huFLT3L treatment robustly expanded the cDC1 population in intracerebral SB28-OVA-FL tumor-draining lymph nodes and the fraction of these cross-presenting SIINFEKL, but it had no significant effect on cDC1 abundance or cross-presentation in subcutaneous tumor-draining lymph nodes (figure 4G and online supplemental figure S4J, K). The gene discussed is MPPE1; the disease is neoplasm.
