    Impairment of mycobacterial immunity in human interleukin-12 receptor deficiency (1998)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1998-06-20
    Description: In humans, interferon gamma (IFN-gamma) receptor deficiency leads to a predisposition to mycobacterial infections and impairs the formation of mature granulomas. Interleukin-12 (IL-12) receptor deficiency was found in otherwise healthy individuals with mycobacterial infections. Mature granulomas were seen, surrounded by T cells and centered with epithelioid and multinucleated giant cells, yet reduced IFN-gamma concentrations were found to be secreted by activated natural killer and T cells. Thus, IL-12-dependent IFN-gamma secretion in humans seems essential in the control of mycobacterial infections, despite the formation of mature granulomas due to IL-12-independent IFN-gamma secretion.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Altare, F -- Durandy, A -- Lammas, D -- Emile, J F -- Lamhamedi, S -- Le Deist, F -- Drysdale, P -- Jouanguy, E -- Doffinger, R -- Bernaudin, F -- Jeppsson, O -- Gollob, J A -- Meinl, E -- Segal, A W -- Fischer, A -- Kumararatne, D -- Casanova, J L -- New York, N.Y. -- Science. 1998 May 29;280(5368):1432-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉INSERM U429, Hopital Necker-Enfants Malades, Paris 75015, France.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/9603732" target="_blank"〉PubMed〈/a〉

    Pyogenic bacterial infections in humans with IRAK-4 deficiency (2003)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2003-03-15
    Description: Members of the Toll-like receptor (TLR) and interleukin-1 receptor (IL-1R) superfamily share an intracytoplasmic Toll-IL-1 receptor (TIR) domain, which mediates recruitment of the interleukin-1 receptor-associated kinase (IRAK) complex via TIR-containing adapter molecules. We describe three unrelated children with inherited IRAK-4 deficiency. Their blood and fibroblast cells did not activate nuclear factor kappaB and mitogen-activated protein kinase (MAPK) and failed to induce downstream cytokines in response to any of the known ligands of TIR-bearing receptors. The otherwise healthy children developed infections caused by pyogenic bacteria. These findings suggest that, in humans, the TIR-IRAK signaling pathway is crucial for protective immunity against specific bacteria but is redundant against most other microorganisms.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Picard, Capucine -- Puel, Anne -- Bonnet, Marion -- Ku, Cheng-Lung -- Bustamante, Jacinta -- Yang, Kun -- Soudais, Claire -- Dupuis, Stephanie -- Feinberg, Jacqueline -- Fieschi, Claire -- Elbim, Carole -- Hitchcock, Remi -- Lammas, David -- Davies, Graham -- Al-Ghonaium, Abdulaziz -- Al-Rayes, Hassan -- Al-Jumaah, Sulaiman -- Al-Hajjar, Sami -- Al-Mohsen, Ibrahim Zaid -- Frayha, Husn H -- Rucker, Rajivi -- Hawn, Thomas R -- Aderem, Alan -- Tufenkeji, Haysam -- Haraguchi, Soichi -- Day, Noorbibi K -- Good, Robert A -- Gougerot-Pocidalo, Marie-Anne -- Ozinsky, Adrian -- Casanova, Jean-Laurent -- New York, N.Y. -- Science. 2003 Mar 28;299(5615):2076-9.
