Summary It was obvious to all in attendance that the dialogue concerning not only HIV but all infectious agents must be continued as part of these international placental conferences. It was noted with pleasure that significant advances have occurred

Summary In order to further understand the mechanisms of HIV transmission from mother to child, the susceptibility of Hofbauer cells to the monocyte-tropic strain HIV-1Ba-L was tested in vitro. Hofbauer cells were obtained from normal full term place

Ca2+ entry through L-type voltage-sensitive Ca2+ channels stimulates the release of human chorionic gonadotrophin and placental lactogen by placental explants

Autor: Philippe Lebrun, Bruno Polliotti, Claude Robyn, Sylvain Meuris

Publikováno v: Biochimica et Biophysica Acta (BBA) - Molecular Cell Research. 1220:101-106

The release of human chorionic gonadotrophin (hCG) and placental lactogen (hPL) by human placental explants can be stimulated by Ca2+ entry. The aim of the present study was to characterize the modality of Ca2+ entry in the presence of high extracell

Calcium influx similarly stimulates the release of chorionic gonadotrophin and placental lactogen from human placental explants

Autor: Claude Robyn, Sylvain Meuris, Bruno Polliotti, Philippe Lebrun

Publikováno v: Placenta. 13:189-198

Summary The releases of human chorionic gonadotrophin (hCG) and of human placental lactogen (hPL) by explants from normal term placentae were both stimulated by calcium, barium, ionomycin, and forskolin. The stimulatory effect of calcium could be thw

The release of human chorionic gonadotrophin and placental lactogen by placental explants can be stimulated by Ca2+ entry through a Na(+)-Ca2+ exchange process

Autor: Bruno Polliotti, Claude Robyn, Philippe Lebrun, Sylvain Meuris

Publikováno v: Placenta. 15(5)

Isosmotical replacement of extracellular Na+ ([Na+]o) by K+, choline and to a lesser extent by saccharose stimulated the release of chorionic gonadotrophin and placental lactogen from human term placental explants. The effect of [Na+]o removal on the

Publikováno v: Clinical immunology and immunopathology. 71(1)

Peripheral blood mononuclear cells were quantified for the subsets of CD4, CD8, and CD19 lymphocytes by using CD45RA (2H4), CD29(4B4), CD57, CD5, CD10, Leu8, HLA-DR, and TCR gamma delta-1 monoclonal antibodies and dual color immunofluorescence. A com

Stimulatory effects of extracellular calcium on chorionic gonadotrophin and placental lactogen release by human placental explants

Autor: Claude Robyn, Philippe Lebrun, Sylvain Meuris, Bruno Polliotti

Publikováno v: Placenta. 11(2)

The effects of sudden modifications of extracellular calcium ion concentration on human chorionic gonadotrophin (hCG) and human placental lactogen (hPL) release were investigated using term placental explants incubated in Krebs Ringer solution. The h
