PG - 172-5 LID - 10.1007/BF02959257 [doi] AB - Tumor necrosis factor-alpha (TNF-alpha) is released from blood-free perfused rat liver by the fungal metabolite ochratoxin A. Here we have identified Kupffer cells as the sole source of OTA-mediated cytokine release. If single cell preparation of Kupffer cells, hepatocytes, or sinusoidal endothelial cells were prepared from rat livers, only Kupffer cells released TNF-alpha upon incubation with 2.5 mumol/l OTA. OTA failed to induce TNF-alpha release in the blood-free perfused isolated rat liver when Kupffer cells were blockedin vitro by 15 mumol/l gadolinium chloride. When rats were pretreatedin vivo with the Kupffer cell depleting clodronate liposomes, OTA-mediated TNF-alpha release was abrogated in the isolated perfused liver model.
