Raises a question worth testing. It does not answer one.
This is a narrative review of the role of regulatory T cells in bladder cancer immunosuppression and their therapeutic targeting. It synthesizes mechanistic insights and proposes therapeutic strategies but presents no original data, clinical outcomes, or comparative evidence to support practice change.
Journal article. Patients with bladder cancer; the review does not report original patient data..
Tregs accumulate in bladder tumors and are associated with disease progression and reduced response to immunotherapies. The bladder cancer TME provides multiple signals promoting Treg recruitment through chemokine-mediated trafficking, metabolic adaptation, and cytokine-driven differentiation. Single-cell transcriptomics and multiomics analyses reveal substantial heterogeneity among tumor-infiltrating Tregs with specialized subsets.

This review offers a conceptual framework for understanding Treg-mediated immune suppression in bladder cancer but does not provide clinical trial data or outcome measures to guide immediate therapeutic decisions. Clinicians should view the proposed therapeutic strategies as preliminary concepts requiring empirical validation.

Bladder cancer is characterized by a highly dynamic tumor microenvironment (TME) that critically influences tumor progression, immune evasion, and therapeutic responsiveness. Among the immune populations in the TME, regulatory T cells (Tregs) play a central role in maintaining immune tolerance but also suppress effective antitumor immunity. Increasing evidence suggests that Tregs accumulate in bladder tumors and are associated with disease progression and reduced response to immunotherapies. The bladder cancer TME provides multiple signals that promote Treg recruitment, expansion, and functional stabilization, including chemokine-mediated trafficking, metabolic adaptation, and cytokine-driven differentiation. Interactions between Tregs and other microenvironmental components, such as cancer-associated fibroblasts, tumor-associated macrophages, endothelial cells, and extracellular matrix elements, further reinforce the immunosuppressive niche that facilitates tumor survival and therapy resistance. Recent advances in single-cell transcriptomics, spatial profiling, and multiomics analyses have revealed substantial heterogeneity among tumor-infiltrating Tregs, suggesting the existence of specialized subsets with distinct functional and metabolic properties in the bladder TME. These emerging insights highlight the importance of understanding Treg–TME crosstalk in shaping the immune landscape of bladder cancer. Targeting the mechanisms regulating Treg recruitment, stability, or suppressive function may represent a promising strategy to enhance the efficacy of immunotherapies including Bacillus Calmette–Guérin therapy. This review summarizes recent advances in Treg biology in bladder cancer and highlights potential therapeutic strategies to modulate Treg-mediated immunosuppression in the TME.
