'3-D' test could reduce reliance on animals for testing asthma and allergy medications

To determine whether new medicines are safe and effective for humans, researchers must first test them in animals, which is costly and time-consuming, as well as ethically challenging. Scientists now report that they've developed a simple, '3-D' laboratory method to test asthma and allergy medications that mimics what happens in the body, which could help reduce the need for animal testing.
