Table 1. Effect of cytokines or coculture with platelets on MC CD40 expressiona

StimuliCD40 (MFI)
a Shown is the MFI of CD40 expression on mesangial cells (MC) after culturing for 24 h in the presence or absence of rTNF-α, rIFN-γ, or a 100 excess of platelets. Similar results were obtained from three different experiments.
Medium21.0
rTNF-α (10 ng/ml)51.1
rIFN-γ (500 U/ml)43.3
Platelets (MC:platelets = 1:100)119.7
