Uptake of apoptotic CTCL cells increases class I and II MHC expression on the maturing DCs.

(A,B) Flow cytometry demonstrates increased class I and II MHC expression on the maturing DCs after overnight incubation with CTCL cells that had been rendered apoptotic by CD3 antibody. The white curve demonstrates class I or II binding at T0. The black curve demonstrates enhanced class I or II expression after overnight incubation with apoptotic CTCL cells.
