Exosomal Curcumin: Its Bioavailability And Potential Anti-Inflammation Activity, Dongmei Sun Jan 2010

Exosomal Curcumin: Its Bioavailability And Potential Anti-Inflammation Activity, Dongmei Sun

Curcumin, a pleiotropic polyphenol derived from turmeric plants Curcuma Longa with rhizome, exhibits strong evidence as an anti-inflammation, anti-oxidant and anti-cancer reagent both in vitro and in vivo. Due to its low stability and systemic bioavailability, a large amount of curcumin has to be administrated to achieve therapeutic effects both in animal and in human. The major effort to overcome this barrier is making by encapsulation of curcumin into nanoparticles such as polymers and liposomes; some promising data have demonstrated the effectiveness of such method. Exosomes are vesicle-like nanoparticles secreted by living cells. Exosomes contain both cell surface molecules and …

The receptor activator of NF-қB (RANK) ligand (RANKL) and its receptor RANK play a critical role in osteoclast biology. RANK has three tumor necrosis factor receptor associated factor (TRAF)-binding motifs [PFQEP369-373 (Motif 1), PVQEET559-564 (Motif 2), and PVQEQG604-609 (Motif 3)] that regulate osteoclast formation and function. RANK also contains a TRAF-independent motif (IVVY535-538) that commits bone marrow macrophages (BMMs), which are osteoclast precursors, to the osteoclast lineage for osteoclastogenesis. Notably, tumor necrosis factor-α (TNF) and interlukin-1 (IL-1) utilize TRAFs to initiate most of the signaling pathways known to be activated by RANKL but fail to form osteoclasts unless attended by …
