A little guide for advanced search:

  • Tip 1. You can use quotes "" to search for an exact expression.
    Example: "cell division"
  • Tip 2. You can use + symbol to restrict results containing all words.
    Example: +cell +stem
  • Tip 3. You can use + and - symbols to force inclusion or exclusion of specific words.
    Example: +cell -stem
e.g. searching for members in projects tagged cancer

Les protéines IFITM (interferon-induced transmembrane proteins) font partie du système immunitaire inné et inhibent l’entrée de nombreux virus dans la cellule hôte. Elles agissent en modifiant les propriétés des membranes cellulaires, perturbant ainsi la fusion des virions. Dans le cas du VIH, elles exercent un effet antiviral supplémentaire dans la cellule infectée, en infiltrant les virions nouvellement produits et en diminuant leur potentiel infectieux. La structure, la localisation et les modifications post-traductionnelles régulant l’activité antivirale des protéines IFITM ont été récemment caractérisées. En plus des effets antiviraux, ces protéines possèdent d’autres activités au sein de la cellule. Dans cette revue, nous résumons les connaissances actuelles sur les différentes propriétés des protéines IFITM.
mots clés : VIH, fusion virale, interféron, IFITM
