Most nucleated cells produce one or more Type I IFNs in response to viral infection. Secreted Type I IFN then induces viral protective responses in neighboring non-infected cells. Type I IFNs also enhance virus-induced apoptosis. Other IFN-α1 activities include enhancement of dendritic cell maturation and cytotoxic T cell activity. IFN-α1 binds to the IFN-αR1 and IFN-αR2 heterodimer.Intracellular signaling through the Jak\/Stat pathway is best characterized. However, the PI3K, ERK, and p38 kinase pathways are also involved. Type I IFNs also appear to have an integral role in several autoimmune diseases.\u003c\/p\u003e\u003ch2\u003eBiological significance and function\u003c\/h2\u003e\u003cp\u003eFunctionally, \u003cstrong\u003eIFN-α1a\u003c\/strong\u003e mediates intercellular communication in immune and stress-response settings through receptor engagement and downstream transcriptional programs.
