Changes in the fibrinolytic components of cultured human umbilical vein endothelial cells induced by endotoxin, tumor necrosis factor-alpha and interleukin-1alpha

open access: yesHaematologica, 1999
BACKGROUND AND OBJECTIVE: Vascular fibrinolysis, a major natural defense mechanism against thrombosis, is a highly regulated process. The aim of this study was to evaluate the effect of endotoxin, tumor necrosis factor-alpha (TNFalpha) and interleukin ...

Harnessing blood clot as a native scaffold for orchestrating tissue repairs and regeneration

open access: yesBMEMat, EarlyView.
The blood clot, owing to its dynamic composition and unique microenvironment, holds significant yet underappreciated potential for tissue engineering. This review systematically summarizes the pathophysiology of clot formation, the key regulatory factors shaping its microenvironment, and its applications in both pre‐clinical and clinical settings ...

Hybrid Macrocyclic Peptides — Synthetic Strategies to Diversify and Cyclize Peptide Libraries in Phage Display Selections

open access: yesChemistry – A European Journal, EarlyView.
Hybrid macrocyclic peptides unite genetically encoded peptide libraries with the structural complexity of synthetic small molecules. This Review critically analyzes phage‐compatible cyclization and diversification chemistries, highlights emerging opportunities beyond traditional cysteine‐based approaches, and outlines how future advances may enable the

Involvement of Urokinase-Type Plasminogen Activator in Acantholysis Induced by Pemphigus IgG [PDF]

open access: yes, 1987
Pemphigus IgG induces acantholysis in skin organ culture without the involvement of complement. Urokinase-type plasminogen activator, a proteolytic enzyme, has been implicated in the development of acantholysis.

Clinical Evidence for Correlation of Insufficient Tissue Oxygen Supply (Hypoxia) and Tumor-Associated Proteolysis in Squamous Cell Carcinoma of the Head and Neck

open access: yesThe International Journal of Biological Markers, 2000
Hypoxic tumors of patients with squamous cell carcinoma of the head and neck show a consistent trend towards poor treatment outcome. We now report that tumor hypoxia in these patients is correlated with elevated antigen content of the tumor-associated ...

Gut microbiota‐related modulation of immune mechanisms in post‐infarction remodelling and heart failure

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 942-954, April 2025.
Abstract The immune system has long been recognized as a key driver in the progression of heart failure (HF). However, clinical trials targeting immune effectors have consistently failed to improve patient outcome across different HF aetiologies. The activation of the immune system in HF is complex, involving a broad network of pro‐inflammatory and ...

Urokinase and type I plasminogen activator inhibitor production by normal human hepatocytes: modulation by inflammatory agents

open access: yes, 1994
We examined the effects of inflammatory cytokines (interleukin-1 beta, tumor necrosis factor-alpha and transforming growth factor-beta) on the plasminogen activator system (urokinase, tissue-type plasminogen activator, type 1 plasminogen activator ...

Causal correlations between inflammatory proteins and heart failure: A two‐sample Mendelian randomization analysis

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1374-1385, April 2025.
Abstract Aims Inflammation plays a critical role in both the development and progression of heart failure (HF), which is a leading cause of morbidity and mortality worldwide. However, the causality between specific inflammation‐related proteins and HF risk remains unclear.

Interdependence of kallikrein-related peptidases in proteolytic networks [PDF]

open access: yes, 2010
Human kallikrein-related peptidases (KLKs) are 15 homologous serine proteases involved in several (patho)physiological processes, including cancer. Secreted as precursors, they are activated upon proteolytic release of a short propeptide. We searched for

The structure of the urokinase-type plasminogen activator receptor gene [PDF]

open access: yesBlood, 1994
The cellular receptor for urokinase-type plasminogen activator (uPAR) is a glycosylphosphatidylinositol (GPI)-anchored membrane protein that plays a central role in pericellular plasminogen activation. It contains 313 amino acid residues, including 28 cysteine residues in a pattern of three homologous repeats. The cysteine residue pattern suggests that
