DC are the APCs involved in presentation of SL-encapsulated antigen in vivo.
Two mice were injected with 10 μg OVA-SL subcutaneously. Draining LN (dLN) and nondraining LN (ndLN) were removed 3 days later. Single-cell suspensions from LN were pooled, separated magnetically into CD11c+ and CD11c− fractions, and applied in graded doses to 3 × 105 CD8+ T cells from OT-1 mice. After 24 hours, T-cell proliferation was assayed by thymidine incorporation. Mean cpm × 10−3 from a representative experiment (1 of 2) are shown.
