Nanoparticles enhance immune response through various mechanisms:
- Enhanced Uptake by Antigen-Presenting Cells (APCs): Nanoparticles are efficiently taken up by dendritic cells and macrophages, leading to better antigen presentation. - Targeted Delivery: Functionalized nanoparticles can target specific cells or tissues, ensuring that the adjuvant reaches the desired site of action. - Prolonged Release: Nanoparticles can provide sustained release of the adjuvant, maintaining a prolonged immune stimulus.
