LPS-desensitized DC are potent stimulators of allogeneic T-cell proliferation. DC were cultured in the presence or absence of LPS at the concentrations indicated. Day-5 DC were irradiated and used as stimulators of allogeneic T-cell proliferation. Proliferation was monitored by measuring [methyl-3H]thymidine uptake on day 5 of coculture. Each value represents the mean cpm of triplicate cultures with SD.
