Structural engineerStructural engineers analyze, design, plan, and research structural components and structural systems to achieve design goals and ensure the safety and comfort of users or occupants. Their work takes account mainly of safety, technical, economic, and environmental concerns, but they may also consider aesthetic and social factors. Structural engineering is usually considered a specialty discipline within civil engineering, but it can also be studied in its own right.
Binding siteIn biochemistry and molecular biology, a binding site is a region on a macromolecule such as a protein that binds to another molecule with specificity. The binding partner of the macromolecule is often referred to as a ligand. Ligands may include other proteins (resulting in a protein-protein interaction), enzyme substrates, second messengers, hormones, or allosteric modulators. The binding event is often, but not always, accompanied by a conformational change that alters the protein's function.
Virus d'Epstein-BarrLe virus d'Epstein-Barr (aussi appelé EBV) ou virus de l’herpès 4 (HHV-4) est un virus de la famille des Herpesviridae. Il fait partie de la sous-famille des . Le virus d'Epstein-Barr cause plusieurs maladies dont la mononucléose infectieuse et le lymphome de Burkitt. Le virus cible les lymphocytes B humains via leur récepteur CD21. La protéine qu'il produit lors de l'infection de ces cellules, peut recruter des facteurs de transcription (FT) humains et ainsi causer des maladies auto-immunes comme le lupus ou le diabète de type 1 mais aussi la sclérose en plaques.
