"WebImmunogenicity or immunoreactivity results from the biomaterial being detected by the body’s immune system as a foreign object. Immunoreactive biomaterials, especially wear particles, are detected by antigenic reactions on cells. A biochemical cascade then occurs, whereby T-helper cells migrate towards the biomaterial.
