摘要

The present invention relates to a novel antagonist of the Toll-like receptor 4 (TLR-4). More specifically, the present invention relates to a lipopolysaccharide (LPS) isolated from the bacterium Bartonella quintana as a novel antagonist of the Toll-like receptor 4 (TLR-4). Further, the present invention relates to the use of said natural antagonist for the treatment of an autoimmune or inflammatory disease in a mammal and specifically for the treatment of rheumatoid arthritis (RA). Furthermore, the present invention relates to pharmaceutical compositions comprising a lipopolysaccharide (LPS) isolated from the bacterium Bartonella quintana.
