Research interests

    During the Ph.D., Ivan Zanoni (IZ) focus was to investigate the fate of auto-reactive T cells in the periphery and its consequences for autoimmune diseases. This problem was further investigated using transgenic mouse models in which antigen expression was limited to different types of antigen presenting cells. IZ also pioneered several studies on the interaction between Dendritic Cells (DCs) and Natural Killer (NK) cells during bacterial infections. DCs are sentinels of the immune system that link the innate and adaptive immune responses. During the initial phases of their activation DCs interact with NK cells and activate their anti-bacterial functions. In this context, several molecular mechanisms used by DCs have been described.
    IZ has been also studying Pattern Recognition Receptor (PRRs) signaling pathways. PRRs are the receptors that initiate immunity to infection. In particular, IZ started to work on the interaction between lipopolysaccharide (LPS) and its multi-receptor complex (TLR4-MD2-CD14), identifying new signal transduction pathways specific for different cell types of the innate immune system. We have demonstrated that, in response to LPS, CD14 regulates a TLR4 independent signal transduction pathway in DCs that induces NFAT activation and that control DC’s life cycle.
    Recently, we extended also to other cell types the knowledge that CD14 is able to act independently of TLR4 and that CD14 is required for the microbe-induced endocytosis of TLR4 that leads to type I interferons production, potent antibacterial and anti-tumoral mediators.
