Therapeutic applications of nanoparticles targeting neutrophil and extracellular traps

Abstract

Neutrophils, the most abundant leukocytes in human circulation, are key effectors and regulators of both innate and adaptive immunity which migrate from the bloodstream to sites of inflammation or infection in response to different stimuli. A growing body of evidence has revealed that dysregulated neutrophil activity contributes to the development of several diseases. Targeting their function has been proposed as a potential strategy to treat or mitigate the progression of these disorders. Additionally, neutrophil tropism has been proposed as a strategy to drive therapeutic agents towards targeted disease sites. In this article, we review the proposed nanomedicine approaches to target neutrophils and their components, the regulation of their function and the use of their tropism in drug delivery for therapeutic purposes.
