ISRE

ISRE stands for Interferon-Stimulated Response Elements, which are specific DNA sequences found in the promoters of certain genes. When the body detects a viral infection, it produces interferons—proteins that alert cells to defend against the virus. These interferons activate proteins that bind to ISREs, turning on genes involved in immune defense, antiviral activity, and cell regulation. Essentially, ISREs act as switches that help turn on genes necessary for the immune system to respond effectively to infections. They are key to coordinating the body's antiviral response at the genetic level.
