An enhanced RRM2 siRNA delivery to rheumatoid arthritis fibroblast-like synoviocytes through a liposome ‑protamine-DNA-siRNA complex with cell permeable peptides.
An enhanced RRM2 siRNA delivery to rheumatoid arthritis fibroblast-like synoviocytes through a liposome‑protamine-DNA-siRNA complex with cell permeable peptides. Int J Mol Med. 2018 Aug 08;: Authors: Wang X, Wang X, Sun J, Fu S Abstract Rheumatoid arthritis (RA) is considered to be a systemic autoimmune disease that induces systemic complications and progressive disability. It affects a large number of people. RA fibroblast‑like synoviocytes (RA‑FLS) promote the progression of RA through the secretion of proinflammatory cytokines and increasing invasiveness into the extracellular matrix. Therefo...

Radicals Scavenging MOFs Enabling Targeting Delivery of siRNA for Rheumatoid Arthritis Therapy
An active targeting nanomedicine based on metal-organic frameworks is synthesized through coordination between tannic acid and Fe3+, loaded with anti-TNF- α siRNA and then modified with bovine serum albumin. The nanosystem can selectively accumulate in inflamed joints, be selectively delivered into M1 macrophages, and exert anti-RA efficacy through the synergistic effects between MOF vector and anti-TNF-α siRNA. AbstractMacrophages play essential roles in the progression of rheumatoid arthritis (RA), which are polarized into the pro-inflammatory M1 phenotype with significant oxidative stress and cytokines excretion. Here...

Peptide-siRNA nanocomplexes targeting NF-κB subunit p65 suppress nascent experimental arthritis
The NF-κB signaling pathway is implicated in various inflammatory diseases, including rheumatoid arthritis (RA); therefore, inhibition of this pathway has the potential to ameliorate an array of inflammatory diseases. Given that NF-κB signaling is critical for many immune cell functions, systemic blockade of this pathway may lead to detrimental side effects. siRNAs coupled with a safe and effective delivery nanoplatform may afford the specificity lacking in systemic administration of small-molecule inhibitors. Here we demonstrated that a melittin-derived cationic amphipathic peptide combined with siRNA targeting the p65 ...

siRNA Delivery Impedes the Temporal Expression of Cytokine-Activated VCAM1 on Endothelial Cells.
Abstract Leukocyte recruitment plays a key role in chronic inflammatory diseases such as cardiovascular disease, rheumatoid arthritis, and cancer. Leukocyte rolling and arrest are mediated in part by the temporally-regulated surface expression of vascular cell adhesion molecule-1 (VCAM1) on endothelial cells (ECs). In this paper, we engineered a pH-responsive vehicle comprised of 30 mol% dimethylaminoethyl methacrylate (30D) and 70 mol% hydroxyethyl methacrylate (70H) to encapsulate, protect, and deliver VCAM1 small interfering RNA (siRNA). The ability of siRNA to reduce VCAM1 gene expression is in direct opposi...

Targeted knockout of TNF‑α by injection of lentivirus‑mediated siRNA into the subacromial bursa for the treatment of subacromial bursitis in rats.
Authors: Wang Y, Li Q, Wei X, Xu J, Chen Q, Song S, Lu Z, Wang Z Abstract Subacromial bursitis (SAB) is the major source of pain in rotator cuff disease. Although multiple investigations have provided support for the role of inflammatory cytokines in SAB, few have focussed on the use these cytokines in the treatment of SAB. The aim of the present study was to observe the therapeutic efficacy of lentivirus‑mediated RNA interference (RNAi) on carrageenan‑induced SAB by injecting lentivirus‑tumor necrosis factor (TNF)‑α‑RNAi expressing TNF‑α small interfering (si)RNA. Using screened siRNA segments, an si...

Targeting NF-kB signaling with polymeric hybrid micelles that co-deliver siRNA and dexamethasone for arthritis therapy.
Abstract The transcription factor NF-kB plays a pivotal role in the pathogenesis of rheumatoid arthritis. Here we attempt to slow arthritis progression by co-delivering the glucocorticoid dexamethasone (Dex) and small-interfering RNA targeting NF-kB p65 using our previously developed polymeric hybrid micelle system. These micelles contain two similar amphiphilic copolymers: polycaprolactone-polyethylenimine (PCL-PEI) and polycaprolactone-polyethyleneglycol (PCL-PEG). The hybrid micelles loaded with Dex and siRNA effectively inhibited NF-kB signaling in murine macrophages more efficiently than micelles containing e...

Nanoparticle-facilitated delivery of BAFF-R siRNA for B cell intervention and rheumatoid arthritis therapy.
Abstract The present study was designed to explore the effects of B-cell activating factor receptor (BAFF-R) siRNA encapsulated nanoparticles on collagen-induced arthritis (CIA). BAFF-R siRNA encapsulated nanoparticles (NP-siBAFF-R) were constructed using a double emulsion method and was characterized by dynamic light scattering and transmission electron microscopy. Cellular uptake of nanoparticles was determined using flow cytometry. The CIA mouse model was established and the mice were intravenously injected with nanoparticles. NP-siBAFF-R effectively decreased the expression of BAFF-R in B cells and facilitated...

siRNA-mediated c-Rel knockdown ameliorates collagen-induced arthritis in mice.
Abstract Previous studies have shown that inflammatory mediators involved in the development of rheumatoid arthritis (RA) are regulated by the Rel/nuclear factor-κB (Rel/NF-κB) transcription factor family. c-Rel, a member of the Rel/NF-κB family that is preferentially expressed by immune cells, is a risk factor for several inflammatory diseases including RA. In the current study, we investigated whether targeting c-Rel can be used to treat collagen-induced arthritis, an animal model for RA. c-Rel specific siRNA (siRel) delivered by nanoparticles was used to knockdown the expression of c-Rel. Our results showed ...

Study of Double-Targeting Nanoparticles Loaded With MCL-1 siRNA and Dexamethasone for Adjuvant-induced Arthritis Therapy.
In this study, HA-coated pH-responsive nanoparticles loaded with MCL-1 small interfering RNA (siRNA) and dexamethasone (HNPs/MD) were developed for RA treatment. The HNPs/MD had a mean particle size of 117.07 ± 2.21 nm and zeta potential of 15.53 ± 1.06 mV. The release rates of both MCL-1 siRNA and dexamethasone from the HNPs/MD at pH 4.5 and 6.0 were higher than those at pH 7.4, indicating that the nanoparticles were acid-sensitive. Cytotoxicity assays showed that compared with single drug loaded nanoparticles, the HNPs/MD showed higher cytotoxicity to activated macrophages. The superior therapeutic effect of HNPs/MD wa...
