Antiviral response to infectious pathogenes; toll-like receptors; role of the family of IRF-factors; HIV-1 , IRF and IFN receptor null mice-response to viral infection; oncogenesis.
I have been working in the field of the innate immune response for most of my life, with recent focus on the transcription factors of IRF family. We were the first to identify and clone IRF-3 and have shown the role of IRF-3 and IRF-7 in the interferon induction. We were also the first laboratory which cloned and fuctionally characterized IRF-5 both in vitro and in vivo and have shown its role in the induction of inflammatory and antiviral cytokines as well as in apoptosis. Recently we have generated IRF-5 null mice and have shown that these mice cannot generate effective antiviral and anti-inflammatory response to viral infection, as well as demonstrated that IRF-5 plays a critical role in the TH-1 mediated response to Leishmania infection. We have also demonstrated that IRF-5 plays a critical role in B cells differentiation and in the response to T cells dependent and T cells independed immunie response, with the major effect in IgG2a response. These data indicate that IRF-5 may be one of the mediators of a cross talk between innate and adaptive immune responses. Most importantly, the data on the analysis of IRF-5 function are of clinical importance, since distinct genetic variations in IRF-5 gene were shown to be associated with many autoimmune diseases including lupus.
