A dysregulated immune response is associated with an excessive release of cytokines that can lead to systemic vasoplegia and vasoplegic shock with the development of multiorgan failure that is associated with an increased risk of dying. Under physiological circumstances, the endothelium and the glycocalyx are responsible for maintaining vascular tone, capillary permeability, and hemostasis, and controlling inflammation. In hyperinflammation, the endothelium and glycocalyx become damaged due to the excessive production of certain toxic proteins, along with an overwhelming release of cytokines. It has been shown in both in vitro animal experiments and in humans that extracorporeal hemoadsorption can reduce circulating levels of cytokines and may also remove toxic proteins that directly take part in endothelium and glycocalyx damage. The current review aims to summarize current knowledge, put recent findings into context, and introduce the hypothesis of "endothelial protection with hemoadsorption" in critically ill patients.

Chronic kidney disease (CKD) substantially increases cardiovascular risk, with endothelial dysfunction as its central pathological mechanism. This review summarises the molecular regulatory mechanisms underlying endothelial dysfunction in CKD and highlights recent advances in treatment strategies. The pathophysiology of endothelial injuries involves a complex network of multiple factors and mechanisms, including oxidative stress, inflammation, glycocalyx damage, ischaemia, hypoxia, cellular senescence and endothelial-mesenchymal transition (EndMT).

Despite the use of targeted drugs for human epidermal growth factor receptor type 2 (HER2)-positive salivary duct carcinoma (SDC) treatment, the overall prognosis for SDC remains poor. In this study, we aimed to investigate whether the glycocalyx of SDC cells serves as a potential cell surface marker. To understand the complex structure of the glycocalyx of salivary gland tumors, we used a lectin with glycan-specific binding properties.

The progress of transcatheter valve replacement has significantly reduced the risk of valve replacement, increasing the demand for bioprosthetic heart valves (BHVs). Currently, the defects of BHVs, including thrombosis, poor endothelialization, calcification, and immune responses that are associated with glutaraldehyde crosslinking and their xenogeneic collagenous matrix, have accelerated the degeneration of BHVs. Herein, we constructed an endothelial function biomimetic hydrogel surface engineered non-glutaraldehyde BHV based on bioinspired catechol-crosslinking system and metal-chelation.

The endothelial glycocalyx is a gel-like structure on the endothelium that plays a critical role in vasculature. We have shown that 12 wk of a Western diet (WD) increases glycocalyx thickness and integrity. However, the time course and contributors to these adaptations are unknown.

Objective: To explore the protective effect of glycosaminoglycans (GAG) on vascular endothelium in patients with sepsis.
Methods: A prospective study was conducted on adult patients with sepsis admitted to the intensive care unit (ICU) of Hangzhou Normal University Affiliated Hospital from December 2022 to December 2023. Patients were randomly divided into conventional treatment group and GAG intervention group.
