Special Issue Information
Dear Colleagues,
Effective cancer immunotherapy depends not only on T-cell reinvigoration but also on the presence and functionality of dendritic cells (DCs) within the native tumor immune microenvironment. Checkpoint blockade and other immunostimulatory agents—such as agonists of STING, CD40, FLT3, or TLR pathways—ultimately rely on intratumoral DCs to capture antigens, mature appropriately, and prime or re-prime effector T-cells. Insufficient numbers or impaired activation of tumor-resident DC subsets have emerged as key barriers to response, while preserved DC niches correlate strongly with therapeutic benefit across cancers. Understanding these DC-dependent mechanisms requires experimental systems that maintain the full complexity of cancer immune infiltrates, including native myeloid, lymphoid, and stromal components.
This Special Issue welcomes studies dissecting how immune checkpoint inhibitors and immunostimulatory agents modulate DC biology, antigen presentation, and T-cell dynamics within tumor ecosystems. We encourage submissions leveraging advanced in situ and ex vivo approaches—such as spatial profiling, organoids retaining endogenous immune populations, and single-cell multi-omics—to reveal how DCs integrate microenvironmental cues and modulate sensitivity or resistance to immunotherapy. Work bridging mechanistic insights with translational or clinical findings is particularly valued.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as communications are invited. For planned papers, a title and short abstract (about 250 words) can be sent to the Editorial Office for assessment.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Cancers is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2900 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
