Poison ivy

If you’ve ever had a brush with leaves of the poison ivy or similar plants, you know just how painful the resulting itchy rash can be. American scientists have recently discovered that an immune molecule called CD1a causes this skin irritation after contact with urushiol, the 'active ingredient' found in such plants. Let’s hope that their finding brings us a little bit closer to formulating effective medications able to counter these inflammations. It may eventually even shed some light on psoriasis and other serious skin conditions.
