Molecules from unique species similar in structure and function to human skin molecules
Scientists from the ARC Centre of Excellence for Electromaterial Science (ACES) and University of Wollongong (UOW), in partnership with their seaweed bioinks collaborators Venus Shell Systems, have discovered that a molecular species known as ulvan aids wound healing in humans.
Their research paper is the cover story on the latest issue of Biomaterials Science. Titled ‘3D bioprinting dermal-like structures using species-specific ulvan’, the new findings outline how ulvan contained in green seaweed can play a key role in wound healing with its structure resembling the biomolecules found in humans.

Protein misfolding contributes to the pathogenesis of SCA3
Proteins play a significant role in every single cell development in the human body, including neurons. Numerous studies have proved that misfolds and aggregation of proteins contribute to many occurrences of human diseases. Proteins need to adopt proper folding and architecture before being able to execute their biological functions. Even a minor improper assembly of a protein may result in cellular malfunctioning, leading to toxic insoluble protein aggregates that cause diseases. Progressive misfolding of proteins and aggregates will interfere with the functionalities of other normal proteins, and these are also detected in the deteriorating neurons of SCA3 and other protein misfolding induced disorders, including polyglutamine (polyQ) diseases.
