( A ) Interaction of nanoparticles (NPs) with macrophages and the regulation of macrophage pro/anti-inflammatory functions by NPs. (I) Upon entering the body, NPs bind to plasma proteins and are internalized by macrophages. NPs are endocytosed into endosomes, degraded, and then released extracellularly to exert their active effects; other endosomes fuse with lysosomes to form endolysosomes, exerting intracellular effects. (II) First, NPs can eliminate macrophage activation by phagocytosis and restriction of pathogen-associated molecular patterns (PAMPs); second, they inhibit the interaction between PAMPs and pattern recognition receptors (PRRs); third, NPs that enter the cytoplasm inhibit the transmission of inflammatory signaling pathways; finally, NPs inhibit the release of active products from inflammatory pathways, controlling cell and tissue damage caused by overactivated macrophages. (III) NPs modulate the pro-inflammatory activity of macrophages. NPs can enhance PRR activation to initiate macrophage inflammatory responses. Once in the cytoplasm, NPs activate downstream pathways and inflammasomes to induce the production of pro-inflammatory factors. NPs, nanoparticles; PAMPs, pathogen-associated molecular patterns; ROS, reactive oxygen species; ILs, interleukins; TNFs, tumor necrosis factors; MAPK, mitogen-activated protein kinase; NF-kB, nuclear factor-κB. ( B ) Regulation of macrophage polarization by nanoparticles (NPs). M1-type macrophages typically function during the cytokine storm phase of sepsis, releasing large amounts of pro-inflammatory mediators, including reactive oxygen species (ROS), interferons (IFNs), interleukins (ILs), and tumor necrosis factors (TNFs). In contrast, M2-type macrophages usually appear during the immune paralysis phase, secreting anti-inflammatory mediators, most notably IL-10. During excessive inflammatory stimulation, the continuous release of pro-inflammatory mediators by M1-type macrophages causes damage to the body, whereas, during immune paralysis, excessive activation of M2-type macrophages increases the risk of secondary infections. NPs can modulate macrophage polarization at different stages of sepsis to improve prognosis. NPs, nanoparticles; ROS, reactive oxygen species; ILs, interleukins; IFNs, interferons; TNFs, tumor necrosis factors. ( C ) Interference of macrophage pyroptosis by nanoparticles (NPs). NPs can block the activation of caspase-1 and caspase-4/5/11, reducing the release of DAMPs (damage-associated molecular patterns) and preventing unnecessary tissue and cell damage.

( A ) Schematic illustration of the synthesis, antibacterial mechanism, and regulation of macrophage polarization by CeO2@Ce6 nanocomposites for the treatment of periodontal disease. The enhanced antibacterial efficiency of CeO2@Ce6 may rely on ROS produced by aPDT and the inherent antibacterial activity of CeO2. Nanocomposites containing CeO2 exhibit SOD- and CAT-mimetic activities, capable of scavenging excess ROS by switching between Ce(III) and Ce(IV) states. CeO2@Ce6 nanocomposites can actively modulate macrophage polarization from the pro-inflammatory M1 phenotype to the anti-inflammatory (regenerative) M2 phenotype.

( A ) (I) Schematic and the actual structure of the system. Schematic representation of the structure of toxin nanosponges and their mechanism for neutralizing pore-forming toxins (PFTs). (II) TEM (transmission electron microscopy) images of nanosponges mixed with α-toxin (scale bar, 80 nm) and an enlarged view of a single toxin-adsorbed nanosponge (scale bar, 20 nm). Samples were negatively stained with uranyl acetate before TEM imaging. ( B ) In vivo toxin neutralization. (I–III) Skin lesions in mice three days after injection with α-toxin. (IV–VI) No skin lesions in mice injected with α-toxin/nanosponge mixture. Each group had n = 6 mice. Reproduced from Hu CM, Fang RH, Copp J, Luk BT, Zhang L.
