Optimization of the Light-On system in a lentiviral platform to a light-controlled expression of genes in neurons

BACKGROUND: Molecular brain therapies require the development of molecular switches to control gene expression in a limited and regulated manner in time and space. Light-switchable gene systems allow precise control of gene expression with an enhanced spatio-temporal resolution compared to chemical induc...

The neuroprotection of cerebrolysin after spontaneous intracerebral hemorrhage through regulates necroptosis via Akt/ GSK3B signaling pathway

Acta cir. bras; 36 (10), 2021
ABSTRACT Purpose: Spontaneous intracerebral hemorrhage (ICH) is a major cause of death and disability with a huge economic burden worldwide. Cerebrolysin (CBL) has been previously used as a nootropic drug. Necroptosis is a programmed cell death mechanism that plays a vital role in neuronal cell death af...

Errores innatos metabólicos en parálisis cerebral: estudio en 174 infantes
Inborn errors of metabolism in 174 cases of cerebral palsy

La Parálisis Cerebral (PC) es un conjunto de alteraciones motrices no progresivas en la población infantojuvenil, ocasionadas por lesión –a nivel cerebral- de neuronas o fibras de esa vía, de sus aferencias o de las que la modulan; para su diagnóstico deben conocerse otras patologías también fre...

Neuroprotective Effect of Isobenzofuranones on Hydrogen Peroxide-Mediated Redox Imbalance in Primary Cultures of Hippocampal Neurons

Abstract In live organisms, there is a balance between the production of reactive oxygen species (ROS) and their neutralization. The increased level of these species leads to a condition called redox imbalance. The aim of this study was to evaluate the protective action of isobenzofuranones in primary cu...

Toxoplasma gondii infection damages the perineuronal nets in a murine model

Mem. Inst. Oswaldo Cruz; 115 (), 2020
BACKGROUND Behavioral and neurochemical alterations associated with toxoplasmosis may be influenced by the persistence of tissue cysts and activation of an immune response in the brain of Toxoplasma gondii-infected hosts. The cerebral extracellular matrix is organised as perineuronal nets (PNNs) that ar...

Effect of periapical inflammation on calcium binding proteins and ERK in the trigeminal nucleus

Acta odontol. latinoam; 32 (2), 2019
Peripheral inflammation induces plastic changes in neurons and glia which are regulated by free calcium and calcium binding proteins (CaBP). One of the mechanisms associated with the regulation of intracellular calcium is linked to ERK (Extracellular Signal-Regulated Kinase) and its phosphorylated condit...

Dinámica mitocondrial en las enfermedades neurodegenerativas

Gac. méd. Méx; 155 (3), 2019
Resumen Las enfermedades neurodegenerativas son un grupo heterogéneo caracterizado por la disminución gradual, progresiva y selectiva de las funciones del sistema nervioso. La etiología de estas patologías aún se desconoce, sin embargo, se ha propuesto que la función mitocondrial pudiese estar part...

The effect of CA1 administration of orexin-A on hippocampal expression of COX-2 and BDNF in a rat model of orofacial pain

Arq. neuropsiquiatr; 76 (9), 2018
ABSTRACT The neuropeptide orexin-A and its receptors are widely distributed in both hippocampal circuitry and pain transmission pathways. Objective: Involvement of the CA1 orexin 1 receptor (OX1R) on the modulation of orofacial pain and pain-induced changes in hippocampal expression of cyclooxygenase-2 ...

Neuron-derived CCL2 contributes to microglia activation and neurological decline in hepatic encephalopathy

Biol. Res; 50 (), 2017
BACKGROUND: CCL2 was up-regulated in neurons and involved in microglia activation and neurological decline in mice suffering from hepatic encephalopathy (HE). However, no data exist concerning the effect of neuron-derived CCL2 on microglia activation in vitro. METHODS: The rats were pretreated with CCL2 ...

Knockdown of interleukin-10 induces the redistribution of sigma1-receptor and increases the glutamate-dependent NADPH-oxidase activity in mouse brain neurons

Biol. Res; 48 (), 2015
BACKGROUND: In the central nervous system, interleukin-10 (IL-10) provides trophic and survival effects directly on neurons, modulates neurite plasticity, and has a pivotal importance in the neuronal regeneration in neurodegenerative and neuroinflammatory conditions. This cytokine is primarily produced b...
