About this plugin

This Napari plugin was designed for the detection and quantification of periodic biological structures. As this plugin has not been uploaded to napari-hub as of this moment it cannot be installed on a pre-compiled, bundled version of Napari. Therefore Napari will need to be installed as a python package (more info about Napari installation). Further information about the installation and licensing of the plugin can be found below.

Guide

Actin is the most abundant protein in eukaryotic cells. As it is part of the cytoskeleton its function is essential for the maintenance of the cell's morphological structure. In neurons, it was only recently that researchers started paying attention to the peculiar subcellular organization and localization of actin. First focussing on the dendritic spines, later expanding to the axon.

The axon initial segment (AIS) is defined as the most proximal 30-60 µm of the axon and is known for its sturdy actin-betaIV cytoskeletal structure which is known to facilitate the densely packed ion channels, regulatory and scaffolding proteins on the membrane. The recent popularity of superresolution microscopy techniques like STORM and STED has made the study of the localization of these proteins relatively easy and straightforward.

 

 

Because of this property of the AIS many ion channels are localized either perpendicular to the actin rings or attached to a scaffolding protein called Ankyrin G which is localized in between two actin rings. This results in ion channels like the Kv 1.1 (displayed below) appearing similar to superresolution images of actin.

 

Example image of a rat hippocampal neuron AIS immunostained for Kv1.1. Image made on a Zeiss AxioImager Z1 equipped with a STEDYCON scanhead detector for confocal and super-resolution imaging, fitted with 4 APDs. Post-acquisition, image was deconvolved using Huygens Deconvolution Software

 

This plugin was designed to detect and quantify the distance and the goodness of periodicity between cellular periodic structures. Additionally, it can be used to detect and quantify the periodicity shift between two periodic stuctures.
