The current study aimed to target the delivery of p-coumaric acid (CA), a dietary polyphenol to the synovial macrophages of AIA rats via mannose incorporated liposomal delivery system (ML) with reference to osteoclastogenesis and bone resorption. In vivo imaging and in vitro drug release study indicated the efficiency of mannosylated liposomes to localize at the site of inflammation and increased sustain drug release respectively. Morphological assessment of isolated synovial macrophages with respect to CD86 (synovial macrophages) and CD51 (pre-/osteoclast) indicated that p-coumaric acid encapsulated mannosylated liposomes (ML-CA) inhibited the osteoclasts differentiation. ML-CA treatment inhibited the TRAP staining, downregulated the expression of MMP-9 and NFATc1 and inflammatory cytokines. The ex-vivo study specified the ability of CA to induce the OPG production in bone marrow stromal cell triggered macrophage-osteoclasts differentiation and to preserve the calcium content. Taken together, our results demonstrated that ML-CA could intervene in the osteoclast formation. © 2018 Elsevier B.V.
