Manipulation of DC targeting the master regulator TANK‐binding Kinase 1 (TBK1) might be useful to acquire controller‐like properties. Here, we evaluated the impact of the combination of 2´3´‐c´diAM(PS)2 and Poly I:C as potential adjuvants capable of potentiating DC´s abilities to induce polyfunctional HIV‐1 specific CD8 + T‐cell responses in vitro and in vivo using a humanized BLT mouse model. Adjuvant combination enhanced TBK‐1 phosphorylation and IL‐12 and IFN‐β expression on DC and increased their ability to activate polyfunctional HIV‐1‐specific CD8 + T cells in vitro . Moreover, higher proportions of hBLT mice vaccinated with ADJ‐DC exhibited less severe CD4 + T‐cell depletion following HIV‐1 infection compared to control groups. This was associated with infiltration of CD8 + T cells in the white pulp from the spleen, reduced spread of infected p24 + cells to LN, and with preserved abilities of CD8 + T cells from the spleen and blood of vaccinated animals to induce specific polyfunctional responses upon antigen stimulation. Therefore, priming of DC with PolyI:C and STING agonists might be useful for future HIV‐1 vaccine studies.","journal":"European Journal of Immunology","year":2021,"id":187545,"datarank":0.0,"base_score":0.0,"endowment":0.0,"self_citation_contribution":0.0,"citation_network_contribution":0.0,"self_endowment_contribution":0.0,"citer_contribution":0.0,"corpus_percentile":null,"corpus_rank":null,"citation_count":18,"citer_count":0,"citers_with_citation_signal":0,"citers_with_endowment":0,"datacite_reuse_total":0,"is_dataset":false,"is_dataset_confidence":0.9581,"is_data_producer":false,"deposit_databanks":null,"is_oa":true,"file_count":0,"downloads":0,"has_version_chain":false,"published_date":"2021-01-01","fair_score":null,"fair_percentile":null,"algorithm_id":"datarank_citation_only_1hop_v6","ranking_scope":"data_only","authors":[{"id":321609,"name":"Daniel T.
