CCzymes inhibit the secretion of pro-inflammatory cytokines downstream of the MAPK and PI3K-Akt signaling pathways by suppressing the expression of the gene encoding the receptor tyrosine kinase protein (Kit). At the same time, CCzymes inhibited the HIF-1 and JAK-STAT signaling pathways, which in turn inhibited M1-type polarization of macrophages. In addition, CCzymes selectively inhibit pathogenic bacteria while promoting the growth of beneficial microbiota, thus achieving a balanced gut microbiota. Importantly, CCzymes also increased the levels of bile acids and indole derivatives, thereby contributing to the restoration of intestinal barrier integrity.

The review begins by elucidating the mechanisms through which NMs modulate innate and adaptive immune responses in the context of NDs. These mechanisms encompass the dampening of innate immune cell activation, particularly microglia and astrocytes, and the restriction of peripheral adaptive immune cell infiltration into the central nervous system (CNS). By doing so, NMs can alleviate neuroinflammation and promote the repair of damage induced by NDs. The review emphasizes the application of stimulus-responsive NMs for targeted immunomodulation within the CNS. Moreover, it discusses strategies to enhance NM targeting and develop of NM-based active immunotherapies as prospective therapeutic approaches for clinical application. Understanding the mechanisms and applications of NMs is pivotal for unlocking their full potential in immunomodulatory strategies.

Regulating microglial activation to reshape the inflammatory microenvironments has increasingly become a promising therapeutic target for the treatment of neurological diseases. Retinoic acid, a natural small-molecule compound, holds potential neuroprotective and immunomodulatory properties. However, its poor water solubility poses a challenge to its bioavailability. In this study, calcium retinoate nanoparticles (Ca-RA NPs) were proposed and synthesized through a coordination reaction between retinoic acid molecules and calcium ions, which were proved to be easily endocytosed by microglia and rapidly decomposed into small molecule/ion storms in lysosomes. In vitro experimental results demonstrated that Ca-RA NPs can inhibit lipopolysaccharide (LPS)-induced M1 polarization of microglia while promoting their polarization toward the M2 phenotype. Furthermore, the mechanism underlying the anti-inflammatory effects of Ca-RA NPs on microglia is closely associated with the inhibition of mitogen-activated protein kinase and NF-κB signaling pathways. Notably, cell co-culture experiments revealed that Ca-RA NPs mediated immune microenvironment can indirectly promote neuronal differentiation of neural stem cells (NSCs) by selectively modulating microglial M1/M2 polarization. In vivo experimental results further demonstrated that Ca-RA NPs can not only alleviate the local inflammatory microenvironment but also promote the neuronal differentiation of endogenous NSCs to repair damaged neurons, thereby improving the behavioral functions of LPS-induced neuroinflammatory mice.
