Regulation of developing myelin sheath elongation by oligodendrocyte calcium transients in vivo
(NATURE PUBLISHING GROUP, 2018-01)How action potentials regulate myelination by oligodendrocytes is uncertain. We show that neuronal activity raises [Ca2+](i) in developing oligodendrocytes in vivo and that myelin sheath elongation is promoted by a high ... -

(Chile. Universidad Mayor, 2021-08-20)El Doctor en Ciencias Biológicas e investigador del Centro de Biología Integrativa de la Universidad Mayor, Erick Riquelme, aborda el proceso de los tumores, los principales tratamientos, los últimos hallazgos para futuros ... -
La Ruta del Pensamiento: ¿Qué sabemos de las enfermedades que afectan al cerebro?
(Chile. Universidad Mayor, 2021-07-28)René Vidal, Doctor en Ciencias y académico del Centro de Biología Integrativa U. Mayor, realizó el webinar “¿Qué sabemos de las enfermedades que afectan al cerebro?”, donde profundizó en su funcionamiento y qué ocurre ... -
Salmonella Type III Secretion Effector SrfJ: A Glucosylceramidase Affecting the Lipidome and the Transcriptome of Mammalian Host Cells
(MDPI, 2023-05-07)Type III secretion systems are found in many Gram-negative pathogens and symbionts of animals and plants. Salmonella enterica has two type III secretion systems associated with virulence, one involved in the invasion of ... -
Schwann cell and axon: An interlaced unit—From action potential to phenotype expression
(Facultad de Ciencias, 2016)Here we propose a model of a peripheral axon with a great deal of autonomy from its cell body-the autonomous axon-but with a substantial dependence on its ensheathing Schwann cell (SC), the axon-SC unit. We review evidence ... -
Schwann cell reprogramming into repair cells increases miRNA-21 expression in exosomes promoting axonal growth
(Company of Biologists Ltd, 2020-06)Functional recovery after peripheral nerve damage is dependent on the reprogramming of differentiated Schwann cells (dSCs) into repair Schwann cells (rSCs), which promotes axonal regeneration and tissue homeostasis. ... -
Senescent Schwann cells induced by aging and chronic denervation impair axonal regeneration following peripheral nerve injury
(Wiley-Blackwell, 2023-12-07)Following peripheral nerve injury, successful axonal growth and functional recovery require Schwann cell (SC) reprogramming into a reparative phenotype, a process dependent upon c-Jun transcription factor activation. ... -
Serine 25 phosphorylation inhibits RIPK1 kinase-dependent cell death in models of infection and inflammation
(NATURE PUBLISHING GROUP, 2019)RIPK1 regulates cell death and inflammation through kinase-dependent and -independent mechanisms. As a scaffold, RIPK1 inhibits caspase-8-dependent apoptosis and RIPK3/MLKL-dependent necroptosis. As a kinase, RIPK1 ... -
SK channel activation potentiates auranofin-induced cell death in glio- and neuroblastoma cells
(Elsevier Inc., 2020-01)Brain tumours are among the deadliest tumours being highly resistant to currently available therapies. The proliferative behaviour of gliomas is strongly influenced by ion channel activity. Small-conductance calcium-activated ... -
Teased Fiber Preparation of Myelinated Nerve Fibers from Peripheral Nerves for Vital Dye Staining and Immunofluorescence Analysis
(Humana Press, 2018)Glial cells regulate a wide variety of neuronal functions during physiological and pathological conditions. Therefore, the study of glial cells and their association with axons is of paramount importance in order to ... -
The Enigmatic Role of C9ORF72 in Autophagy
(FRONTIERS MEDIA SA, 2017-08-03)Amyotrophic lateral sclerosis (ALS) is a devastating neurodegenerative disease characterized by the loss of motor neurons resulting in a progressive and irreversible muscular paralysis. Advances in large-scale genetics and ... -
The inhibition of CTGF/CCN2 activity improves muscle and locomotor function in a murine ALS model
(OXFORD UNIV PRESS, 2018)Amyotrophic lateral sclerosis (ALS) is a devastating adult-onset progressive neurodegenerative disease characterized by upper and lower motoneuron degeneration. A total of 20% of familial ALS (fALS) cases are explained by ... -
The Mitochondrial Unfolded Protein Response: A Hinge Between Healthy and Pathological Aging
(Frontiers Media S.A., 2020-09)Aging is the time-dependent functional decline that increases the vulnerability to different forms of stress, constituting the major risk factor for the development of neurodegenerative diseases. Dysfunctional mitochondria ... -
The necroptosis machinery mediates axonal degeneration in a model of Parkinson disease
(NATURE PUBLISHING GROUP, 2020-04)Parkinson's disease (PD) is the second most common neurodegenerative condition, characterized by motor impairment due to the progressive degeneration of dopaminergic neurons in the substantia nigra and depletion of dopamine ... -
The necroptosis pathway and its role in age-related neurodegenerative diseases: will it open up new therapeutic avenues in the next decade?
(Taylor and Francis Ltd., 2020-07)Introduction: Necroptosis is a programmed form of necrotic cell death. Growing evidence demonstrates that necroptosis contributes to cell demise in different pathological conditions including age-dependent neurodegenerative ... -
The Oculome Panel Test: Next-Generation Sequencing to Diagnose a Diverse Range of Genetic Developmental Eye Disorders
(ELSEVIER SCIENCE INC, 2019)Purpose: To develop a comprehensive next-generation sequencing panel assay that screens genes known to cause developmental eye disorders and inherited eye disease and to evaluate its diagnostic yield in a pediatric cohort ... -
The Protein Tyrosine Phosphatase Receptor Delta Regulates Developmental Neurogenesis
(CELL PRESS, 2020)PTPRD is a receptor protein tyrosine phosphatase that is genetically associated with neurodevelopmental disorders. Here, we asked whether Ptprd mutations cause aberrant neural development by perturbing neurogenesis in the ... -
Tumor Microbiome Diversity and Composition Influence Pancreatic Cancer Outcomes
(CELL PRESS, 2019)Most patients diagnosed with resected pancreatic adenocarcinoma (PDAC) survive less than 5 years, but a minor subset survives longer. Here, we dissect the role of the tumor microbiota and the immune system in influencing ... -
