CPH inhibit alloantigen-induced T cell proliferation. Responder T cells (R1) were preincubated with peptides M/W or without peptides (None). R1 were mixed with irradiated stimulator cells of a second donor (R1+*S2) or as control with autologous stimulator cells (R1+*S1). Irradiated stimulator cells of both donors incubated alone (*S1 and *S2) served as further controls. Proliferation was determined after 48 h by ³H incorporation. Two independent experiments are shown (means ± SE of triplicate wells).
