IFNA5 / IFNaG蛋白背景綜述

Interferons (IFNs) are natural glycoproteins belonging to the cytokine superfamily, and are produced by a wide variety of cells types in response to challenges by foreign agents such as viruses, parasites and tumor cells. There are three major classes of IFNs according to the receptor type through which they signal, and the type I IFNs bind to a specific receptor complex known as the IFN-α receptor (IFNAR) consisting of IFNAR1 and IFNAR2 chains. The type I IFNs present in humans are IFN-α, IFN-β and IFN-ω, and the IFN-α come in 13 subtypes whose encoding genes locate in a cluster on chromosome 9. IFN-α is produced by leukocytes and mainly involved in innate immune response against viral infection together with other IFNs. IFN-α is produced in response to the presence of dsRNA, a key indicator of viral infection via Toll Like Receptors, and assists the immune response by inhibiting viral replication within host cells, activating natural killer cells and macrophages, increasing antigen presentation to lymphocytes, and inducing the resistance of host cells to viral infection. IFN-α also acts as a pyrogenic factor and thus causes fever by binding to opioid receptors and eliciting the release of prostaglandin-E2, and serves as an analgesic by employing the similar mechanism. Furthermore, IFN-α is suggested to promote apoptosis and accordingly has therapeutic effect against certain cancers by inducing increased production of the p53 gene product. Here, the IFN-α G referrs to the human IFNA5 subtype.
