APP depletion alters selective pre- and post-synaptic proteins
(Elsevier, 2019-03)
The normal role of Alzheimer's disease (AD)-linked amyloid precursor protein (APP) in the brain remains incompletely understood. Previous studies have reported that lack of APP has detrimental effects on spines and ...
Co-administration of Anti microRNA-124 and -137 Oligonucleotides Prevents Hippocampal Neural Stem Cell Loss Upon Non-convulsive Seizures
(Frontiers Media, 2019-02-19)
Convulsive seizures promote adult hippocampal neurogenesis (AHN) through a transient activation of neural stem/progenitor cells (NSPCs) in the subgranular zone (SGZ) of the dentate gyrus (DG). However, in a significant ...
High-Altitude Cognitive Impairment Is Prevented by Enriched Environment Including Exercise via VEGF Signaling
(Frontiers Media, 2019)
Exposure to hypobaric hypoxia at high altitude (above 2500 m asl) causes cognitive impairment, mostly attributed to changes in brain perfusion and consequently neuronal death. Enriched environment and voluntary exercise ...
Amyotrophic lateral sclerosis: a complex syndrome that needs an integrated research approach
(Wolters Kluwer, 2019-02)
Amyotrophic lateral sclerosis, the most common neurodegenerative disease affecting motor neurons, lacks an effective treatment. A small fraction of amyotrophic lateral sclerosis cases have a familial origin, related to ...
Delivery of microRNAs as a remyelination strategy in multiple sclerosis.
(2019-01-18)
La esclerosis múltiple es una enfermedad del sistema nervioso central para la cual no existen fármacos que promuevan la remielinización. Por ello, la comunidad científica está realizando un gran esfuerzo por desarrollar ...
Parkinson disease-associated mutations in LRRK2 cause centrosomal defects via Rab8a phosphorylation
(Biomed Central, 2019-01-23)
Background: Mutations in LRRK2 are a common genetic cause of Parkinson's disease (PD). LRRK2 interacts with and phosphorylates a subset of Rab proteins including Rab8a, a protein which has been implicated in various ...
Perspective: Of Mice and Men - How Widespread Is Adult Neurogenesis?
(Frontiers Media, 2019-08-29)
These are exciting times for research on adult hippocampal neurogenesis (AHN). Debate and controversy regarding the existence of generation of new neurons in the adult, and even diseased human brain flourishes as articles ...
Delayed Diagnosis of an Eating Disorder in a Male Patient With Superior Mesenteric Artery Syndrome: Results From a Case Study
(Frontiers Media, 2019-10-15)
Background: Eating disorders (EDs) are serious and life-threatening mental diseases characterized by abnormal or altered eating habits. The prevalence is variable, being influenced by diverse sociocultural factors. ...
Impacto de la estimulación subtalámica a largo plazo sobre la situación cognitiva de los pacientes con enfermedad de Parkinson avanzada
(Elsevier, 2019-06-13)
Objetivo
El objetivo es evaluar los efectos de la estimulación cerebral profunda del núcleo subtalámico bilateral (STN-DBS) sobre el estado cognitivo de los pacientes con enfermedad de Parkinson 5 años después de la ...
Circadian glucocorticoid oscillations preserve a population of adult hippocampal neural stem cells in the aging brain
(Springer, 2019-06-20)
A decrease in adult hippocampal neurogenesis has been linked to age-related cognitive impairment. However, the mechanisms involved in this age-related reduction remain elusive. Glucocorticoid hormones (GC) are important ...
