Figure 1From: Chemiluminescence detection of reactive oxygen species in isolated Kupffer cells during phagocytosis of Treponema pallidumGeneration of ROS by Kupffer cells incubated with various preparations of T. pallidum. Cells were incubated with live (e), heat-inactivated opsonized (b), heat-inactivated (d), or live opsonized (c) spirochetes, as well as with phorbol myristate (a). In the inset, dose-response curves for heat inactivated and opsonized (à) and heat inactivated (à) treponemes are shown.Back to article page
