Age ‐dependent expression of Nav1.9 channels in medial prefrontal cortex pyramidal neurons in rats
ABSTRACT Developmental changes that occur in the prefrontal cortex during adolescence alter behavior. These behavioral alterations likely stem from changes in prefrontal cortex neuronal activity, which may depend on the properties and expression of ion channels. Nav1.9 sodium channels conduct a Na+ current that is TTX resistant with a low threshold and noninactivating over time. The purpose of this study was to assess the presence of Nav1.9 channels in medial prefrontal cortex (mPFC) layer II and V pyramidal neurons in young (20‐day old), late adolescent (60‐day old), and adult (6‐ to 7‐month old) rats. First, we d...

The where, what, and when of membrane protein degradation in neurons
ABSTRACT Membrane protein turnover and degradation are required for the function and health of all cells. Neurons may live for the entire lifetime of an organism and are highly polarized cells with spatially segregated axonal and dendritic compartments. Both longevity and morphological complexity represent challenges for regulated membrane protein degradation. To investigate how neurons cope with these challenges, an increasing number of recent studies investigated local, cargo‐specific protein sorting, and degradation at axon terminals and in dendritic processes. In this review, we explore the current answers to the ens...

Widespread transcriptional alternations in oligodendrocytes in the adult mouse brain following chronic stress
ABSTRACT Emerging evidence shows that oligodendrogenesis and myelination are highly responsive to behavioral experience, including physical activity and social experience. This form of myelin plasticity is being increasingly appreciated and examined in the prefrontal cortex (PFC), a critical brain region involved in complex emotional and cognitive behavior. However, it remains unclear whether myelination in other brain regions is affected by behavioral experience. Here we report that exposure to 4 weeks of chronic variable stress induced anxiety‐ and depressive‐like behavior in male adult mice. In concert with these be...

Intrinsic and adaptive myelination —A sequential mechanism for smart wiring in the brain
ABSTRACT The concept of adaptive myelination—myelin plasticity regulated by activity—is an important advance for the field. What signals set up the adaptable pattern in the first place? Here we review work that demonstrates an intrinsic pathway within oligodendrocytes requiring only an axon‐shaped substrate to generate multilayered and compacted myelin sheaths of a physiological length. Based on this, we discuss a model we proposed in 2015 which argues that myelination has two phases—intrinsic and then adaptive—which together generate “smart wiring,” in which active axons become more myelinated. This model ex...

To mdivi ‐1 or not to mdivi‐1: Is that the question?
This study raises serious issues regarding the interpretation of data addressing the effects of mdivi‐1 as reflective of the inhibition of Drp1 and thus fission. This commentary considers the evidence for and against mdivi‐1 as an inhibitor of Drp1 and presents the following considerations; (1) the activity of mdivi‐1 toward Drp1 GTPase activity requires further biochemical investigation, (2) as there is a large body of literature using mdivi‐1 in vitro with effects as predicted for inhibition of Drp1 and mitochondrial fission, reviewed herein, the evidence is in favor of mdivi‐1's originally described bioactivit...
