[HTML][HTML] Drosophila ßHeavy-Spectrin is required in polarized ensheathing glia that form a diffusion-barrier around the neuropil

N Pogodalla, H Kranenburg, S Rey… - Nature …, 2021 - nature.com
In the central nervous system (CNS), functional tasks are often allocated to distinct
compartments. This is also evident in the Drosophila CNS where synapses and dendrites …

A postsynaptic Spectrin scaffold defines active zone size, spacing, and efficacy at the Drosophila neuromuscular junction

J Pielage, RD Fetter, GW Davis - The Journal of cell biology, 2006 - rupress.org
Synaptic connections are established with characteristic, cell type–specific size and spacing.
In this study, we document a role for the postsynaptic Spectrin skeleton in this process. We …

Drosophila βHeavy-spectrin is essential for development and contributes to specific cell fates in the eye

Apical Spectrin Is Essential for Epithelial Morphogenesis but Not Apicobasal Polarity in Drosophila

DC Zarnescu, CM Thomas - The Journal of cell biology, 1999 - rupress.org
Changes in cell shape and position drive morphogenesis in epithelia and depend on the
polarized nature of its constituent cells. The spectrin-based membrane skeleton is thought to …

βHeavy-spectrin has a restricted tissue and subcellular distribution during Drosophila embryogenesis

CM Thomas, DP Kiehart - Development, 1994 - journals.biologists.com
The components of the membrane skeleton play an important role in maintaining membrane
structure during the dynamic changes in cell shape that characterize development. βHeavy …

Drosophila α-and β-spectrin mutations disrupt presynaptic neurotransmitter release

The C-terminal domain of Drosophila βHeavy-spectrin exhibits autonomous membrane association and modulates membrane area

JA Williams, B MacIver, EA Klipfell… - Journal of Cell …, 2004 - journals.biologists.com
Current models of cell polarity invoke asymmetric cues that reorganize the secretory
apparatus to induce polarized protein delivery. An important step in this process is the …

Astrocytes require perineuronal nets to maintain synaptic homeostasis in mice

BP Tewari, ALM Woo, CE Prim, L Chaunsali… - Nature …, 2024 - nature.com
Perineuronal nets (PNNs) are densely packed extracellular matrices that cover the cell body
of fast-spiking inhibitory neurons. PNNs stabilize synapses inhibiting synaptic plasticity …

[HTML][HTML] Localized netrins act as positional cues to control layer-specific targeting of photoreceptor axons in Drosophila

K Timofeev, W Joly, D Hadjieconomou, I Salecker - Neuron, 2012 - cell.com
A shared feature of many neural circuits is their organization into synaptic layers. However,
the mechanisms that direct neurites to distinct layers remain poorly understood. We …

Multiple interactions control synaptic layer specificity in the Drosophila visual system

MY Pecot, W Tadros, A Nern, M Bader, Y Chen… - Neuron, 2013 - cell.com
How neurons form synapses within specific layers remains poorly understood. In the
Drosophila medulla, neurons target to discrete layers in a precise fashion. Here we …
