These findings indicate BDCA2 plays a dual role in the immune response to Vidu, with the amount of anti-Qb antibody coating Vidu determining whether interaction of Vidu with BDCA2 results in pDC activation or inhibition. This important mechanistic information could influence the design of the next generation of pDC-targeting immunotherapeutic nanoparticles.

Here, we developed a novel whole-cell vaccine, termed MDLSD, by combining mitoxantrone (MTX)-induced ICD with the TLR9 agonist SD-101. Furthermore, mice cured by MDLSD developed long-term immunological memory, characterized by a recall response dominated by IFN-γ+ CD8+ and TNF-α+ T cells, enabling rejection of secondary tumor challenges. Collectively, our findings illustrate that the MDLSD vaccine synergizes the antigenic breadth of ICD with potent TLR9 stimulation to elicit robust DC activation, polyfunctional T-cell responses, and durable immunological memory, offering a compelling strategy for cancer immunotherapy.

To our knowledge, this study is among the first to evaluate the combination of CpG7909 lipoplexes with anti-PD1 antibodies in the context of cancer immunotherapy. The findings suggest that this approach may convert the TME from an immunologically "cold" to "hot" state, thereby enhancing tumor suppression and potentially improving the response rate to ICIs.

In summary, endosomal TLRa VLPs all have the ability to activate pDCs, however, combined TLR7/8 activation using TLR7/8a VLPs was significantly more effective than the other VLPs at activating T cells and was dependent on direct contact with pDCs. Therefore, TLR7/8a VLPs may potentially induce a robust anti-tumor immune response and warrant further investigation for cancer therapy.
