Metal orthopedic implant debris-induced osteolysis of hip bone is a major problem in patients with prosthetic-hips. Although macrophages are the principal targets for implant-wear debris, the receptor(s) and mechanisms underlying these responses are not fully elucidated. We examined whether the TLR4 pathway mediates immune response to metal-on-metal (MoM)(More)
The drug-eluting stent platform has a limited surface area, and a polymer carrier matrix is coated to enable sufficient loading of drugs. The development of a suitable polymer has been challenging because it must exhibit biocompatibility with the intravascular milieu. The use of biodegradable polymers seems to be attractive because it enables drug release(More)
Multinucleate giant cells (MGCs) are formed by the fusion of 5 to 15 monocytes or macrophages. MGCs can be generated by hip implants at the site where the metal surface of the device is in close contact with tissue. MGCs play a critical role in the inflammatory processes associated with adverse events such as aseptic loosening of the prosthetic joints and(More)
