Lyme Stimulates More Inflammation

The agent of Lyme disease, Borrelia burgdorferi, produces membrane lipoproteins possessing potent inflammatory properties linked to disease pathology. A recent study served to prove the hyper-inflammatory response that Lyme patients often experience. The recent association of toll-like receptors (TLR) 2 and 4 with Lipopolysaccaride (LPS) responses prompted the examination of TLR involvement in lipoprotein signaling.

Futhermore, TLR2-dependent signaling by lipoproteins was facilitated by CD14. These data indicate that TLR2 facilitates the inflammatory events associated with Lyme arthritis. In addition, the widespread expression of lipoproteins by other bacterial species suggests that this interaction may have broad implications in microbial inflammation and pathogenesis.
