We established some new protein adductions of proteins by lipid-derived electrophilic aldehydes. To verify the presence of the protein-bound ligands in vivo, we raised a monoclonal antibody against the ligands, characterized the epitopes, and immunohistochemically demonstrated the presence of the ligands in vivo. In addition, we developed high performance liquid chromatography with on-line electrospray ionization tandem mass spectrometry (LC/ESI/MS/MS)-based quantification methods and showed evidence that the ligands are indeed accumulated in vivo. We also established the danger signal function of these ligands. Furthermore, we characterized the multi-specificity mechanism of innate antibodies that recognize the modified proteins as antigenic ligands and established that they contribute to the removal of apoptotic cells and biological defense.
