Nanomaterials Trigger Functional Anti-Tumoral Responses in Primary Human Immune Cells.

ABSTRACT: Targeting the immune system with nanoparticles (NPs) to deliver immunomodulatory molecules emerged as a solution to address intra-tumoral immunosuppression and enhance therapeutic response. While the potential of nanoimmunotherapies in reactivating immune cells has been evaluated in several preclinical studies, the impact of drug-free nanomaterials on the immune system remains unknown. Here, the molecular and functional response of human NK cells and pan T cells to a selection of five NPs that are commonly used in biomedical applications are characterized. After a pre-screen to evaluate the toxicity of these nanomaterials on immune cells, ultrasmall silica-based gadolinium (Si-Gd) NPs and poly(lactic-co-glycolic acid) (PLGA) NPs are selected for further investigation.
