Effects of dexamethasone on complement-regulatory protein expression.

DHL-4, FL-18, and Tab cell lines are significantly more sensitive to complement following dexamethasone exposure; however CD59, CD55, and CD46 expression is not significantly changed by dexamethasone. The mean fluorescence intensity for treated (dark) and untreated (light) cells are not significantly different (mean of 3 samples). This is representative of 2 experiments performed.
