SIRPA and neoplasm: Similar results were obtained from a repeat experiment, in which mice vaccinated with CD47KO tumor cells showed a significant increase in the frequencies of total CD11c+SIRPα+ DCs (Fig. 5e), and activated I-AbhiSIRPα+CD11c+ (Fig. 5f), CD40+SIRPα+CD11c+ (Fig. 5g), CD86+SIRPα+CD11c+ (Fig. 5h) DCs in spleens compared to mice receiving WT tumor vaccination.
