Transcutaneous delivery of mung bean-derived nanoparticles for amelioration of psoriasis-like skin inflammation

Psoriasis is a complex autoimmune disease that is closely associated with the disorganized pro-inflammatory polarization of macrophages and the activation of inflammatory signalling pathways. Nanoparticles (NPs) have shown their potential in immune response regulation and the related treatment of inflammatory diseases. Herein, we report the modulation of the skin immune system for amelioration of psoriasis-like skin inflammation using mung bean-derived NPs (MBNs), which exhibit high antioxidant activity to reduce reactive oxygen species (ROS) and modulate the immune microenvironment. For imiquimod (IMQ)-stimulated psoriasis-like skin, topical administration of MBNs can achieve the homeostasis of polarized macrophages and antagonize the activation of the nuclear factor kappa B (NF-kappa B) signalling pathway, which result in the alleviation of skin inflammation. The transcutaneous delivery of MBNs provides a promising approach for the treatment of psoriasis and other inflammatory skin diseases.

Automated summary

This study reports the modulation of the skin immune system using mung bean-derived nanoparticles for the amelioration of psoriasis-like skin inflammation. These nanoparticles exhibit high antioxidant activity and can reduce reactive oxygen species and modulate the immune microenvironment. Topical administration of these nanoparticles can achieve the homeostasis of polarized macrophages and antagonize the activation of inflammatory signaling pathways, resulting in the alleviation of skin inflammation.
