Clear Skin: Injections counteract psoriasis in patients

Injections of an immune system protein can alleviate skin problems in people with psoriasis, a German-Dutch research team reports. The well-tolerated protein, called interleukin-4, works as well as a powerful standard therapy known to cause severe side effects. If the results are confirmed in larger studies, interleukin-4 could offer an alternative therapy for this difficult-to-treat disease.
