Inflammation is part of the physiological response of the organism to infectious diseases caused by organisms such as bacteria, viruses, fungi, or parasites. Innate immunity, mediated by mononuclear phagocytes, including monocytes and macrophages, is a first line of defense against infectious diseases and plays a key role triggering the delayed adaptive response that ensures an efficient defense against pathogens. Monocytes and macrophages stimulation by pathogen antigens results in activation of different signaling pathways leading to the release of proinflammatory cytokines. However, inflammation can also participate in the pathogenesis of several diseases, the autoimmune diseases that represent a relevant burden for human health. Dendrimers are branched, multivalent nanoparticles with a well-defined structure that have a high potential for biomedical applications. To explore new approaches to fight against the negative aspects of inflammation, we have used neutral high-generation phosphorus dendrimers bearing 48 (G3) or 96 (G4) bisphosphonate groups on their surface. These dendrimers show no toxicity and have good solubility and chemical stability in aqueous solutions. Here, we present data indicating that neutral phosphorus dendrimers show impressive antiinflammatory activities both in vitro and in vivo. In vitro, these dendrimers reduced the secretion of proinflammatory cytokines from mice and human monocyte-derived macrophages. In addition, these molecules present efficient antiinflammatory activity in vivo in a mouse model of subchronic inflammation. Taken together, these data suggest that neutral G3-G4 phosphorus dendrimers have strong potential applications in the therapy of inflammation and, likely, of autoimmune diseases.
