Findings reveal enhanced tumor immunity via dendritic cells in melanoma, suggesting strategies to improve immunotherapy outcomes.

This research aims to explore how FLT3-L-dependent dendritic cells affect tumor immunity and responses to immunotherapy.
Evaluated tumor growth in mice with varying levels of cDCs.
Analyzed immune cell dynamics including Tregs and NK cells with different cDC levels.
Examined transcriptomic signatures in cancer patient biopsies across multiple cancer types.
Both low and high levels of cDCs correlate with improved survival in melanoma mice.
Increased Treg infiltration inhibits immune response; Treg depletion combined with cDC boost enhances survival.
Transcriptomic analysis highlights paradoxical effects of cDC levels on survival across 35 human cancers.

Darrasse-Jeze et al. (2025) studied this question.
