OBJECTIVES: Interferon-β 1a (IFN-β 1a) is a common strategy therapy for multiple sclerosis (MS) with unknown mechanisms. S100A12 (S100 calcium-binding protein A12) is a damage-associated molecular pattern molecule which binds to its receptor, RAGE (receptor for advanced glycation end products), and activates nuclear factor-κB (NF-κB). NF-κB is transcribed from proinflammatory molecules, which may participate in the pathogenesis of MS. Therefore, the aims of this study were to compare mRNA levels of S100A12, RAGE, and NF-κB in newly diagnosed MS patients with healthy controls and determine whether IFN-β 1a therapy affects the expression of the molecules...

OBJECTIVE: Aquaporin-4 (AQP4), a key molecule for water homeostasis in the brain, is associated with adult neurogenesis, but its mechanisms regulating adult neural stem cells (aNSC) remain largely unexplored. Neuroinflammation has a relevant influence on adult neurogenesis, which is a common feature in various neurodegenerative diseases. Considering the possible link between neuroinflammation and AQP4, we speculate that AQP4 may mediate the synthesis and release of proinflammatory cytokines in glia and then indirectly regulate adult hippocampal neurogenesis...

OBJECTIVE: Mesial temporal lobe epilepsy (MTLE) is the most common type of refractory epilepsy. It is often associated with hippocampal sclerosis, which is histopathologically characterized by selective neuron loss, mossy fiber sprouting, and synapse reconstruction, and is the primary cause of refractory epilepsy. Its mechanism has not been fully elucidated. Substantial evidence now supports that inflammatory pathways are activated in epilepsy foci. We have confirmed that the interleukin-1β (IL-1β) level is involved in the epileptogenesis of MTLE, and we further investigated how it works in its chronicity in this study...

OBJECTIVE: Chronic inflammatory processes contribute to the eventual death of motor neurons and the development of symptoms in both idiopathic Parkinson disease (PD) and multiple system atrophy (MSA). Given the faster rate of progression and more severe symptoms associated with MSA, we hypothesized that markers of inflammation would be more evident in the peripheral blood of MSA than PD patients, and that evidence of this inflammation might assist early diagnosis of MSA versus PD. METHODS: We performed multiplex analysis to determine the concentrations of 37 immune-associated cytokines and chemokines isolated from the plasma of patients with PD (n = 25) and MSA (n = 14) and compared our results to those of age-matched controls (n = 15)...

There is a growing interest in hair cortisol concentrations as a valuable biomarker for the assessment of metabolic diseases and chronic psychological stress. Fifty-three volunteers were recruited, and hair segments proximal to the scalp were collected from each individual. A cost-effective ball mill was used for the preparation of hair samples, and ELISA was performed to analyze cortisol concentrations. Results indicate that the frequency of hair washing affects the hair cortisol concentration. The group that washed their hair every day had significantly lower cortisol concentrations than the group that washed it less often...

OBJECTIVE: Japanese encephalitis (JE) is a debilitating disease caused by infection with the JE virus (JEV; family: Flaviviridae), which leaves neurological sequelae in survivors but more often leads to mortality. Neurodegeneration caused by inflammation is the primary pathology behind the clinical manifestation of encephalitis caused by JEV. Bacillus Calmette-Guérin (BCG) has been used in immunoprophylaxis for tuberculosis and in the adjuvant therapy of many malignancies, and has exhibited neuroprotective activities in experimental models of Parkinson and Alzheimer disease...

OBJECTIVE: Hydrogen sulfide (H2S), as a novel gasotransmitter, plays important roles in a number of physiological and pathological processes. Its effectiveness has been demonstrated in different types of brain disorders but not in repetitive febrile seizure (febrile status epilepticus; FSE) models. This study aims to test whether a donor of H2S sodium sulfhydrate (NaHS) is also effective for FSE in rats. METHODS: FSE was induced in rat pups on postnatal day 10 in water at 45...

BACKGROUND/AIM: Neonatal infection can sensitize the adult substantia nigra (SN) to secondary insults, causing a decrease in antioxidant capacity which may lead to Parkinson's disease in adults. We studied the prolonged effect of systemic infection by (i.p.) administration of lipopolysaccharide (LPS) on interleukin (IL)-1β, the antioxidant regulator nuclear factor-erythroid 2-related factor 2 (Nrf2), and the peroxisome proliferator-activated receptor γ coactivator (PGC)-1α in rat SN...

Fragile X syndrome (FXS) is the most common form of familial mental retardation and one of the leading known causes of autism. The mutation responsible for FXS is a large expansion of the CGG repeats in the promoter region of the FMR1 gene, resulting in the transcriptional silencing of the gene. Leptin may be considered a cytokine-like hormone with pleiotropic actions since it may be involved in the regulation of neuroendocrine functions and the immune system response, in addition to playing a role in development...

Both cellular and molecular components of the immune system are among the substantial factors involved in the pathogenesis of multiple sclerosis (MS). Accumulating evidence confirms that chemokines, as the main members of the immune system, play key roles in the regulation of immune responses. Immune system genetic parameters are believed to influence the onset of immune system-related diseases. Regarding the significant role of the CXCR4/CXCL12 axis in cell differentiation and survival and homing of hematopoietic progenitors to the bone marrow and regulation of neuronal progenitor cell migration in the central nervous system (CNS), genetic factors can cause an increased expression of CXCL12 and induce a vigorous immune response against CNS antigens in MS patients...

OBJECTIVE: Minocycline, a tetracycline antibiotic, has shown anti-inflammatory effects in cerebral ischemia and neurodegenerative disease; however, the molecular mechanisms underlying this effect have not been clearly identified. Since NLRP3 inflammasome activation controls the maturation and release of proinflammatory cytokines, especially interleukin-1β (IL-1β) and IL-18 in ischemia stroke, we suppose that minocycline may be involved in the regulation of NLRP3 inflammasome activation...

OBJECTIVE: Activation of STAT1 is directly downstream of the cytokine receptors that signal from specific proinflammatory cytokines known to be dysregulated in schizophrenia (SZ), such as IFNγ, IL6, IL2 and IL10, as well as hypoxia, viral/bacterial infections and peptide growth factors. If the increased cytokine protein levels repeatedly observed in SZ have biological consequences, then the measurement of pSTAT1 is a logical step forward. METHODS: Peripheral blood mononuclear cells (PBMCs) from controls (n = 13) and subjects with SZ (n = 22) were extracted using the Ficoll method...

OBJECTIVES: Curcumin, a naturally occurring compound derived from turmeric (Curcuma longa) has long been suggested to have strong therapeutic or preventive potential against human diseases because of its antioxidative, anticancerous, and anti-inflammatory effects. Curcumin is known to exert anti-inflammatory effects by interrupting NF-κB signaling at multiple levels. Many observations indicate that curcumin shows its valuable potential by inhibiting the activity of I-κB kinase. Transglutaminase 2 (TG2) expression is increased in inflammatory diseases...

OBJECTIVE: It is well known that Schwann cells play an important role in Wallerian degeneration after peripheral nerve injury. Previously, we reported that toll-like receptor 3 (TLR3) is expressed on Schwann cells, implicating its role in Schwann cell activation during Wallerian degeneration. In this study, we tested this possibility using TLR3 knock-out mice. METHODS: Sciatic nerve-crush injury was induced in wild-type and TLR3 knock-out mice. Histological sections of the sciatic nerve were analyzed for Wallerian degeneration on days 3 and 7 after injury...
