We have relocated in February 2017 to the NIH. By now, the laboratory is up and running and we have made substantial progress in the aims set for this year: A. Regulation of C3 and C5 gene expression: The controlled regulation of C3 and/or C5 gene expression ideally from the cell surface - would be an additional means to manipulate Th1 responses at will. In collaboration with Steve Holland (NIAID, NIH) and Adrian Hayday (KCL), we have identified the integrin LFA-1 as a master regulator of C3 gene expression in a range of immune cells and are currently assessing the in vivo significance and druggability of this novel integrin/complement crosstalk. B. Direct regulation of IL-10 production: We have identified a receptor that, when activated, completely abrogates IL-10 switching in Th1 cells.We are currently assessing the signaling pathway driven by this receptor that leads to the loss of IL-10 production in CD4+ T cells.
