Estimating the synaptic current in a multi-conductance AMPA receptor model [PDF]

, 2010
A pre-synaptic neuron releases diffusing neurotransmitters such as glutamate that activate post-synaptic receptors. The amplitude of the post-synaptic current, mostly mediated by glutamatergic (AMPARs) receptors, is a fundamental signal that may generate an action potential.

Aberrant expression of receptors for platelet-derived growth factor in an anaplastic thyroid carcinoma cell line.

Proceedings of the National Academy of Sciences of the United States of America, 1988
Receptors for platelet-derived growth factor (PDGF) have previously only been found on cells of mesenchymal and glial origin. This study shows PDGF receptors on an anaplastic thyroid carcinoma cell line, C 643, that was found to express thyroglobulin ...

Organoid‐Like Neurovascular Spheroids Promote the Recovery of Hypoxic‐Ischemic Skin Flaps Through the Activation of Autophagy

Advanced Healthcare Materials, EarlyView.
Highly sprouting organoid‐like neurovascular spheroids (NVUs) are developed, featuring cell‐loaded poly‐3‐hydroxybutyrate 4‐hydroxybutyrate(P34HB) porous microsphere cores embedded within Gelatin Methacryloyl. NVUs formed complex vascular plexuses and secreted extracellular matrix in vitro, simulating autologous nerves and blood interaction.

Dovitinib preferentially targets endothelial cells rather than cancer cells for the inhibition of hepatocellular carcinoma growth and metastasis

Journal of Translational Medicine, 2012
Background Dovitinib is a receptor tyrosine kinase (RTK) inhibitor targeting vascular endothelial growth factor receptors, fibroblast growth factor receptors and platelet-derived growth factor receptor β. Dovitinib is currently in clinical trials for the

Preliminary study on electrophysiological changes after cellular autograft in age-related macular degeneration [PDF]

, 2014
Background: Evolving atrophic macular degeneration represents at least 80% of all macular degenerations and is currently without a standardized care. Autologous fat transplantation (AFT) efficacy was demonstrated by several studies, since these cells are

Influence of Hypoxia on a Biomaterial Model of the Bone Marrow Perivascular Niche

Advanced Healthcare Materials, EarlyView.
Hypoxia is a key factor in bone marrow physiology and hematopoietic stem cell behavior. Lower oxygen tension influences the secretion of vasculature‐derived hematopoietic regulatory factors and alters hematopoietic cell behavior in a conditioned medium hydrogel model of bone marrow. Cyclosporin A is used to mitigate normoxic stress during hematopoietic

Integrin-linked kinase functions as a downstream signal of platelet-derived growth factor to regulate actin polymerization and vascular smooth muscle cell migration

BMC Cell Biology, 2010
Background Vascular smooth muscle cell migration and accumulation in response to growth factors extensively contribute to the development of intimal thickening within the vessel wall.

Stochastic models of the binding kinetics of VEGF-A to VEGFR1 and VEGFR2 in endothelial cells [PDF]

arXiv, 2016
Vascular endothelial growth factor receptors (VEGFRs) are receptor tyrosine kinases (RTKs) that regulate proliferation, migration, angiogenesis and vascular permeability of endothelial cells. VEGFR1 and VEGFR2 bind vascular endothelial growth factors (VEGFs), inducing receptor dimerisation and activation, characterised by phosphorylation of tyrosine ...

Microvesicles and exosomes: new players in metabolic and cardiovascular disease [PDF]

, 2016
The past decade has witnessed an exponential increase in the number of publications referring to extracellular vesicles (EVs). For many years considered to be extracellular debris, EVs are now seen as novel mediators of endocrine signalling via cell-to ...
