Abstract:
Studies in Chronic Granulomatous Disease showed two breakthroughs during this past decade. First, the discovery of 7 Nox/Duox family proteins, Noxo1 and Noxa1 (homologues of gp91(phox), p47(phox) and p67(phox)) may clarify novel physiological mechanisms for superoxide regulation in various organs, such as the regulation of blood pressure, mucosal defense system in respiratory/digestive tract and nephron. Secondly, the success in bone marrow transplantation and gene therapy for CGD should facilitate treatment for other genetic diseases as well.
