Knowledge of the potential effect of genetic background in disease models is important. The SOD1-G93A transgenic mouse is the most widely used model in amyotrophic lateral sclerosis (ALS). Since these animals show considerable variability both in the onset and the progression of the disease, this study aimed to characterize the potential differences between(More)
Multiple Sclerosis (MS) is an acquired inflammatory demyelinating disorder of the central nervous system (CNS) and is the leading cause of nontraumatic disability among young adults. Activated microglial cells are important effectors of demyelination and neurodegeneration, by secreting cytokines and others neurotoxic agents. Previous studies have(More)
The cdk inhibitor p21(Cip1), also named p21(Cip1/Waf1), is intimately involved in coupling growth arrest to cellular differentiation in several cell types. p21(Cip1) is a multifunctional protein that might regulate cell-cycle progression at different levels. In a recent study, we found no differences in the rate of proliferation between glial cells from(More)
The transcription factor CCAAT/enhancer binding protein δ (C/EBPδ) is expressed in activated astrocytes and microglia and can regulate the expression of potentially detrimental proinflammatory genes. The objective of this study was to determine the role of C/EBPδ in glial activation. To this end, glial activation was analyzed in primary glial cultures and(More)
Pharmacological modulation of ATP-sensitive potassium channels has become a promising new therapeutic approach for the treatment of neurodegenerative diseases due to their role in mitochondrial and cellular protection. For instance, diazoxide, a well-known ATP-sensitive potassium channel activator with high affinity for mitochondrial component of the(More)
The transcription factor CCAAT/enhancer binding protein delta (C/EBP delta) regulates transcription of genes that play important roles in glial activation. Previous studies have shown the astroglial expression of C/EBP delta but the microglial expression of C/EBP delta remains virtually unexplored, with the exception of two microarray studies. In this(More)
Neuroinflammation is thought to play a pathogenic role in many neurodegenerative disorders including amyotrophic lateral sclerosis (ALS). In this study we demonstrate that the expression of nitric oxide (NO) synthase-2 (NOS2), and cyclooxygenase (COX)-2 induced by lipopolysaccharide (LPS) with interferon-γ is higher in microglial-enriched cultures from(More)
Activation of mitochondrial ATP-sensitive potassium (KATP) channels is postulated as an effective mechanism to confer cardio and neuroprotection, especially in situations associated to oxidative stress. Pharmacological activation of these channels inhibits glia-mediated neuroinflammation. In this way, diazoxide, an old-known mitochondrial KATP channel(More)
Many neurodegenerative diseases are associated, at least in part, to an inflammatory process in which microglia plays a major role. The effect of the triglyceride form of the omega-3 polyunsaturated fatty acid docosahexaenoic acid (TG-DHA) was assayed in vitro and in vivo to assess the protective and anti-inflammatory activity of this compound. In the in(More)
