Interactions between nanoparticle corona proteins and the immune system

Curr Opin Biotechnol. 2023 Oct 16;84:103010. doi: 10.1016/j.copbio.2023.103010. Online ahead of print.ABSTRACTThe corona surrounding nanoparticles (NPs) in serum contains proteins such as complement, immunoglobulins, and apolipoproteins that can interact with the immune system. This review article describes the impact of these interactions on nanomedicine stability, biodistribution, efficacy, and safety. Notably, it highlights the latest findings on the generation of antibody responses to the polyethylene glycol (PEG) component of SARS-CoV-2 mRNA vaccines and possible mechanisms of hypersensitivity reactions induced by antibodies that bind to NPs. Finally, we briefly outline how the NP interactions with immune cells can be harnessed to enhance targeted delivery of nanocargos to disease sites.PMID:37852029 | DOI:10.1016/j.copbio.2023.103010
