Scientific summary

The innate immune system provides the first barrier against pathogens. At the steady state, intracellular TLRs (TLR3, 7, 8 and 9) are retained in the endoplasmic reticulum together with a chaperone molecule, UNC93B1. Upon stimulation, they relocate to the endo/lysosomal compartment, thus allowing binding to their ligands and the recruitment of their adaptor molecules, MyD88 or TRIF. It has been shown that mouse TLR9 requires proteolytic cleavage in the endosomes to be functional. We are investigating which proteases regulate endosomal TLRs signaling and the role of these TLRs and chaperone molecules in the MHC class I antigen cross presentation pathway in dendritic cells. Our results indicate that AEP is a unique protease processing TLR7 and TLR9 in dendritic cells opening new therapeutical possibilities for the treatment of inflammatory and cancer diseases where TLR7 and 9 pathways are dysregulated.
