In April 2015, the US Food and Drug Administration approved the first generic glatiramer acetate, Glatopa® (M356), as fully substitutable for Copaxone® 20 mg/mL for relapsing forms of multiple sclerosis (MS). This approval was accomplished through an Abbreviated New Drug Application that demonstrated equivalence to Copaxone. In vitro and in vivo experiments from multiple redundant orthogonal assays within four biological processes (aggregate biology, antigen-presenting cell biology, T-cell biology, and B-cell biology) modulated by glatiramer acetate in MS established the biological and immunological equivalence of Glatopa and Copaxone and are described...

Suicide risk is a major cause of death among patients with schizophrenia. Death by suicide has been reported in approximately 5% of schizophrenia patients although such figure appears an underestimation of the problem. A number of risk factors are routinely reported as associated with suicide risk among these patients, some of which are modifiable by targeted therapeutic strategies. Clozapine is the only compound that gathered evidence as an effective treatment for reducing suicide risk in schizophrenia. Long-Acting Injectable Antipsychotics (LAIs) have a range of advantages in terms of efficacy, safety and tolerability in the treatment of schizophrenia, and one area of interest is whether LAI-treatment may decrease suicidality by indirectly acting on a range of risk factors for suicide specific to schizophrenia patients...

Cannabinoids are derivatives that are either compounds occurring naturally in the plant, Cannabis sativa or synthetic analogs of these molecules. The first and most widely investigated of the cannabinoids is ∆9-tetrahydrocannabinol (Δ9-THC), which is the main psychotropic constituent of cannabis and undergoes significant binding to cannabinoid receptors. These cannabinoid receptors are seven-transmembrane receptors that received their name from the fact that they respond to cannabinoid compounds, including Δ9-THC...

Cerebral small vessel diseases (CSVDs) always coincide with endothelial dysfunction and blood-brain barrier (BBB) damage. Granulocyte-colony stimulating factor (G-CSF) can play a neuroprotective role in many neurological diseases. We investigated whether G-CSF exerts positive effects in spontaneously hypertensive rats (SHRs), a rat model of CSVD. Twenty-four-week-old SHRs, displaying the early histopathological changes of CSVD, received daily administrations of either G-CSF (50μg/kg) or saline for 7 days. The novel object recognition test was then conducted after treatment...

Chronic severe pain is treated most successfully with opioid analgesics, although the clinical use of these drugs is constrained by unwanted side effects, including the potential for abuse. GABAergic neurons are located in spinal nociceptive circuits suggesting that drugs with affinity at these receptors, including benzodiazepine-like drugs, may provide an alternative to opioids for the treatment of pain. However, systemically administered conventional benzodiazepines fail to produce antihyperalgesic effects, likely due to their concurrent sedative properties...

Selective butyrylcholinesterase (BuChE)-inhibition, increases acetylcholine (ACh) levels. In rodents, this inhibition is known to boost cognition. Also, this occurs without the typical unwanted effects of acetylcholinesterase-inhibitors or AChE-Is. The novel compound, fluorobenzylcymserine (FBC), is derived from our effort to design a selective BuChE-inhibitor. Also, we wanted to check whether butyrylcholinesterase-inhibitors (BuChE-Is) possessed an edge over AChE-Is in Alzheimer's disease (AD) in terms of efficacy and/or tolerance...

Inflammatory responses are important mechanisms that are involved in cerebral ischemia/reperfusion(I/R) injury. Whether toll-like receptor 9(TLR9), which belongs to the innate immune system, takes part in the inflammatory responses following cerebral I/R remains unclear. This study examined the effect of different dosages of the TLR9 antagonist inhibitory oligodeoxynucleotide (iCpG-ODN) on cerebral I/R injury by using a mouse model of transient middle cerebral artery occlusion. Neurological function, infarct size, splenocytes and the expression of TLR9 and the downstream products of the TLR9 pathways were determined after cerebral I/R for up to 72 hours...

BACKGROUND: Parkinson's disease (PD) is a neurodegenerative disorder with a prevalence increasing with age. Oxidative stress and glutamate toxicity are involved in its pathomechanism. There are still many unmet needs of PD patients, including the alleviation of motor fluctuations and dyskinesias, and the development of therapies with neuroprotective potential. OBJECTIVE: To give an overview of the pharmacological properties, the efficacy and safety of the monoamine oxidase B (MAO-B) inhibitors in the treatment of PD, with special focus on the results of randomized clinical trials...

BACKGROUND: Pyrroloquinoline quinoe is an anionic, water-soluble compound with antioxidant characteristic. The role of pyrroloquinoline quinoe in pharmacology and nutrition has attracted wide attention of researchers. Although a few experiments have confirmed that pyrroloquinoline quinoe plays an obvious effective role in neuroprotection. There are little reports about the effect of pyrroloquinoline quinoe in traumatic brain injury. Traumatic brain injury is one of the leading causes of adult disability and death in the world...

Amyloid based hypothesis led to develop biomarkers oriented diagnosis of neurodegenerative dementias. Among them biomarkers for AD, the most diffuse form of dementia, are currently the unique available for scientific and diagnostic purposes. CSF biomarkers like Amyloid beta 42, total tau and phosphorylated tau levels can be easily evaluated in individuals suffering from cognitive decline, to diagnose or exclude AD type dementia, since early stages. Moreover, their analysis gave the opportunity to better understand cognitive decline patho-physiology during aging...

Epilepsy is one of the most common neurological disorders in humans, and the role of the cerebellum in its physiopathology remains the subject of study. The Purkinje cells (PC), whose axons target the dentate and interpositus nuclei, form the main cerebellar output to forebrain structures involved in epilepsy. Cerebellar atrophy related to loss of PC has been reported in chronic epilepsy although its mechanism remains unclear. Taking in account that an overexpression of β-Catenin has been related with cell death, here we present the signaling of β-Catenin and the type of PC death in cerebellum of rats with chronic seizures induced by the amygdaloid kindling model...

The blood brain barrier (BBB) is a continuous, non-fenestrated vessel system that tightly regulates the movement of molecules, ions, and cells between the blood and the central nervous system. Endothelial cells are the major constituents of the BBB and these cells are linked to each other through intercellular contact points composed of tight junctions, adherent junctions and gap junctions. These three types of junctions are connected to the intracellular actin cytoskeleton via various adaptor proteins. Thus, the actin cytoskeleton plays a crucial role in regulating the stability of endothelial cell contacts and vascular permeability...

BACKGROUND: Alzheimer's disease (AD) therapy is based on several natural and synthetic compounds that act as acetylcholinesterase (AChE) and N-methyl-D-aspartate receptor (NMDA) ligands that have limited efficiency in relieving AD symptoms. Recent studies show that inhibitors isolated from Mentha spicata L. subsp. spicata are promising for AD therapy. OBJECTIVE: We aimed to identify novel and more potent phytopharmaceutical compounds for AD treatment by taking into account the compounds from Mentha spicata L...

Neuroplasticity is not only shaped by learning and memory but is also a mediator of responses to neuron attrition and injury (compensatory plasticity). As an ongoing process it reacts to neuronal cell activity and injury, death, and genesis, which encompasses the modulation of structural and functional processes of axons, dendrites, and synapses. The range of structural elements that comprise plasticity includes long-term potentiation (a cellular correlate of learning and memory), synaptic efficacy and remodelling, synaptogenesis, axonal sprouting and dendritic remodelling, and neurogenesis and recruitment...

In this paper, we propose an automatic brain tumor segmentation method based on Deep Belief Networks (DBNs) and pathological knowledge. The proposed method is targeted against gliomas (both low and high grade) obtained in multi-sequence magnetic resonance images (MRIs). Firstly, a novel deep architecture is proposed to combine the multi-sequences intensities feature extraction with classification to get the classification probabilities of each voxel. Then, graph cut based optimization is executed on the classification probabilities to strengthen the spatial relationships of voxels...

Central nervous system diseases are major health issues and are often associated with disability or death. Most central nervous system disorders are characterized by high levels of oxidative stress. Nuclear factor erythroid 2 related factor (Nrf2) is known for its ability to regulate the expression of a series of enzymes with antioxidative, prosurvival, and detoxification effects. Under basal conditions, Nrf2 forms a complex with Kelch-like ECH associated protein 1, leading to Nrf2 inactivation via ubiquitination and degradation...

BACKGROUND: Motoneurons with naturally elevated calcium binding protein content, such as parvalbumin, are more resistant against injury. Furthermore, increase of intracellular calcium, which plays a pivotal role in injury of neurons, could be moderated by elevating their calcium binding proteins. OBJECTIVE: To test whether by elevating parvalbumin content of motoneurons, activation of neighboring microglial cells, a robust component of the inflammatory reaction after injury, could be influenced...

Cognitive impairment is a major manifestation of schizophrenia and a crucial treatment target as these deficits are closely related to patients' functional outcomes. Cognitive remediation is the gold-standard practice to address cognitive deficits in schizophrenia. There is clear evidence stating that cognitive remediation improves cognitive function and promotes structural neuroplastic changes in patients with schizophrenia, with brain-derived neurotrophic factor (BDNF) expression emerging as a potential biomarker for its efficacy...

Brain lesions, especially White Matter Lesions (WMLs) that mostly found on magnetic resonance images of elderly people, are not only associated with normal aging, but also with various geriatric disorders including cardiovascular diseases, vascular disease, psychiatric disorders and dementia. Quantitative analysis of WMLs in large clinical trials is crucial in scientific investigations of such neurological diseases as well as in studying aging processes. Exploiting the different appearances of WMLs in multiple modalities, we propose a novel coarse classification to region-scalable refining method to segment WMLs in Magnetic Resonance Imaging (MRI) sequences without user intervention...
