Proliferative glomerulonephritis in humans is characterized by the presence of leukocytes in glomeruli. Granulocyte-macrophage colony-stimulating factor (GM-CSF) and granulocyte colony-stimulating factor (G-CSF) can potentially stimulate or affect T cell, macrophage, and neutrophil function. To define the roles of GM-CSF and G-CSF in leukocyte-mediated glomerulonephritis, glomerular injury was ...

B lymphocytes were purified from the peripheral blood of 30 B-cell chronic lymphocytic leukemia (B-CLL) patients and tested for the ability to produce granulocyte colony-stimulating factor (G-CSF) in vitro. Fifteen Staphylococcus aureus Cowan I (SAC)-stimulated, but not unstimulated, B-cell suspensions produced G-CSF in short-term cultures. Accordingly, G-CSF mRNA was detected only in SAC-stimu...

Granulocyte-colony stimulating factor (G-CSF) has molecular structures and intracellular signaling pathways that are similar to those of leptin and ciliary neurotropic factor (CNTF). It also has immune-modulatory properties. Given that leptin and CNTF play important roles in energy homeostasis and that obesity is an inflammatory condition in adipose tissue, we hypothesized that G-CSF could also...

BACKGROUND Pegylated granulocyte colony-stimulating factor (G-CSF) has recently been introduced as a new compound for mobilization of CD34(+) hematopoietic stem and progenitor cells. In this study, we compared the molecular and functional characteristics of CD34(+) cells mobilized by pegylated G-CSF with those mobilized by unconjugated G-CSF. DESIGN AND METHODS Gene expression of immunomagnet...
