Virginia Tech researcher discovers cellular contributor of Lyme arthritis that could open door to treatment | Virginia Tech Daily

Virginia Tech biochemist Brandon Jutras has found the cellular element that contributes to Lyme arthritis, a debilitating and intensely painful situation that is the most typical late stage symptom of Lyme illness.

Jutras discovered that because the Lyme-causing micro organism Borrelia burgdorferi multiplies, it sheds a cellular element referred to as peptidoglycan that elicits a singular inflammatory response within the physique.

“This discovery will help researchers improve diagnostic tests and may lead to new treatment options for patients suffering with Lyme arthritis,” mentioned Jutras, the lead creator on the examine. “This is an important finding, and we think that it has major implications for many manifestations of Lyme disease, not just Lyme arthritis.”

Reported incidences of Lyme illness, essentially the most reported vector-borne illness within the nation, have elevated by greater than 6,000 % prior to now 15 years within the state of Virginia. The Centers for Disease Control estimates that roughly 300,000 individuals are recognized with Lyme illness yearly within the United States. Scientists predict that the quantity of individuals who grow to be contaminated with Lyme will improve as our local weather continues to change. 

Jutras — an assistant professor of biochemistry within the College of Agriculture and Life Sciences and an affiliated college member of the Fralin Life Sciences Institute — and his collaborators not too long ago printed their findings within the Proceedings of the National Academy of Sciences.

The PNAS paper was 4 years within the making, and Jutras started this analysis throughout his post-doctoral fellowship within the lab of Christine Jacobs-Wagner, a Howard Hughes Medical Institute Investigator and professor at Yale University.

“Nowadays, nothing significant in science is accomplished without collaboration,” Jutras mentioned. Co-authors on this paper ranged from bench scientists to medical docs and practising physicians. Allen Steere, a Harvard physician who initially recognized Lyme illness within the 1970s, assisted Jutras along with his analysis and offered entry to affected person samples.

This analysis could present a brand new approach to diagnose Lyme illness and Lyme arthritis for sufferers with obscure signs based mostly on the presence of the cellular element referred to as peptidoglycan in synovial fluid.

The crew discovered peptidoglycan is a serious contributor to Lyme arthritis in late-stage Lyme illness sufferers. Peptidoglycan is a vital part of bacterial cell partitions. All micro organism have some type of peptidoglycan, however the type discovered within the micro organism that causes Lyme, Borrelia burgdorferi, has a singular chemical construction. When the micro organism multiply, they shed peptidoglycan into the extracellular setting, as a result of its genome doesn’t have the suitable proteins to recycle it again into the cell.
