Drawing on the divergent pathologies of psoriasis and malignancies, we explored whether immunosuppressive mechanisms from the tumor microenvironment could be repurposed for psoriasis therapy. Utilizing B16-F10 melanoma cells as a model, we found that topical application of inactivated melanoma tissue homogenate alleviated psoriatic lesions in mice, primarily mediated by melanoma-derived exosomes. These exosomes exert therapeutic effects by modulating IL-17 signaling through miRNAs, effectively reducing T cell activation and proliferation. We discovered key miRNAs, mmu-miR-320-3p and mmu-miR-126-5p, that target IL-17a. Additionally, we demonstrated that these exosomes, enriched with RhoA protein, enhance transcytosis across epidermal barriers. Based on these insights, we developed ‘ExoLipo,’ a biomimetic exosomal formulation incorporating RhoA and loaded with mmu-miR-320-3p, inheriting the native exosomes' transdermal and immunomodulatory capacities. This formulation exhibited significant preventive and therapeutic effects on psoriasis mice models with an excellent safety profile.

A two-step <em>in vitro</em> dissolution method with implant formation in a biorelevant gel followed by incubation in release media showed a 30-day three-phase release profile with an initial burst release of 36.04 ± 4.23 %, a plateau, and a controlled release up to 93.75 ± 4.68 % at day 30, typical of PLGA-based implant formulations. Immediate and controlled-release formulations were tested in rat and rabbit animal models and confirmed that DKR-1677 is taken up by the retina after intravitreal administration.

However, the development of efficient nanocarriers that can overcome existing delivery challenges and ensure effective cellular uptake remains a critical hurdle. In this study, we aimed to address this issue by genetically modifying four lysine residues at the N-terminus of the FTH gene through gene recombinant technology, resulting in the creation of poly-lysine-H-apoferrin (4LF) vectors. These vectors were designed to efficiently deliver saRNA encoding the Sirtuin1 (Sirt1) protein to chondrocytes, thereby mitigating cartilage damage. The poly-lysine modification conferred the ability of 4LF@saRNA nanoparticles (NPs) to escape from lysosomes <em>via</em> proton sponge effects and to release saRNA into the cytoplasm through the pH-induced degradation of the 4LF vector, ultimately activating the target gene. To enhance the retention of NPs within the joint cavity and facilitate intra-articular delivery, we incorporated the 4LF@saRNA NPs into a thermosensitive self-healing hydrogel composed of chitosan, oxidized chondroitin sulfate (OCS), and sodium β-glycerophosphate (β-GP). Experimental results demonstrated that the chitosan/OCS/β-GP-4LF@saRNA (OCCG-4LF@saRNA) delivery system effectively delivered the 4LF@saRNA NPs to chondrocytes both <em>in vitro</em> and <em>in vivo</em>, resulting in a significant increase in Sirt1 protein expression. This upregulation led to a reduction in chondrocyte apoptosis, enhanced cell migration, and improved cartilage protection, effectively alleviating symptoms of osteoarthritis.
