Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

open access: yesFEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

Specific structural features of syndecans and heparan sulfate chains are needed for cell signaling [PDF]

open access: yesBrazilian Journal of Medical and Biological Research, 2006
The syndecans, heparan sulfate proteoglycans, are abundant molecules associated with the cell surface and extracellular matrix and consist of a protein core to which heparan sulfate chains are covalently attached. Each of the syndecan core proteins has a

The Enzymatic Degradation of Heparan Sulfate [PDF]

open access: yesProtein & Peptide Letters, 2017
Glycosaminoglycans (GAGs) such as heparan sulfate (HS) interact with a number of factors in the extracellular matrix (ECM) and as a consequence play a key role in the metabolic processes occurring within the cell. The dynamic synthesis and degradation of HS (and all GAGs) are necessary for ensuring that optimal chains are present for these functions ...

Characterization of PmHS2 glycosyltransferases for the controlled synthesis of heparosan : a precursor of heparin and heparan sulfate [PDF]

open access: yes, 2011
Heparin (Hep), a highly sulfated and complex glycosaminoglycan polysaccharides, is worldwide used as an anticoagulant compound to prevent blood clotting during surgery.

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation

open access: yesFEBS Letters, EarlyView.
Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...

Endothelial Heparan Sulfate in Angiogenesis [PDF]

open access: yes, 2010
Heparan sulfate (HS) is a linear polysaccharide composed of 50-200 glucosamine and uronic acid (glucuronic acid or iduronic acid) disaccharide repeats with epimerization and various sulfation modifications. HS is covalently attached to core proteins to form HS-proteoglycans.

Patient‐Derived 3D Heart‐On‐a‐Chip Model of Dilated Cardiomyopathy With Embedded Bead‐Based Mapping of Tissue Contractility

open access: yesAdvanced Healthcare Materials, EarlyView.
A heart‐on‐a‐chip model of dilated cardiomyopathy is developed from patient‐derived induced pluripotent stem cells. The model recapitulates key disease phenotypes and enables functional assessment through integrated bead‐based tracking and pillar deflection measurements.

Expression Pattern of Sulf1 and Sulf2 in Chicken Tissues and Characterization of Their Expression During Different Periods in Skeletal Muscle Satellite Cells [PDF]

open access: yesBrazilian Journal of Poultry Science
Heparan sulfate proteoglycans (HSPGs) are present on the cell surface and in the extracellular matrix in all metazoans. HSPGs interact with growth factors and receptors through heparan sulfate (HS) chains.

Agrin Is a Heparan Sulfate Proteoglycan [PDF]

open access: yesJournal of Biological Chemistry, 1995
In the present study we have identified the extracellular matrix protein agrin as a major heparan sulfate proteoglycan (HSPG) in embryonic chick brain. Using monoclonal antibodies and a polyclonal antiserum to the core protein of a previously identified HSPG from embryonic chick brain, our expression screened a random-primed E9 chick brain cDNA library.

Automated Platform for the Synthesis of Heparan Sulfate Oligosaccharide Libraries for Decoding Glycosaminoglycan-Protein Interactions [PDF]

open access: yes, 2022
Glycosaminoglycans (GAGs) are abundant, ubiquitous carbohydrates in biology, yet their structural complexity has limited an understanding of their biological roles and structure-function relationships.
