Abstract:
AIM: To investigate the effect of LPS on phagocytosis of Kupffer cells in vitro. METHODS: Isolated Kupffer cells were treated with LPS in vitro . The phagocytosis, microfilament, microtubules and apoptosis of Kupffer cells were determined by the beads phagocytosis test, fluorescence staining, fluorometry and flow cytometric analysis. RESULTS: LPS enhances the phagocytosis, actin content, microtubules fluorescence density of Kupffer cells in vitro , while at a large dose or for a long time, it lessened the phagocytosis increasing or phagocytosis, inhibites the microfilament and microtubules expression, and induced apoptosis. CONCLUSION: LPS enhances the phagocytosis of Kupffer cells in vitro , but in large amount, it inhibites the phagocytosis of Kupffer cells, which is probably related to LPS -induced microfilament, microtubules expression changes and apoptosis in Kupffer cells.
