Description: Severe influenza disease strikes otherwise healthy children and remains unexplained. We report compound heterozygous null mutations in IRF7, which encodes the transcription factor interferon regulatory factor 7, in an otherwise healthy child who suffered life-threatening influenza during primary infection. In response to influenza virus, the patient's leukocytes and plasmacytoid dendritic cells produced very little type I and III interferons (IFNs). Moreover, the patient's dermal fibroblasts and induced pluripotent stem cell (iPSC)-derived pulmonary epithelial cells produced reduced amounts of type I IFN and displayed increased influenza virus replication. These findings suggest that IRF7-dependent amplification of type I and III IFNs is required for protection against primary infection by influenza virus in humans. They also show that severe influenza may result from single-gene inborn errors of immunity.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4431581/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4431581/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Ciancanelli, Michael J -- Huang, Sarah X L -- Luthra, Priya -- Garner, Hannah -- Itan, Yuval -- Volpi, Stefano -- Lafaille, Fabien G -- Trouillet, Celine -- Schmolke, Mirco -- Albrecht, Randy A -- Israelsson, Elisabeth -- Lim, Hye Kyung -- Casadio, Melina -- Hermesh, Tamar -- Lorenzo, Lazaro -- Leung, Lawrence W -- Pedergnana, Vincent -- Boisson, Bertrand -- Okada, Satoshi -- Picard, Capucine -- Ringuier, Benedicte -- Troussier, Francoise -- Chaussabel, Damien -- Abel, Laurent -- Pellier, Isabelle -- Notarangelo, Luigi D -- Garcia-Sastre, Adolfo -- Basler, Christopher F -- Geissmann, Frederic -- Zhang, Shen-Ying -- Snoeck, Hans-Willem -- Casanova, Jean-Laurent -- 1U19AI109945/AI/NIAID NIH HHS/ -- 5R01AI100887/AI/NIAID NIH HHS/ -- 5R01NS072381/NS/NINDS NIH HHS/ -- 8UL1TR000043/TR/NCATS NIH HHS/ -- HHSN272201400008C/PHS HHS/ -- R01 AI100887/AI/NIAID NIH HHS/ -- R01 NS072381/NS/NINDS NIH HHS/ -- U19 AI109945/AI/NIAID NIH HHS/ -- Howard Hughes Medical Institute/ -- New York, N.Y. -- Science. 2015 Apr 24;348(6233):448-53. doi: 10.1126/science.aaa1578.
