The axonal endoplasmic reticulum: one organelle many functions in development, maintenance, and plasticity
(Wiley, 2018)
The endoplasmic reticulum (ER) is highly conserved in eukaryotes and neurons. Indeed, the localization of the organelle in axons has been known for nearly half a century. However, the relevance of the axonal ER is only ...
Global and local mechanisms sustain axonal proteostasis of transmembrane proteins
(Blackwell Munksgaard, 2017)
© 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd The control of neuronal protein homeostasis or cursive is tightly regulated both spatially and temporally, assuring accurate and integrated responses to ...
Origin of axonal proteins: Is the axon-schwann cell unit a functional syncytium?
(2016)
The structural homeostasis is challenging for neurons, whose axons extend up to meters in large animals, and the axoplasmic mass reaches over a thousand times that of the cell body. Thus, the protein demand may overcome ...
Dynamical speckles patterns of action potential transmission effects in squid giant axon membrane.
(Porto, 2013)
Undoubtedly the most important result of the investigations in physiology and biophysics was the discovery of the electrochemical mechanism of propagation of the action potential in nerves that was made by Hodgkin and ...
New insights on epigenetic mechanisms supporting axonal development: Histone marks and miRNAs
(Wiley Blackwell Publishing, Inc, 2020-12)
Mechanisms supporting axon growth and the establishment of neuronal polarity have remained largely disconnected from their genetic and epigenetic fundamentals. Recently, post-transcriptional modifications of histones ...
Origin of axonal proteins: Is the axon-schwann cell unit a functional syncytium?
(CIENCIAS, 2016)
The structural homeostasis is challenging for neurons, whose axons extend up to meters in large animals, and the axoplasmic mass reaches over a thousand times that of the cell body. Thus, the protein demand may overcome ...
Extracellular matrix stiffness negatively affects axon elongation, growth cone area and F-actin levels in a collagen type I 3D culture
(John Wiley & Sons Ltd, 2021-11)
Three dimensional (3D) in vitro neuronal cultures can better reproduce physiologically relevant phenotypes compared to 2D-cultures, because in vivo neurons reside in a 3D microenvironment. Interest in neuronal 3D cultures ...
Exchange Protein Directly Activated by cAMP (EPAC) Regulates Neuronal Polarization through Rap1B
(Soc. Neuroscience, 2015)
Acquisition of neuronal polarity is a complex process involving cellular and molecular events. The second messenger cAMP is involved in axonal specification through activation of protein kinase A. However, an alternative ...
Physiopathology of traumatic brain injury.
(2012-11-30)
Introducción: El trauma craneoencefálico (TCE) es un problema de salud mundial que produce incapacidades motoras,
del comportamiento o en la esfera cognitiva.
Objetivo: Hacer una revisión de la fisiopatología del TCE ...
