Background: Dendrimers are hyperbranched polymeric nanomaterials increasingly used in research, industrial and biomedical applications. Establishing safety profile of these particles includes an understanding of their interactions with blood components and the immune system.
Method: Herein I review the literature demonstrating how tuning dendrimer physicochemical properties influences their interaction with erythrocytes, platelets, plasma proteins, complement and coagulation systems. Dendrimer immunogenicity, adjuvanticity, allergenicity, anti-inflammatory, immunosuppressive and antibacterial properties are also discussed.
Conclusion: Dendrimers hemato- and immune- compatibility are determined by particle size, architecture, type and density of surface functional groups. Case studies from the literature are discussed to support this conclusion. The review also highlights questions which require more thorough investigation to fill the gaps in our understanding of immunological properties of dendrimers.
