Background Platelet derived growth factor is integral to maintenance of blood brain barrier, increases in response to blood brain barrier disruption, and may reflect neuroinflammation. Based on previous reports of better outcomes with dopaminergic antidepressants in depressed patients with elevated inflammatory biomarkers, we hypothesize that elevated peripheral platelet derived growth factor l...

BACKGROUND AND OBJECTIVE Platelet-derived growth factor-BB is a potent mediator of tooth-supporting periodontal tissue repair and regeneration. A limitation of the effects of topical platelet-derived growth factor-BB application is its short half-life in vivo. Gene therapy has shown strong promise for the long-term delivery of platelet-derived growth factor in both skin ulcer healing and period...

background: effects of platelet-derived growth factor b (pdgf-b) on peripheral nerve regeneration was studied using a rat sciatic nerve transection model. materials and methods: forty‑five male, white wistar rats were divided into three experimental groups (n = 15), randomly: normal control group (nc), silicon group (sil), and pdgf‑b treated group (sil/pdgf). in nc group, left sciatic nerve was...

Growth factors released from activated platelets initiate and modulate wound healing in both soft and hard tissues. A recent strategy to promote the wound-healing cascade is to prepare an autologous platelet concentrate suspended in plasma, also known as platelet-rich plasma, that contains growth factors and administer it to wound sites. The purpose of this study was to quantitate platelet numb...

Although altered expression of platelet-derived growth factor (PDGF) is a hallmark of human mesothelioma, expression of PDGF receptors has not been characterized in this cell type. In addition, the expression of this growth factor and its cognate receptor in rodent mesothelioma has not been investigated. In this study, examination of transformed mesothelial cells derived from asbestos-induced r...

The development of neuroprotective strategies to attenuate retinal ganglion cell death could lead to novel therapies for chronic optic neuropathies such as glaucoma. Intravitreal transplantation of mesenchymal stem cells slows retinal ganglion cell death in models of optic nerve injury, but the mechanism of action remains unclear. Here we characterized the neuroprotective effects of mesenchymal...

PURPOSE To evaluate the levels of aqueous humor cytokines in the eyes of patients with central serous chorioretinopathy (CSC) before an intravitreal injection of bevacizumab. METHODS In a prospective interventional trial, 20 eyes of 20 patients with symptomatic CSC of at least 3 months duration and 20 eyes of 20 patients with cataract as control were included. Eyes with CSC received a single ...

The clogging of arteries by neointima is a hallmark of atherosclerosis and of restenosis following balloon angioplasty. The realization in the 1980s that PDGF and its receptor play a key role in the onset of neointimal formation led us to develop PDGFR kinase inhibitors as antirestenosis agents. In this review, we describe the development of these inhibitors and their implementation as antirest...

Platelet-derived growth factors (PDGFs) and their receptors (PDGFRs) are prototypic growth factors and receptor tyrosine kinases which have critical functions in development. We show that PDGFs share a conserved region in their prodomain sequences which can remain noncovalently associated with the mature cystine-knot growth factor domain after processing. The structure of the PDGF-A/propeptide ...
