Abstract
Sepsis, a life-threatening condition, often leads to multi-organ failure and has limited treatment options. We developed a novel dual-function nanoparticle, P2Ns-NAR(NAR), which utilizes naringenin (NAR) as both a targeting ligand for gut folate receptors and an encapsulated therapeutic agent to overcome its poor oral bioavailability. Here, we investigated the efficacy of this oral formulation in a mouse model of lipopolysaccharide-induced sepsis. We observed a significant reduction in the mRNA expression of pro-inflammatory (<i>Tlr4, NF-κB, and IL-18</i>), apoptotic (<i>p53</i>, and <i>Fas</i>), fibrosis (<i>TGFβ1</i> and <i>Smad3</i>) and inflammasome-related (<i>P2x7, gasdermin D, Nlrp3, Caspase 1, Nek7</i>) markers. Histological analyses showed a prevention of tissue injury in the lungs, liver, kidney, heart, brain, intestines, and spleen. Additionally, Masson's trichrome staining revealed a remarkable reduction in collagen deposition, a hallmark of fibrosis, across multiple organs such as the lungs, liver, kidney, and heart. Our findings establish this dual-function nanoparticle platform as a highly effective oral therapy to prevent multi-organ failure.
