To the Editor:

Your article on asthma [Mapping the Landscape of Asthma, Winter 1999] explained very nicely the ever-increasing problem this disease represents in the United States and worldwide, as well as the efforts at Yale to address this pressing problem. I wish, however, to point out that the inducible transgenic mouse that was described, in which genes can be turned on and off at will, was not prepared solely in my laboratory. It was a collaborative effort of a number of laboratories including that of Prabir Ray, Ph.D., associate professor of medicine in the Department of Internal Medicine.
