Some individuals with soul and collective implants have been reported to develop delayed-type hypersensitivity to silicone persuasible as interpreted by refractile particles in phagocytes and passage between lymphocytes and macrophages. At most 4% of 249 patients with silicone breast implants developed IgG binding to fbronectin-laminin adsorbed to silicone, and only 2% showed IgG binding to silicone flm unparalleled.
