The expression of cytokines and β -defensin 2, - 3, -4 in rabbit bone tissue after hydroxyapatite (HAp), α- Tricalcium phosphate (α-TCP) and polymethylmethacrylate (PMMA) implantation

Jolanta Vamze、Māra Pilmane、Andrejs Skaģers2012-08-20IOP Conference Series Materials Science and Engineering

Bone loss induced by inflammation is one of the complications after biomaterial implantation. There is no much data on expression of cytokines and defensins into the bone tissue around the implants in literature. The aim of this work was to investigate the distribution and appearance of interleukin (IL)-1, IL-6, IL-8,…
