Abstract

Humans as models of human disease Mice are a convenient model for exploring the functions of cellular signaling pathways. Occasionally, however, an “experiment of nature” highlights the perils of overreliance on mice. RIPK1 is a well studied protein kinase that regulates cell death. Mice deficient in RIPK1 die soon after birth because of the protein's widespread role in multiple tissues and organs. Cuchet-Lourenço et al. studied patients with inherited immunodeficiency of unknown cause (see the Perspective by Pasparakis and Kelliher). They identified inactivating mutations in the RIPK1 gene in four individuals. Unlike what has been seen in mice, the deleterious effects of RIPK1 loss in humans were confined to the immune system, a finding with potential therapeutic implications.
