Revised Cornechiniscus (Heterotardigrada) and new phylogenetic analyses negate echiniscid subfamilies and tribes [PDF]

open access: yesRoyal Society Open Science, 2020
Echiniscidae are undoubtedly the most thoroughly studied lineage of the class Heterotardigrada. Recently, new subfamilies and tribes grouping echiniscid genera based on traditionally recognized morphological clues have been proposed. Here, by integrative

Facile and Efficient Enzymatic Methods for Harvesting or Removal of Cuticle Cells from Human Hair Shafts

open access: yesJournal of Natural Fibers, 2022
Human hair fibers are structurally organized as a cortex protected by an outer scaly sheath (cuticle). Developing methods to isolate these two compartments will help to elucidate their roles in hair biology and develop potential applications.

Properties, Genetics and Innate Immune Function of the Cuticle in Egg-Laying Species

open access: yesFrontiers in Immunology, 2022
Cleidoic eggs possess very efficient and orchestrated systems to protect the embryo from external microbes until hatch. The cuticle is a proteinaceous layer on the shell surface in many bird and some reptile species.

Retroactive maintains cuticle integrity by promoting the trafficking of Knickkopf into the procuticle of Tribolium castaneum. [PDF]

open access: yesPLoS Genetics, 2013
Molting, or the replacement of the old exoskeleton with a new cuticle, is a complex developmental process that all insects must undergo to allow unhindered growth and development.

The tardigrade cuticle

open access: yesLimnological Review, 2021
Abstract Tardigrades (phylum Tardigrada) are aquatic microecdysozoans that have adapted to survive extreme conditions through the formation of cysts or ametabolic tuns. Their body is covered by a cuticle that plays an important role in their life cycle, including their response and adaptation to environmental challenges.

Changes in cuticle structure during growth in two terrestrial isopods (Crustacea: Isopoda: Oniscidea)

open access: yesNauplius, 2020
Terrestrial isopods are a successful group of terrestrial crustaceans. Their exoskeletal cuticle has been studied in several species. However, it is not known whether the cuticle of these animals becomes thicker or how its structure changes as the ...

Nanoscale patterning of collagens in C. elegans apical extracellular matrix

open access: yesNature Communications, 2023
Apical extracellular matrices (aECMs) are complex extracellular compartments that form important interfaces between animals and their environment. In the adult C.

The plant cuticle

open access: yesCurrent Biology, 2023
The plant cuticle is one of the key innovations that allowed plants to colonize terrestrial ecosystems. By limiting molecular diffusion, the cuticle provides an interface that ensures controlled interactions between plant surfaces and their environments.

A conserved metalloprotease mediates ecdysis in Caenorhabditis elegans [PDF]

open access: yes, 2004
Molting is required for progression between larval stages in the life cycle of nematodes. We have identified four mutant alleles of a <i>Caenorhabditis elegans</i> metalloprotease gene, <i>nas-37</i>, that cause incomplete ...

Combined extracellular matrix cross-linking activity of the peroxidase MLT-7 and the dual oxidase BLI-3 is critical for post-embryonic viability in Caenorhabditis elegans [PDF]

open access: yes, 2009
The nematode cuticle is a protective collagenous extracellular matrix that is modified, cross-linked, and processed by a number of key enzymes. This Ecdysozoan-specific structure is synthesized repeatedly and allows growth and development in a linked ...
