Perivascular Matrix Densification Dysregulates Angiogenesis and Activates Pro‐Inflammatory Endothelial Cells

Advanced Science, EarlyView.
Perivascular matrix densification promotes the emergence of aberrant endothelial tip cells (ATECs) that invade and persist within fibrotic microenvironments. Using in vivo lineage tracing and a human microvessel model, this study shows that fibrous matrix cues destabilize VE‐cadherin–mediated junctions to gate TGF‐β signaling, inducing a pro ...

PPARs: Nuclear Receptors Controlled by, and Controlling, Nutrient Handling through Nuclear and Cytosolic Signaling

PPAR Research, 2010
Peroxisome proliferator-activated receptors (PPARs), which are known to regulate lipid homeostasis, are tightly controlled by nutrient availability, and they control nutrient handling.

Upregulation of ERK1/2-eNOS via AT2 receptors decreases the contractile response to angiotensin II in resistance mesenteric arteries from obese rats. [PDF]

PLoS ONE, 2014
It has been clearly established that mitogen-activated protein kinases (MAPKS) are important mediators of angiotensin II (Ang II) signaling via AT1 receptors in the vasculature.

Characterization of the mitogen regulated protein receptor

, 2018
Mitogen regulated protein (MRP; also called proliferin) is a 34 IcDa glycoprotein secreted during murine gestation. Its temporal profile of synthesis and secretion and its homology to prolactin indicate an hormonal role in fetal development. To identify its target tissues in 125 vivo, we injected tracer amounts of I-labeled MRP into nonpregnant mice ...

A 3D Human Bone and Bone Marrow‐on‐a‐Chip Model for In Vitro Bone Remodeling and Immune Cell Maintenance

Advanced Science, EarlyView.
This study presents a human Bone (and Bone Marrow)‐on‐a‐Chip model based on native human bone scaffolds and autologous cells. Dynamic perfusion and sequential cell seeding replicate the physiological bone remodeling process in vitro, enabling the long‐term culture of functional, mature bone marrow immune subpopulations.

Bilateral Subretinal Fluid Accumulation during Erdafitinib Therapy

TNOA Journal of Ophthalmic Science and Research
Fibroblast growth factor receptor (FGFR) plays a major role in maintaining retinal pigment epithelium cells. Drugs that inhibit the FGFR pathway block the activation of the mitogen-activated protein kinase pathway, leading to the synthesis of ...

IL‐7R‐Enriched Extracellular Vesicles From the Thymus Drive Colitis via Promoting Neutrophil Extracellular Trap Formation

Advanced Science, EarlyView.
Inflammatory bowel disease (IBD) pathogenesis remains unclear. This study reveals that thymus‐originated IL‐7R‐enriched extracellular vesicles exacerbate colitis by promoting neutrophil extracellular traps via a thymus‐gut axis, uncovering an inter‐organ communication mechanism in inflammatory bowel disease pathogenesis.

Synthetic Toll‐Like Receptors for Control of Innate Immunity With Far‐Red Light

Advanced Science, EarlyView.
Synthetic Toll‐like receptors (TLRs) are engineered by replacing their natural sensing regions with a far‐red‐light‐responsive module from a bacterial phytochrome. These synthetic receptors enable light‐controlled regulation of immune signaling in mammalian cells.

Subverting Toll-like receptor signalling by bacterial pathogens

Frontiers in Immunology, 2015
Pathogenic bacteria are detected by pattern-recognition receptors (PRRs) expressed on innate immune cells, which activate intracellular signal transduction pathways to elicit an immune response.

Mitogenic activity of neurotransmitter receptors

, 2000
Although the first evidence of the dopamine receptor-regulated proliferation of the pituitary prolactin-secreting cells was published in mid-seventies (Loyd et al. (1975) Nature 255: 497), its conceptual significance had remained overlooked for almost two decades.
