Frog's immune system is key in fight against killer virus
Date:2/27/2009

Scientists from Queen Mary, University of London have discovered how changes to a frog's immune system may be the key to beating a viral infection which is devastating frog populations across the UK.

Communities of common frogs (Rana temporaria) are being struck down by a foreign virus which is estimated to be killing tens of thousands of frogs in the UK each year. When it strikes garden ponds, the surrounding lawn becomes strewn with dead frogs, some with skin ulcers so severe they reduce limbs to stumps, others with internal bleeding. The virus, called Ranavirus, has invaded the home counties around London, and is now spreading north and west.

Writing in the journal PLoS One, Dr Amber Teacher describes how the frogs' immune system has responded to the virus. Working with her fellow scientists at Queen Mary, University of London and experts at the Institute of Zoology, she studied ponds where Ranavirus deaths are occurring year after year, and consistently found changes to a gene called the MHC, which codes for a major part of the frog's immune system.

Dr Teacher explains: "It seems, as Darwin would have predicted, that the plucky surviving frogs have passed on to their descendants an immune system which is better tuned to the new threat."

Teacher also found that the frogs' immune systems are simpler than many other animals, including humans, who have several MHC genes doing a similar job. She adds: "This discovery has helped identify the point in our evolutionary history when this multiplication of genes occurred. With luck, even the frog's simpler system will be sufficient to win their battle".

It is too early to determine if the adaptation in the frogs' immune response will be enough to save them from the virus. Her colleague Professor Richard Nichols, from Queen Mary's School of Biological and Chemical Sciences added: "From a scientific point of view we could learn as much about the fight against vi
