YL Hu*, H Li*, WH Li, HX Meng, YZ Fan, WJ Li, YT Ji, H Zhao, L Zhang, XM Jin, FM ZhangFM ZhangOctober 11, 2013 Abstract Plasma gelsolin, the extracellular gelsolin isoform, circulates in the blood of healthy individuals at a concentration of 200 ± 50 mg/l and plays important roles in the extracellular actin-scavenging system during tissue damage. Decreased plasma gelsolin levels have been observed in many …

Osborn TM1, Dahlgren C, Hartwig JH, Stossel TP.April, 2007 Abstract Gelsolin is a highly conserved intracellular actin-binding protein with an extracellular isoform, plasma gelsolin (pGSN). Blood concentrations of pGSN decrease in response to diverse tissue injuries. Depletion of pGSN to critical levels precedes and often predicts complications of injuries such as lung permeability changes and death. Administration of …

Lee PS1, Sampath K, Karumanchi SA, Tamez H, Bhan I, Isakova T, Gutierrez OM, Wolf M, Chang Y, Stossel TP, Thadhani R.May, 2009 Abstract Plasma gelsolin (pGSN) binds actin and bioactive mediators to localize inflammation. Low pGSN correlates with adverse outcomes in acute injury, whereas administration of recombinant pGSN reduces mortality in experimental sepsis. We found that mean pGSN levels of 150 patients randomly selected …

Lee PS1, Drager LR, StosselTP, Moore FD, Rogers SO.March, 2006 Abstract OBJECTIVE:To examine the relationship between plasma gelsolin levels and mortality following surgery or trauma.BACKGROUND:Few simple predictive diagnostic tests are available to predict mortality following surgery or trauma. We hypothesize that plasma concentrations of gelsolin, a protein that responds to injured tissue, might be a predictor of patient outcomes.METHODS:We …

Osborn TM1, Verdrengh M, Stossel TP, Tarkowski A, Bokarewa M.September, 2008 Abstract INTRODUCTION: Gelsolin is an intracellular actin-binding protein involved in cell shape changes, cell motility, and apoptosis. An extracellular gelsolin isoform, plasma gelsolin circulates in the blood of healthy individuals at a concentration of 200 +/- 50 mg/L and has been suggested to be a key component of …

Plasma gelsolin is a marker and therapeutic agent in animal sepsis. Lee PS1, Waxman AB, Cotich KL, Chung SW, Perrella MA, Stossel TP. Abstract OBJECTIVE: Plasma gelsolin is a circulating actin-binding protein that serves a protective role against tissue injuries. Depletion of plasma gelsolin in systemic inflammation may contribute to adverse outcomes. We examined the role of plasma gelsolin in …

Bucki R1, Byfield FJ, Kulakowska A, McCormick ME, Drozdowski W, Namiot Z, Hartung T, Janmey PA.October 1, 2008 Abstract The various functions of gelsolin in extracellular compartments are not yet clearly defined but include actin scavenging and antiinflammatory effects. Gelsolin was recently reported to bind endotoxin (LPS) from various Gram-negative bacteria with high affinity. In this study we investigate whether gelsolin also …
