" Scientists believe they may have discovered a new way to prevent donor corneas being rejected post-transplant. Using a mouse model, a team at the UT Southwestern Medical Center in the US found that when an immune system molecule called interferon-gamma (IFN-\u03B3) was blocked and the mice were already known to share the same major histocompatibility complex (MHC) genotype as the donor cornea, transplants were accepted 90 per cent of the time. However, the results were not as successful when either one of the techniques was applied separately. Writing in the American Journal of Transplantation, lead author Dr Jerry Niederkorn said: &amp;#039;When MHC matching is combined with anti-IFN-\u03B3 therapy, long-term corneal transplant survival is almost guaranteed.&amp;quot; He added that if the method can be found to work in humans, it is likely to be useful for individuals who have already rejected a cornea or are thought to be at risk of rejection, rather than everyone undergoing a transplant. According to NHS Blood and Transplant, 3,697 patients had their sight restored following a cornea transplant in 2012-13. Read the abstract "^^<http://www.w3.org/2001/XMLSchema#string>
