Takeshita, Keisuke, Yamasaki, Tsugiko, Akira, Shizuo, Gantner, Florian, Bacon, Kevin B.

Contact hypersensitivity (CHS) induced by a hapten is thought to be mediated by T helper type 1 (Th1) cells. However, FITC can induce contact allergy in vivo, and in vitro studies suggest that this...

Takeshita, Keisuke, Yamasaki, Tsugiko, Nagao, Koichi, Sugimoto, Hiromi, Shichijo, Michitaka, Gantner, Florian, ...

Chemoattractant receptor‐homologous molecule expressed on Th2 lymphocytes, CRTH2, is a cognate receptor for prostaglandin (PG) D2 and, in humans, is suggested to play a functional role in...

Phagocytosis of Nonapoptotic Cells Dying by Caspase-Independent Mechanisms (2000)

Hirt, Ulrich, Gantner, Florian, Leist, Marcel

Caspase activation, exposure of phosphatidylserine (PS) on the outer surface of the plasma membrane, and rapid phagocytic removal of dying cells are key features of apoptosis. Nonapoptotic/necrotic...

Cytokine-Mediated Hepatic Apoptosis (1998)

Leist, Marcel, Gantner, Florian, Künstle, Gerald, Wendel, Albrecht

Thirty years ago liver pathology defined apoptosis as a novel mode of cell death. Recently, experimental models of liver injury have been made available for examining the signaling molecules and...

Tumor necrosis factor-induced apoptosis during the poisoning of mice with hepatotoxins (1997)

Leist, Marcel, Gantner, Florian, Naumann, Heike, Bluethmann, Horst, Vogt, Kathrin, Brigelius-Flohe, Regina, ...

BACKGROUND & AIMS: Treatment with tumor necrosis factor (TNF) induces murine hepatocyte apoptosis in vitro and in vivo when sensitizing concentrations of toxins are present. The aim of this study was...

DNA Fragmentation In Mouse Organs during Endotoxic Shock (1996)

Bohlinger, Ines, Leist, Marcel, Gantner, Florian, Angermüller, Sabine, Tiegs, Gisa, Wendel, Albrecht

The systemic inflammatory response syndrome has still an unpredictable outcome, and patients often die of multiple organ failure despite circulatory stabilization therapy. The still incompletely...

T Cell Stimulus-Induced Crosstalk between Lymphocytes and Liver Macrophages Results in Augmented Cytokine Release (1996)

Gantner, Florian, Leist, Marcel, Küsters, Sabine, Vogt, Katrin, Volk, Hans-Dieter, Tiegs, Gisa

Polyclonal T cell stimulation in humans leads to a cytokine burst syndrome that may result in organ failure or lethality. Mechanisms of such cytokine-dependent morbidity can be studied in mice...

The 55-kD tumor necrosis factor receptor and CD95 independently signal murine hepatocyte apoptosis and subsequent liver failure (1996)

Leist, Marcel, Gantner, Florian, Künstle, Gerald, Bohlinger, Ines, Tiegs, Gisa, Bluethmann, Horst, ...

BACKGROUND: Activation of either the 55-kD tumor necrosis factor receptor (TNF-R1) or CD95 (Fas/Apo-1) causes apoptosis of cells and liver failure in mice, and has been associated with human liver...

Concanavalin A - induced T-cell - mediated hepatic injury in mice : The role of tumor necrosis factor (1995)

Gantner, Florian, Leist, Marcel, Lohse, Ansgar Wilhelm, Germann, Paul Georg, Tiegs, Gisa

Concanavalin A activates T lymphocytes in vitro and causes T-cell-dependent hepatic injury in mice. T lymphocytes were previously identified as effector cells of concanavalin A-induced liver injury....

Tumor necrosis factor-induced hepatocyte apoptosis precedes liver failure in experimental murine shock models (1995)

Leist, Marcel, Gantner, Florian, Bohlinger, Ines, Tiegs, Gisa, Germann, Paul Georg, Wendel, Albrecht

Activation of the 55 kDa TNF receptor is necessary and sufficient for TNF-induced liver failure, hepatocyte apoptosis, and nitrite release (1995)

Leist, Marcel, Gantner, Florian, Jilg, Sabine, Wendel, Albrecht

The systemic inflammatory response is characterized by release of circulating TNF which may cause multiorgan failure including septic liver failure. We studied TNF signaling in an appropriate in...
