Effcts of Dextran Sulphate (Dxs) on Lymphocyte Localization in Complement-Deficient Mice: Evidence that the Fifth Component of Complement is not Implicated in the Dxs Activity

AbstractThe effects of subcutaneously or intraperitoneally administered dextran sulphate (DXS) (5nmg/kg) on the subseguent 1 h localization of intravenously injected radiolabelled lymph node cells was investigated in complement deficient mice which lack C5.DXS proved to be equally as potent in depressing cell localizzation in deficient as compared to normal mice. These findings. indicate that the terminal complement components are not, essential for DXS activity.
