose Alzheimer's disease. Both the National Institute on Aging-Alzheimer's Association (NIA-AA) 2011 workgroup and the International Work Group (IWG) have proposed guidelines that use detectable measures of biological changes in the brain, commonly known as biological markers, or biomarkers, as part of the diagnosis...

Acrolein is one of the most toxic byproducts of lipid peroxidation, and it has been shown to be associated with multiple pathological processes in trauma and diseases, including spinal cord injury, multiple sclerosis, and Alzheimer's disease. Therefore, suppressing acrolein using acrolein scavengers has been suggested as a novel strategy of neuroprotection. In an effort to identify effective acrolein scavengers, we have confirmed that dimercaprol, which possesses thiol functional groups, could bind and trap acrolein...

PRUNE2 has been identified as a susceptible gene for Alzheimer's disease and a marker for leiomyosarcomas. Isoforms of Prune2 regulate neuronal cell differentiation and synaptogenesis. Although expression pattern of Prune2 has been reported in the murine brain, its expression patterns and regulation along vertebrate embryogenesis remain to be further investigated. We thus defined the expression profiles and transcriptional regulation of prune2 in zebrafish embryos. prune2 exhibits maternal expression, but is increased in later embryonic stages, and expressed in the telencephalon, epiphysis cluster, nucleus of the tract of the post optic commissure, spinal cord, cerebellum, tegmentum, anterior lateral line ganglion, posterior lateral line ganglion and rhombomeres 2 through 5...

Since the discovery of aquaporins, it has become clear that the various mammalian aquaporins play critical physiological roles in water and ion balance in multiple tissues. Aquaporin-4 (AQP4), the principal aquaporin expressed in the central nervous system (CNS, brain and spinal cord), has been shown to mediate CNS water homeostasis. In this review, we summarize new and exciting studies indicating that AQP4 also plays critical and unanticipated roles in synaptic plasticity and memory formation. Next, we consider the role of AQP4 in Alzheimer's disease (AD), amyotrophic lateral sclerosis (ALS), Parkinson's disease (PD), multiple sclerosis (MS), neuromyelitis optica (NMO), epilepsy, traumatic brain injury (TBI), and stroke...

Until recently folate receptor alpha (FRα) has only been considered as a folate transporter. However, a novel role of FRα as a transcription factor was reported by our lab. More recently our lab showed a novel pleiotropic role of FRα: (a) direct transcriptional activation of Oct4, Sox2, and Klf4 genes; and (b) repression of biogenesis of miRNAs that target these genes or their effector molecules. These observations beg a question: "Can a simple molecule such as folate be used to manipulate the production and/or differentiation of endogenous neural stem cells (NSCs), which may hold promise for future therapies?" Conditions such as spinal cord injury, motor neuron diseases, Alzheimer's disease and multiple sclerosis may benefit from increasing stem cell pool and promoting specific pathways of differentiation...

Histone deacetylases (HDACs) are epigenetic enzymes creating the transcriptionally inactive state of chromatin by erasing acetyl moiety from histone and non-histone substrates. HDAC6 modulates several biological pathways in dividing cells as well as in post-mitotic neurons, and has been implicated in the pathophysiology of neurodegeneration. The distinct cellular functions and survival in these cells are reliant on HDAC6-mediated processes including intracellular trafficking, chaperone-mediated stress responses, anti-oxidation and protein degradation...

Synaptic loss and neuron death are the underlying cause of neurodegenerative diseases such as Alzheimer's disease (AD); however, the modalities of cell death in those diseases remain unclear. Ferroptosis, a newly identified oxidative cell death mechanism triggered by massive lipid peroxidation, is implicated in the degeneration of neurons populations such as spinal motor neurons and midbrain neurons. Here, we investigated whether neurons in forebrain regions (cerebral cortex and hippocampus) that are severely afflicted in AD patients might be vulnerable to ferroptosis...

The United States carries a substantial fiscal burden resulting from the nearly 100 million Americans with neurological disease. The combined annual costs of Alzheimer's and other dementias, low back pain, stroke, traumatic brain injury, migraine, epilepsy, multiple sclerosis, spinal cord injury and Parkinson's disease totals nearly 800 billion dollars and is rapidly rising due to the aging of the U.S. POPULATION: We provide a summary overview of the substantial current and future economic impact of neurological disease, and provide an action plan for reducing this burden through neurological research and enhanced clinical management of neurological disorders in the United States...

The high and increasing incidence of Alzheimer Disease (AD) worldwide is a major global concern. Classical diagnosis is carried out in the dementia phase, often in the moderate stages when treatment efficacy is limited. Nowadays, early diagnosis, even in pre-dementia stages, is possible in selected cases within an appropriate clinical setting, employing cerebral spinal fluid (CSF) sample analysis and neuroimaging procedures. In spite of the accurate diagnosis achieved by novel CSF biomarkers or positron emission tomography beta-amyloid tracers, these tests are invasive and expensive...

Accumulation of hyperphosphorylated tau directly correlates with cognitive decline in Alzheimer's disease and other primary tauopathies. One therapeutic strategy may be to reduce total tau expression. We identified antisense oligonucleotides (ASOs) that selectively decreased human tau mRNA and protein in mice expressing mutant P301S human tau. After reduction of human tau in this mouse model of tauopathy, fewer tau inclusions developed, and preexisting phosphorylated tau and Thioflavin S pathology were reversed...

Several independent studies indicate that microtubule (MT)-stabilizing agents hold considerable promise as candidate therapeutics for a wide spectrum of conditions of the central nervous system (CNS), from brain tumors to spinal cord injury, as well as a number of neurodegenerative diseases, including Alzheimer's disease, frontotemporal lobar degeneration, Parkinson's disease, and amyotrophic lateral sclerosis. Although the identification and development of candidate compounds for CNS-directed MT-stabilizing therapies has been a challenge in drug discovery for many years, a growing number of molecules have now been identified that exhibit both MT-stabilizing activity and brain penetration...

Microglia are the innate immune cells of the central nervous system (CNS) and play an important role in the maintenance of tissue homeostasis, providing neural support and neuroprotection. Microglia constantly survey their environment and quickly respond to homeostatic perturbations. Microglia are increasingly implicated in neuropathological and neurodegenerative conditions, such as Alzheimer's disease, Parkinson's disease, and glioma progression. Here, we describe a detailed isolation protocol for microglia and immune infiltrates, optimized for large amounts of post mortem tissue from human and rhesus macaque, as well as smaller tissue amounts from mouse brain and spinal cord, that yield a highly purified microglia population (up to 98 % purity)...

Astroglia are a morphologically diverse and highly abundant cell type in the CNS. Despite these obvious observations, astroglia still remain largely uncharacterized at the cellular and molecular level. In disease contexts such as amyotrophic lateral sclerosis (ALS), it has been widely shown that astroglia downregulate crucial physiological functions, become hypertrophied, reactive, and toxic to motor neurons. However, little is known about the astroglia-specific transcriptomic changes that occur during ALS disease progression, especially early in disease...

Amyloid precursor protein (APP), commonly associated with Alzheimer's disease, also marks axonal degeneration. In the recent studies, we demonstrated that APP aggregated at nodes of Ranvier (NORs) in myelinated central nervous system (CNS) axons and interacted with Nav1.6. However, the physiological function of APP remains unknown. In this study, we described reduced sodium current densities in APP knockout hippocampal neurons. Coexpression of APP or its intracellular domains containing a VTPEER motif with Nav1...

Evidence from laboratory studies and clinical trials suggests that plant-derived polyphenolic compounds such as curcumin, resveratrol, or phloretin might be useful in the treatment of certain diseases (e.g., Alzheimer's disease) and acute tissue injury states (e.g., spinal cord trauma). However, despite this potential, the corresponding chemical instability, toxic potential, and low bioavailability of these compounds could limit their ultimate clinical relevance. We have shown that pharmacophores of curcumin (e...

Cervical spinal cord stimulation is a well-established treatment for intractable neuropathic upper extremity pain. More than 20years ago it was demonstrated that cervical spinal cord stimulation could engender an increase in cerebral blood flow. Cerebral blood flow has been shown to be decreased in many patients with dementia and in various neurodegenerative disorders such as Alzheimer's disease and Parkinson's disease. Furthermore, there is evidence that reduced cerebral blood flow worsens neurodegenerative disease and may also predict which patients progress from mild cognitive impairment to full blown Alzheimer's disease...

The peripheral (PNS) and central nervous system (CNS) are delicate structures, highly sensitive to homeostatic changes-and crucial for basic vital functions. Thus, a selection of barriers ensures the protection of the nervous system from noxious blood-borne or surrounding stimuli. In this chapter, anatomy and functioning of the blood-nerve (BNB), the blood-brain (BBB), and the blood-spinal cord barriers (BSCB) are presented and the key tight junction (TJ) proteins described: claudin-1, claudin-3, claudin-5, claudin-11, claudin-12, claudin-19, occludin, Zona occludens-1 (ZO-1), and tricellulin are by now identified as relevant for nerval barriers...

Aquaporins (AQPs) are water channel proteins robustly expressed in the central nervous system (CNS). A number of previous studies described the cellular expression sites and investigated their major roles and function in the brain and spinal cord. Among thirteen different mammalian AQPs, AQP1 and AQP4 have been mainly studied in the CNS and evidence has been presented that they play important roles in the pathogenesis of CNS injury, edema and multiple diseases such as multiple sclerosis, neuromyelitis optica spectrum disorders, amyotrophic lateral sclerosis, glioblastoma multiforme, Alzheimer's disease and Parkinson's disease...
