Myelin is an electrical insulator that enables saltatory nerve conduction and is essential for proper functioning of the central nervous system (CNS). It is formed by oligodendrocytes (OLs) in the CNS, and during OL development various molecules, including extracellular matrix (ECM) proteins, regulate OL differentiation and myelination; however, the role of ECM proteins in these processes is not well understood. Our present work is centered on the analyses of the expression and function of fibulin-7 (Fbln7), an ECM protein of the fibulin family, in OL differentiation.

Purpose Of Review: This review aims to examine recent advances in the understanding of injury-induced endotheliopathy and therapeutics to mitigate its development in critically injured patients.
Recent Findings: Clinical studies have clearly demonstrated that syndecan-1 ectodomains can be found in circulation after various types of trauma and injury and correlates with worse outcomes. As the mechanisms of endotheliopathy are better understood, pathologic hyperadhesive forms of von Willebrand factor, along with a relative deficiency of its cleaving enzyme, a disintegrin and metalloprotease with thrombospondin type I motifs, member 13 (ADAMTS13), have emerged as additional biomarkers.

Peptide-based therapeutics are gaining attention for their potential to target various viral and host cell factors. One notable example is Pep19-2.5 (Aspidasept), a synthetic anti-lipopolysaccharide peptide that binds to heparan sulfate proteoglycans (HSPGs) and has demonstrated inhibitory effects against certain bacteria and enveloped viruses.

Adeno-associated virus (AAV)-based vectors have emerged as an effective and widely used technology for somatic gene therapy approaches, including those targeting the retina. A major advantage of the AAV technology is the availability of a large number of serotypes that have either been isolated from nature or produced in the laboratory. These serotypes have different properties in terms of sensitivity to neutralizing antibodies, cellular transduction profile and efficiency.

Vesicle trafficking is pivotal in heparan sulfate (HS) biosynthesis, influencing its spatial and temporal regulation within distinct Golgi compartments. This regulation modulates the sulfation pattern of HS, which is crucial for governing various biological processes. Here, we investigate the effects of silencing Rab1A and Rab2A expression on the localisation of 3-O-sulfotransferase-5 (3OST5) within Golgi compartments and subsequent alterations in HS structure and levels.
