Abstract

Liver fibrosis is a global life-threatening disorder with no approved treatment. It leads to serious hepatic complications when progressive, such as cirrhosis and carcinoma. Luteolin (LUT) is a plant flavonoid possessing a promising therapeutic potential in various liver diseases particularly, liver fibrosis. It was reported to have potent anti-inflammatory and antioxidant properties. It also suppresses the proliferation of activated hepatic stellate cells (HSC) and induces their apoptosis. However, its poor aqueous solubility and exposure to metabolism hinder its clinical use. Mesenchymal stem cells (MSCs)-derived exosomes, nano-sized extracellular vesicles, have recently emerged as natural biocompatible drug delivery vehicles permitting efficient drug delivery. Accordingly, the present study aimed for the first time to investigate the potential of bone marrow MSCs-derived exosomes to improve LUTs antifibrotic effectiveness. LUT-loaded exosomes (LUT-Ex) were successfully developed, optimized and subjected to both in vitro and in vivo characterization. The elaborated LUT-Ex presented good colloidal properties (size; 150 nm, PDI; 0.3 and ζ-potential; −28 mV), typical vesicular shape, reasonable drug entrapment efficiency (40%) with sustained drug release over 72 h. Additionally, the cellular uptake study of coumarin-6-loaded exosomes in HEP-G2 revealed a significant enhancement in their uptake by 78.4% versus free coumarin-6 solution (p ≤ 0.001). Following a single intraperitoneal injection, LUT-Ex revealed a superior antifibrotic activity compared with either LUT-suspension or blank exosomes as evidenced by the results of biochemical and histopathological evaluation. In conclusion, the elaborated LUT-Ex could be addressed as a promising nanocarrier for effective treatment of liver fibrosis.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
