Proteins found on silicone breast implants
INNSBRUCK, Austria, Dec. 18 (UPI) -- Austrian researchers have reported they have detected proteins that accumulate on the surface of silicone breast implants after implants are in the body.
Georg Wick of the Medical University of Innsbruck and colleagues say that the proteins may be involved in causing immune reactions in patients from breast implants and other types of silicone implants.
The study involved 23 healthy women who had undergone breast augmentation for cosmetic reasons, including some who were removing or replacing implants due to complications.
The study, published in the Journal of Proteome Research, described how the scientists used a targeted proteomics approach to identify proteins adsorbed to the surface of silicone because those proteins have been identified as key components in local immune reactions to silicone.
"Thus far we have identified the 30 most abundant proteins deposited on the surface of silicone, the largest known inventory of such proteins so far," said Wick.
