Tumor-Associated Antigen-Presenting Function of Dendritic Cells (TAA-Presenting DCs)

Target
TAA-Presenting DCs
Molecular classification
Antigen-Presenting Cell, Dendritic Cell, MHC Class I presentation, MHC Class II presentation
01

Overview

Dendritic cells (DCs) are professional antigen-presenting cells (APCs) crucial for initiating anti-tumor immune responses. They capture, process, and present tumor-associated antigens (TAAs) to T lymphocytes, stimulating cytotoxic T cell responses. Key mechanisms include direct presentation, cross-presentation (especially by cDC1 DCs), and cross-dressing. Dysfunctional DCs contribute to immune evasion, while enhancing their TAA presentation can improve anti-tumor immunity through vaccines and in situ modulation.
