Treatment of human monocytes with vascular endothelial growth factor (VEGF) isolated from tumor cell supernatants was reported to induce monocyte activation and migration. In this study we show that recombinant human VEGF165, and VEGF121 had a maximal effect on human monocyte migration at 65 to 250 pmol/L. Chemotactic activity of VEGF165 was inhibited by a specific antiserum against VEGF, by he...
Cultured rabbit aortic and human carotid artery endothelial cells produced a factor that was chemotactic for monocytes but not for neutrophils. Checkerboard analysis showed that the activity was due to chemotaxis and not to chemokinesis. The factor was produced in both serum-containing and serumless media. Treatment with carboxypeptidase and trypsin resulted in inhibition of chemotactic activit...
Native low density lipoprotein (LDL) does not affect monocyte/macrophage motility. On the other hand, oxidatively modified LDL inhibits the motility of resident peritoneal macrophages yet acts as a chemotactic factor for circulating human monocytes. We now show that lysophosphatidylcholine (lyso-PtdCho), which is generated by a phospholipase A2 activity during LDL oxidation, is a potent chemota...
All-trans retinoic acid (ATRA) can induce acute respiratory distress syndrome in patients with acute promyelocytic leukaemia (APL). The current study investigated the role of monocyte chemotactic protein (MCP)-1 in the chemotactic transmigration of ATRA-treated NB4 (ATRA-NB4) APL cells toward A549 alveolar epithelial cells. NB4 and A549 cells were separately cultured with ATRA and/or dexamethas...
Human alpha-thrombin, the procoagulant activation product of prothrombin, elicits chemotaxis in human peripheral blood monocytes and several macrophagelike continuous cell lines, most notably J-774.2, but not in human peripheral blood granulocytes. alpha-Thrombin is effective in stimulating cell movement at concentrations ranging from 10(-10) to 10(-6) M but is optimally active at 10(-8) M. At ...
Human immunodeficiency virus type 1 (HIV-1)-associated dementia (HAD) is correlated with increased monocyte migration to the brain, and the incidence of HAD among otherwise asymptomatic subjects appears to be lower in India than in the United States and Europe (1 to 2% versus 15 to 30%). Because of the genetic differences between HIV-1 strains circulating in these regions, we sought to identify...
Cancer development is often associated with increased fibroblast proliferation and extensive fibrosis; however, the role of fibroblasts during carcinogenesis remains largely unknown. Using the 7,12-dimethylbenz-(a)anthracene and 12-O-tetradecanoylphorbol-13-acetate-induced two-stage skin carcinogenesis model, we demonstrated here that there was a massive accumulation and proliferation of fibrob...
