IL-1 receptor/Toll-like receptor (IL-1R/TLR) supefamily represents a group of proteins that share highly conserved TIR domain in their cytoplasmic region. Signal transduction mediated by TIR-containing proteins involves the activation of NF-κB transcription factor and thus the members of this superfamily play a key role in many physiological responses related to innate immune defense and inflammation. SIGIRR (single immunoglobulin IL1R-related molecule) is a recently discovered member of the IL-1R family, however it differs from the other group members by its unique structural features. SIGIRRhas been so far considered to be an 'orphan' receptor as no SIGIRR ligand has been identified yet. Moreover, SIGIRR itself is not capable to induce the NF-κB activation. Instead, SIGIRR is supposed to act as a negative regulator for IL- 1Rs/TLRs mediated inflammation. Its inhibitory function has been implemented in several signalling pathways in various cell types and tissues including the kidney, the digestive tract and the lung. Recent reports also suggest that SIGIRR could play a role in early embryonic development. The main aim of this thesis is to characterize the mechanism how SIGIRR negative regulatory function in IL-1R/TLR signalling pathway is delivered. Here we describe the establishment of...
