Interferons (IFNs) are cytokines produced and secreted by virtually all eukaryotic cells in response to stimulation by certain viruses, bacteria, antigens, and mitogens. They mediate their biological activity by binding to specific receptors on the cell surface. These proteins were named IFNs because they interfere with the viruses’ replication ... 2, record 1, English, - interferon

Interferons are a family of naturally occurring small proteins that are produced and secreted by cells in response to viral infection. Alpha and beta interferons are classified type 1 interferons and include more than 25 different molecules. Consensus interferon(CIFN) is a novel, recombinant type 1 interferon containing 166 amino acids. CIFN was derived by scanning the sequences of natural alpha interferons and assigning the most frequently observed amino acid in each corresponding position. CIFN, when compared on an equal mass basis with interferon(IFN) alfa-2 and alpha-2b in in vitro assays, typically displays 5-10 tiems higher biological activity. 1, record 8, English, - Consensus%20Interferon

On attribue à chaque tronçon, ou sous-bassin, un indice X-Y-Z correspondant à un débit donné. On propose "débit d'entrée", parce que le "in-flow" correspond à un débit affluent (ou débit d'entrée), par opposition à un "outflow" (débit défluent).
