Hiltonol and pRNA stimuli induce an immune activating profile in the transcriptomics of cDC1s

Project description:8 ligand), and compared these samples to unstimulated counterparts. Both methods, RNA-seq and microarray, gave very similar results and showed that Hiltonol and pRNA lead to almost identical changes in the transcriptome of cDC1 mDCs. A gene ontology (GO) term analysis suggested that these changes were mainly related to activation and maturation pathways, including induction of type I IFN and IL-12 transcription, while pathways related to adverse effects or cell damage were not strongly affected. The combination of both reagents in the DC cultures gave a very similar result as compared to either stimulus alone, suggesting no synergistic effect. Together, our results indicate that both stimuli are potent clinical grade adjuvants with comparable effects to mature cDC1 mDCs within an immunogenic profile in short-term cultures suitable to be used in immunotherapy.

Hiltonol and pRNA stimuli induce an immune activating profile in the transcriptomics of cDC1s [Affy]

Project description:Stimulation of dendritic cells (DC) is considered critical in cancer immunotherapy. BATF-3–dependent subsets, that express in humans BDCA-3 (CD141), promote CD8 T-cell cross-priming against tumor antigens. Here, we evaluate two clinical grade stimuli for peripheral blood cDC1 myeloid dendritic cells (mDCs), a rare DC subset that is currently being explored for use in immunotherapy. In contrast to routine evaluation methods, which focus on predefined maturation markers on the surface or factors released from the activated cells, we applied an unbiased transcriptome-based method using both RNA-sequencing (RNA-seq) and microarrays. Specifically, we analyzed the mRNA of cDC1 mDCs from five human donors upon activation with two clinical-grade adjuvants, Hiltonol (poly IC, a TLR3 ligand, called Stimulus 1 in the description below) and protamine RNA (pRNA, aTLR7/8 ligand, Stimulus 2), and compared these samples to unstimulated counterparts. Both methods, RNA-seq and microarray, gave very similar results and showed that Hiltonol and pRNA lead to almost identical changes in the transcriptome of cDC1 mDCs.
