Description:	IIG Seminar Dr. Zuniga’s laboratory discovered that, in response to a viral infection, systemic type I interferons (IFN-I) are initially elevated but are subsequently and rapidly silenced despite continuous pathogen replication. They showed that there is an IFN-I refractory (or exhaustion) phase, during which the infected host fails to elevate IFN-I upon secondary unrelated infections, explaining delayed viral control and enhanced susceptibility to opportunistic infections. Dr. Zuniga will present their recent work on the mechanisms underlying the initial IFN-I elevation and its subsequent, rapid, suppression after viral infection.
