Targeted capillary photothrombosis via multiphoton excitation of Rose Bengal

Microvascular stalling, the process occurring when a capillary temporarily loses perfusion, has gained increasing interest in recent years through its demonstrated presence in various neuropathologies. Studying the impact of such stalls on the surrounding ...

Type I IFNs link skin-associated dysbiotic commensal bacteria to pathogenic inflammation and angiogenesis in rosacea

Alessio Mylonas, Yichen Wang, Jiaqi Chen

Rosacea is a common chronic inflammatory skin disease with a fluctuating course of excessive inflammation and apparent neovascularization. Microbial dysbiosis with a high density of Bacillus oleronius and increased activity of kallikrein 5, which cleaves c ...

Sodium thiosulfate, a source of hydrogen sulfide, stimulates endothelial cell proliferation and neovascularization

Georges Wagnières, Jaroslava Joniová, Séverine Marguerite Urfer

Therapies to accelerate vascular repair are currently lacking. Pre-clinical studies suggest that hydrogen sulfide (H2S), an endogenous gasotransmitter, promotes angiogenesis. Here, we hypothesized that sodium thiosulfate (STS), a clinically relevant source ...

The cGAS–STING pathway drives type I IFN immunopathology in COVID-19

Andrea Ablasser, Muhammet Fatih Gülen, Vivek Vijay Thacker, Théo Nass, Martin Schaller, Kunal Sharma

COVID-19, which is caused by infection with SARS-CoV-2, is characterized by lung pathology and extrapulmonary complications1,2. Type I interferons (IFNs) have an essential role in the pathogenesis of COVID-19 (refs 3–5). Although rapid induction of type I ...

A Tead1-Apelin axis directs paracrine communication from myogenic to endothelial cells in skeletal muscle

Bart Deplancke, Julie Marie Russeil, Sonia Karaz, Maria Deak, Umji Lee, Benjamin D. Cosgrove

Apelin (Apln) is a myokine that regulates skeletal muscle plasticity and meta-bolism and declines during aging. Through a yeast one-hybrid transcription factor binding screen, we identified the TEA domain transcription factor 1 (Tead1) as a novel regulator ...

FOXC2 controls adult lymphatic endothelial specialization, function, and gut lymphatic barrier preventing multiorgan failure

Mauro Delorenzi, Alexis Rapin, Dominique Velin, Esther Bovay, François Renevey

The mechanisms maintaining adult lymphatic vascular specialization throughout life and their role in coordinating inter-organ communication to sustain homeostasis remain elusive. We report that inactivation of the mechanosensitive transcription factor Foxc ...

The angiopoietin-Tie2 pathway regulates Purkinje cell dendritic morphogenesis in a cell-autonomous manner

Michele De Palma

Neuro-vascular communication is essential to synchronize central nervous system development. Here, we identify angiopoietin/Tie2 as a neuro-vascular signaling axis involved in regulating dendritic morphogenesis of Purkinje cells (PCs). We show that in the ...

Considerations for analysis of endothelial shear stress and strain in FSI models of atherosclerosis

Lydia Aslanidou, Fotios Savvopoulos

Atherosclerosis is a lipid driven chronic inflammatory disease that is characterized by the formation of plaques at predilection sites. These predilection sites (side branches, curved segments, and bifurcations) have often been associated with disturbed sh ...

CO-REGULATION OF ENDOTHELIAL AND MYOGENIC CELL FATES THROUGH INTERCELLULAR CROSSTALK IN SKELETAL MUSCLE

Umji Lee

Skeletal muscle is one of the most dynamic organs in the human body, which has a vigorous potential to regenerate and adapt to environmental changes. Depending on environments, skeletal muscle enables essential life activities to survive by controlling mov ...

Mitochondrial Deacetylase Sirt3 Reduces Vascular Dysfunction and Hypertension While Sirt3 Depletion in Essential Hypertension Is Linked to Vascular Inflammation and Oxidative Stress

Johan Auwerx

Rationale: Hypertension represents a major risk factor for stroke, myocardial infarction, and heart failure and affects 30% of the adult population. Mitochondrial dysfunction contributes to hypertension, but specific mechanisms are unclear. The mitochondri ...
