Abstract
[Escherichia coli] endotoxin (ET) pre-treatment of mice resulted in increased liver and spleen uptake and decreased circulating levels of aggregated Ig[immunoglobulin]G (AggIgG) compared to control animals. ET had no effect upon the uptake of AggIgG by lung or whole kidney cortex. Immunofluorescent microscopy revealed increased localization of AggIgG in the mesangium of ET mice at 1 but not at 2 or 16 h after administration of AggIgG. Mesangial macromolecular uptake is not solely dependent upon blood levels but may be influenced by unknown and probably complex variables.
