BACKGROUND: Multiple Sclerosis (MS) refers to a chronic inflammation of the central nervous system including the brain and spinal cord. Dysphagia is one of the symptoms that represent challenges in clinical practice for the management of MS patients. Dysphagia can result in serious complications leading to morbidity and death in late stages of MS. However, little attention is given to dysphagia, its symptoms and how it affects the quality of life of adults with MS. OBJECTIVES: The purpose of this study is to identify the frequency of dysphagia in adults with MS and determine the main symptoms suggestive of dysphagia and its impact on the patients' quality of life...

Early brain injury (EBI) after aneurysmal subarachnoid hemorrhage (SAH) contributes to high morbidity and mortality. Although it is well recognized that acute neuroinflammation reaction is one of the most important triggers of EBI, pharmacotherapy proved to be clinically effective against the initiating of neuroinflammation after SAH is lacking. The resident microglia and infiltrated peripheral monocyte are two main types of immune cells in central nervous system (CNS) and control the inflammation process in brain after SAH...

The cytokine transforming growth factor (TGF)-β1 is highly induced after encephalopathic brain injury, with data showing that it can both contribute to the pathophysiology and aid in disease resolution. In the immature brain, sustained TGFβ-signaling after injury may prolong inflammation to both exacerbate acute stage damage and perturb the normal course of development. Yet in adult encephalopathy, elevated TGFβ1 may promote a reparative state. In this review, we highlight the context-dependent actions of TGFβ-signaling in the brain during resolution of encephalopathy and focus on neuronal survival mechanisms that are affected by TGFβ1 ...

Brain-derived neurotrophic factor (BDNF) is one of the most studied neurotrophins in the healthy and diseased brain. As a result, there is a large body of evidence that associates BDNF with neuronal maintenance, neuronal survival, plasticity, and neurotransmitter regulation. Patients with psychiatric and neurodegenerative disorders often have reduced BDNF concentrations in their blood and brain. A current hypothesis suggests that these abnormal BDNF levels might be due to the chronic inflammatory state of the brain in certain disorders, as neuroinflammation is known to affect several BDNF-related signaling pathways...

Hemorrhagic transformation (HT) is a serious complication that stimulates inflammation during reperfusion therapy after acute ischemic stroke. Rosuvastatin, a 3-hydroxymethyl-3-methylglutaryl coenzyme A (HMG-CoA) reductase inhibitor, might improve the outcome of HT by inhibiting neuroinflammation. This study aimed to explore the protective effects of rosuvastatin against HT after recombinant tissue plasminogen activator (rt-PA) treatment in mice with experimental stroke via the attenuation of inflammation. A total of one hundred sixty-nine male BALB/c mice were used in the experiment...

Sonic hedgehog (Shh), a member of the hedgehog (Hh) family, was originally recognized as a morphogen possessing critical characters for neural development during embryogenesis. Recently, however, Shh has emerged as an important modulator in adult neural tissues through different mechanisms such as neurogenesis, anti-oxidation, anti-inflammation, and autophagy. Therefore, Shh may potentially have clinical application in neurodegenerative diseases and brain injuries. In this article, we present some examples, including ours, to show different aspects of Shh signaling and how Shh agonists or mimetics are used to alter the neuronal fates in various disease models, both in vitro and in vivo...

Health authorities are alarmed worldwide about the increase of obesity and overweight in the last decades which lead to adverse health effects including inflammation, cancer, accelerated aging and infertility. We evaluated the state of knowledge concerning the impact of elevated body mass on genomic instability. Results of investigations with humans (39 studies) in which DNA damage was monitored in lymphocytes and sperm cells, are conflicting and probably as a consequence of heterogeneous study designs and confounding factors (e...

BACKGROUND: Sellar infections represent less than 1% of all sellar lesions and can be life-threatening. These infections occur de novo in up to 70% of patients, or can less commonly develop after surgical treatment of another primary lesion, such as a pituitary adenoma. CASE DESCRIPTION: We report a unique case of a 27 year-old woman with a recurrent pituitary adenoma treated with two prior transsphenoidal resections. She ultimately presented with hypopituitarism, followed by headaches, malaise, chills, and visual field and acuity deficits nine years after her second transsphenoidal resection...

Midkine (Mdk)is a cytokine involved in controlling tissue repair and new tissue development, and regulating inflammation involved in several signaling pathway, such as the mitogen-activated protein kinase (MAPK) and phosphatidyl inositol 3-kinase (PI3K)/AKT pathways. But the role of Mdk in the development of Cynoglossus semilaevis is poorly understood. In this study, the Midkine of C. semilaevis (CsMdk) was cloned, and its spatiotemporal expression pattern and structural characteristics were analyzed. Furthermore, the essential genes related to nervous system development and germ layer formation marker gene were identified by qRT-PCR and in situ hybridization after overexpression the CsMdk via zebrafish model...

OBJECTIVE: Here, we applied a multi-omics approach (i) to examine molecular pathways related to de- and remyelination in multiple sclerosis (MS) lesions; and (ii) to translate these findings to the CSF proteome in order to identify molecules that are differentially expressed among MS subtypes. METHODS: To relate differentially expressed genes in MS lesions to de- and remyelination, we compared transcriptome of MS lesions to transcriptome of cuprizone (CPZ)-induced de- and remyelination...

Inflammation is implicated in epileptogenesis. Activated microglia and macrophages (MG/MΦ) are found in the brains of patients with epilepsy-related diseases and animal models of epilepsy. It is not yet known how the MG/MΦ activation phenotype affects pathological changes in the brain after a single seizure. In this study, we had 2 main purposes: first, to characterize post-status epilepticus (SE) inflammation by tracking MG/MΦ polarization, and, second, to explore the role of an innate immune receptor adaptor protein, namely, myeloid differentiation primary response gene 88 (MyD88), in the induction of SE in a mouse model...

The aim of the study was to find out scientific evidence on the possible use of the combined angiotensin II receptor antagonist and neprilysin inhibitors (ARNI) in patients with right heart failure (RHF) in the course of chronic obstructive pulmonary disease (COPD). It has been proven that a lack of neprilysin or its reduced expression in hypoxia leads to exacerbation of pulmonary arterial remodelling (PAR) or pulmonary hypertension (PH) in the mechanism related to the platelet-derived growth factor (PDGF) resulting in the proliferation and migration of pulmonary artery smooth muscle cells and endothelial-to-mesenchymal transition...

Aging is often accompanied by a decline in cognitive function in conjunction with a variety of neurobiological changes, including neuroinflammation. Melatonin is a key endogenous indoleamine secreted by the pineal gland that plays a crucial role in the regulation of circadian rhythms, is a potent free radical scavenger, has anti-inflammatory activity and serves numerous other functions. However, the role of melatonin in sterile inflammation in the brain has not been fully investigated. In the present study, we investigated the neuroinflammation status in aged mouse brains...

BACKGROUND: Inflammation has been found to be associated with many neurodegenerative diseases, including Parkinson's and dementia. Attenuation of microglia-induced inflammation is a strategy that impedes the progression of neurodegenerative diseases. METHODS: We used lipopolysaccharide (LPS) to simulate murine microglia cells (BV2 cells) as an experimental model to mimic the inflammatory environment in the brain. In addition, we examined the anti-inflammatory ability of corylin, a main compound isolated from Psoralea corylifolia L...

Hyperbilirubinemia (jaundice) is caused by raised levels of unconjugated bilirubin in the blood. When severe, susceptible brain regions including the cerebellum and auditory brainstem are damaged causing neurological sequelae such as ataxia, hearing loss and kernicterus. The mechanism(s) by which bilirubin exerts its toxic effect have not been completely understood to date. In this study we investigated the acute mechanisms by which bilirubin causes the neurotoxicity that contributes to hearing loss. We developed a novel mouse model that exhibits the neurological features seen in human Bilirubin-Induced Neurological Dysfunction (BIND) syndrome that we assessed with a behavioural score and auditory brainstem responses (ABR)...

Bacterial meningitis in neonates and infants is an acute lethal disease and occurs in response to microbial exploitation of the blood brain barrier (BBB), resulting in the intracranial inflammation. Several pathogens, such as Escherichia coli (E. coli), can cause this devastating disease; however, the underlying molecular mechanisms by which these pathogens exploit the BBB remain incompletely understood. To identify important players on both the pathogen and host sides that govern the E. coli-BBB cell interactions, we took advantage of the E...
