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 ...

The urokinase receptor as an entertainer of signal transduction

open access: yesFrontiers in Bioscience, 2009
The serine-protease urokinase (uPA) and its specific membrane receptor uPAR controls matrix degradation through the conversion of plasminogen into plasmin and play a crucial role in a number of biological processes including local fibrinolysis, inflammation, angiogenesis, matrix remodelling during wound healing, tumor invasion and metastasis.

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 ...

Participation of the urokinase receptor in neutrophil efferocytosis

open access: yesBlood, 2009
AbstractThe urokinase receptor (uPAR) plays an important role in regulation of fibronolysis, cell migration, and adhesion. In this study, we examined whether uPAR plays a role in modulating efferocytosis of neutrophils. Macrophages from uPAR−/− mice demonstrated enhanced ability to engulf viable wild-type (WT) neutrophils in vitro and in vivo in the ...

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.

Urokinase–urokinase receptor interaction mediates an inhibitory signal for HIV-1 replication [PDF]

open access: yesProceedings of the National Academy of Sciences, 2002
Elevated levels of soluble urokinase-type plasminogen activator (uPA) receptor, CD87/u-PAR, predict survival in individuals infected with HIV-1. Here, we report that pro-uPA (or uPA) inhibits HIV-1 expression in U937-derived chronically infected promonocytic U1 cells stimulated with phorbol 12-myristate 13-acetate (PMA) or tumor necrosis factor-α (TNF ...

Urokinase Plasminogen Activator

open access: yes, 2016
The urokinase plasminogen activator system (uPAS) is an essential mechanism in a wide variety of biological processes such as fibrinoloysis, inflammation, atherosclerotic plaque formation, matrix remodeling during wound healing, tumor invasion ...

WONOEP XVII appraisal: The role of the extracellular matrix in epilepsy

open access: yesEpilepsia, EarlyView.
Abstract The extracellular matrix (ECM) is composed of proteoglycans and glycoproteins that regulate the external environment surrounding neurons, glia, and the vascular system. The ECM is vital for maintaining the structure and function of the brain and also acts as a reservoir for various signaling molecules and neurotransmitters, modulating synaptic

Urokinase receptor mediates mechanical force transfer across the cell surface

open access: yes, 1995
The tripartite complex formed by the urokinase receptor, urokinase, and its inhibitor is an enzymatic system that controls plasmin formation involved in degradation of extracellular matrix proteins.

PAI‐1 inhibits urokinase‐induced chemotaxis by internalizing the urokinase receptor

open access: yesFEBS Letters, 2001
PAI‐1 (plasminogen activator inhibitor‐1) binds the urokinase‐type plasminogen activator (uPA) and causes its degradation via its receptor uPAR and low‐density lipoprotein receptor‐related protein (LRP). While both uPA and PAI‐1 are chemoattractants, we find that a preformed uPA–PAI‐1 complex has no chemotactic activity and that PAI‐1 inhibits uPA ...
