Research Abstract

We detected a bronchoconstrictive activity produced by T cells in non-atopic asthmatics. The gels embedded normal human bronchial smooth muscle cells contracted gradually and continuously by the culture supernatant of T cells, like the contraction induced by leukotrienes which play critical role in the late asthmatic reaction. It was suggested that this bronchoconstrictive activity is novel one, because the molecular weight and the response of antagonist/immunosuppressant were different from well-known bronchoconstrictors.
