Boosting a key protein in eye cells could help protect adults aged 50 and older against the biggest cause of sight loss, scientists have found. Age-related macular degeneration (AMD) – a common condition impacting the middle part of a person’s vision – affects around 700,000 people in the UK and currently has no effective treatments. A research team led by the University of Bristol discovered that increasing the levels of a protein called IRAK-M helped protect the retina – the thin layer of tissue at the back of the eye that is essential for maintaining vision.
The researchers said this breakthrough could potentially pave the way for gene therapies that could boost IRAK-M levels to protect against AMD . Andrew Dick, professor of ophthalmology from Bristol Medical School at the University of Bristol and director of the UCL Institute of Ophthalmology, said: “Our findings suggest that boosting a protein called IRAK-M could be a potential treatment strategy for AMD and could offer an exciting new therapeutic target for this common condition for which effective therapies remain elusive.” AMD mainly affects people over the age of 50.
It does not cause total blindness but can make everyday activities such as reading, driving and recognising faces difficult. The exact cause of AMD is unknown, but has been linked to smoking, high blood pressure, being overweight and having a family history of the disease. The IRAK-M protein is a key part of the immune system that helps pro.
